Complexity Inequalities for Quantum Subsystems

hep-th · 2026-06-18 · unverdicted · novelty 7.0

Defines tripartite complexity and complexity gap for three-subsystem states and reports that the gap has definite sign across holographic CV, Fisher-Rao, and Krylov measures, suggesting it as a building block for complexity inequalities.

q-Askey Deformations of Double-Scaled SYK

hep-th · 2026-05-13 · unverdicted · novelty 7.0 · 2 refs

q-Askey deformations of DSSYK produce transfer matrices from basic orthogonal polynomials whose chord numbers map to ER bridge lengths and signal geometric transitions with discrete spectra in sine dilaton gravity.

Quantum scars from holographic boson stars

hep-th · 2026-05-04 · unverdicted · novelty 7.0 · 2 refs

Mini-boson stars in AdS spacetime are proposed as holographic realizations of quantum scars, exhibiting chaotic spectra with integrable subsectors, anomalously low entanglement, and robust Krylov complexity revivals.

Krylov Subspace Dynamics as Near-Horizon AdS$_2$ Holography

hep-th · 2026-02-12 · unverdicted · novelty 7.0

In the continuum limit the discrete Krylov chain becomes a Klein-Gordon field in AdS2, with Lanczos growth rate α identified as πT, recovering the maximal chaos bound and requiring the Breitenlohner-Freedman bound for consistency.

Pseudorandom Dynamics in the SYK Model and Cryptographic Censorship in JT Gravity

hep-th · 2026-05-24 · unverdicted · novelty 6.0

SYK disorder is shown to be an approximate unitary k-design for poly(N) k; under the planted-SYK hardness conjecture this yields gravitationally pseudorandom unitaries, implying cryptographic censorship in JT gravity with the regularized maximal geodesic length as distinguisher.

Complexity and Operator Growth in Holographic 6d SCFTs

hep-th · 2026-03-10 · unverdicted · novelty 6.0

In holographic 6d N=(1,0) SCFTs, generalized proper momentum of infalling particles grows linearly at late times, with early dynamics modified by SU(2)_R charge and quiver spreading.

Toward Krylov-based holography in double-scaled SYK

hep-th · 2025-10-26 · unverdicted · novelty 6.0

Establishes a threefold duality linking Krylov complexity growth rate to wormhole velocity and proper momentum in DSSYK holography, with higher moments capturing replica wormholes and Krylov entropy equaling parent-geometry von Neumann entropy after tracing baby universes.

Searching for emergent spacetime in