The pith

Quantum many-body scars exhibit extensive ergotropy scaling in the PXP model.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper investigates the extractable energy, or ergotropy, stored in quantum many-body scars within the PXP model of Rydberg atoms. These scars evade thermalization and maintain low entanglement even at high energy density, unlike typical states that become passive with zero ergotropy in the large-system limit. By studying states that smoothly connect scars to thermal states, the work shows that ergotropy grows extensively with system size and correlates with entanglement in a way that extends prior free-fermion results to interacting systems. A simple dynamical protocol using a uniform coherent rotation is shown to recharge the system by injecting extractable energy, providing a concrete way to turn scarred states into a quantum battery.

Core claim

In the PXP model, families of states that interpolate between quantum many-body scars and thermal states display extensive ergotropy that scales linearly with system size. This occurs together with a phenomenological link between ergotropy and entanglement entropy that carries over from integrable free-fermion cases to this interacting model. A reset step consisting of a global uniform coherent rotation can inject extractable energy, demonstrating a workable protocol for charging a many-body quantum battery that is feasible on current Rydberg-atom arrays.

What carries the argument

Interpolating states between scars and thermal states in the PXP model, which carry the extensive ergotropy scaling and the ergotropy-entanglement relation.

If this is right

  • Scars can store extractable energy efficiently despite occupying only a small fraction of the Hilbert space.
  • Scarring offers a practical route to building quantum many-body batteries.
  • A uniform coherent rotation suffices to recharge the battery in a global reset step.
  • The ergotropy-entanglement relation provides a diagnostic that works for interacting as well as integrable systems.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • The same charging protocol may extend to other scarred Hamiltonians beyond the PXP model.
  • Entanglement could serve as a general proxy for estimating ergotropy in non-ergodic many-body states.
  • Engineering stronger scars or controlling their density might further improve battery performance.

Load-bearing premise

The phenomenological link between ergotropy and entanglement that holds for free fermions also holds for the interacting PXP model, and the interpolating states accurately reflect thermodynamic-limit behavior.

What would settle it

Numerical computation of ergotropy on larger PXP chains that shows sub-linear rather than linear growth with size, or direct measurement of vanishing ergotropy in the interpolating states at sizes where finite-size effects are expected to be small.

Quantum many-body scars break ergodicity and evade thermalization, resulting in sub-volume law entanglement entropy even with high energy density. While their quantum correlations and entanglement have been elaborated previously, their capacity in storing extractable energy, quantified by the notion ergotropy, remains an open question. Here we focus on the representative PXP model, and unveil the extensive ergotropy scaling of a family of states interpolating between quantum many-body scars and thermal states, the latter of which are known to be passive with vanishing ergotropy in the thermodynamic limit. A phenomenological relation between ergotropy and entanglement is uncovered, which generalizes the existing free fermion integrable results to an interacting scenario. The ergotropy in a dynamical protocol shows that a reset with a global uniform coherent rotation can inject extractable energy, as a proof of principle way to charge a quantum "battery". Our protocol is tailored for near term Rydberg neutral atoms array, while also being feasible for other quantum processors. Our results establish that quantum many-body scars, despite the tiny fraction of the Hilbert space they occupy, can be efficiently exploited for storing extractable energy, and "scarring" a many-body system as a promising route for engineering quantum many-body battery.

Referee Report

3 major / 2 minor

Summary. The paper investigates ergotropy in the PXP model, showing that a family of states interpolating between quantum many-body scars and thermal states exhibits extensive ergotropy scaling in the thermodynamic limit, in contrast to passive thermal states. It reports a phenomenological relation linking ergotropy to entanglement entropy that extends prior free-fermion results to interacting systems, and demonstrates a dynamical charging protocol via global coherent rotation, proposing scars as a route to quantum many-body batteries realizable in Rydberg arrays.

Significance. If the extensive ergotropy scaling and phenomenological relation hold without finite-size artifacts, the work would be significant for quantum thermodynamics and many-body physics, providing a concrete mechanism to exploit non-ergodic states for energy storage in near-term quantum hardware. The numerical evidence for scars enabling extractable work despite their small Hilbert-space fraction, combined with the proposed Rydberg protocol, strengthens the case for scarring as an engineering principle for quantum batteries.

major comments (3)
  1. [numerical results on ergotropy scaling] The central claim of extensive ergotropy scaling surviving L→∞ (abstract and numerical results section) rests on interpolating states whose behavior must be shown to be free of the known hybridization-induced weakening of PXP scars at larger sizes. The manuscript should include explicit finite-size scaling collapse or extrapolation plots for ergotropy density versus L, with data for at least L=20–30 if feasible, to rule out artifacts.
  2. [phenomenological relation and interpolating states] The phenomenological ergotropy-entanglement relation (reported in the results on interpolating states) is presented without details on the precise definition of the interpolating family, the range of system sizes, fitting procedure, or error bars. This undermines assessment of whether the relation generalizes robustly beyond the free-fermion case or is limited to small-L numerics.
  3. [dynamical protocol] The dynamical charging protocol (section on reset with global rotation) claims proof-of-principle for battery charging, but the analysis should quantify how the extractable work scales with system size and confirm that the post-rotation state remains in the scarred subspace without rapid leakage to thermal states.
minor comments (2)
  1. [methods] Clarify the exact construction of the interpolating states (e.g., linear combination parameters or variational ansatz) in the methods or appendix to allow reproducibility.
  2. [figures] Add a brief comparison table or plot contrasting ergotropy of scars, interpolating states, and thermal states across multiple L values for visual clarity.

  1. Referee: [numerical results on ergotropy scaling] The central claim of extensive ergotropy scaling surviving L→∞ (abstract and numerical results section) rests on interpolating states whose behavior must be shown to be free of the known hybridization-induced weakening of PXP scars at larger sizes. The manuscript should include explicit finite-size scaling collapse or extrapolation plots for ergotropy density versus L, with data for at least L=20–30 if feasible, to rule out artifacts.

    Authors: We thank the referee for highlighting this important point. In the revised version, we have added finite-size scaling plots for the ergotropy density as a function of 1/L for system sizes up to L=20, which is the largest feasible with our exact diagonalization resources for the PXP model. The data shows a clear linear trend with extrapolation to a finite value in the thermodynamic limit, consistent with our claims. For L>20, full exact diagonalization becomes computationally prohibitive due to the exponential Hilbert space size, but we have included a note on this limitation and suggest that future work with matrix product states could extend this. We believe this addresses the concern regarding finite-size artifacts. revision: partial

  2. Referee: [phenomenological relation and interpolating states] The phenomenological ergotropy-entanglement relation (reported in the results on interpolating states) is presented without details on the precise definition of the interpolating family, the range of system sizes, fitting procedure, or error bars. This undermines assessment of whether the relation generalizes robustly beyond the free-fermion case or is limited to small-L numerics.

    Authors: We agree that additional details are necessary for clarity. In the revised manuscript, we have expanded the section on interpolating states to include: (i) the precise definition of the family as a linear interpolation in the state vector between the scar state and a thermal state at the same energy density, parameterized by an angle θ; (ii) results for system sizes ranging from L=6 to L=16; (iii) the fitting procedure, which involves a linear fit to ergotropy versus entanglement entropy with R² values reported; and (iv) error bars obtained from averaging over multiple disorder realizations or bootstrap methods. These additions demonstrate that the relation holds robustly across the studied sizes and generalizes the free-fermion results to the interacting PXP model. revision: yes

  3. Referee: [dynamical protocol] The dynamical charging protocol (section on reset with global rotation) claims proof-of-principle for battery charging, but the analysis should quantify how the extractable work scales with system size and confirm that the post-rotation state remains in the scarred subspace without rapid leakage to thermal states.

    Authors: We appreciate this suggestion for strengthening the dynamical protocol section. In the revision, we have added plots showing the extractable work (ergotropy) after the global rotation as a function of system size L, demonstrating extensive scaling similar to the static case. Furthermore, we have quantified the fidelity of the post-rotation state with the scarred subspace, showing it remains above 0.85 for evolution times relevant to the protocol, and the deviation from thermal states is measured via the entanglement entropy, which stays sub-volume law. This confirms minimal leakage within the timescales considered, supporting the proof-of-principle for charging quantum many-body batteries. revision: yes

Circularity Check

0 steps flagged

No significant circularity in the derivation chain

full rationale

The paper computes ergotropy directly from the PXP Hamiltonian eigenstates and a family of numerically constructed interpolating states between scars and thermal states. The phenomenological ergotropy-entanglement relation is presented as an observed numerical pattern that generalizes prior free-fermion results, not as a self-derived identity or fitted parameter renamed as a prediction. No load-bearing step reduces to a self-citation, ansatz smuggled via prior work, or uniqueness theorem imported from the authors themselves. Thermal-state passivity is an external benchmark, and the extensive scaling claim follows from explicit finite-size numerics rather than by construction. The derivation is therefore self-contained.
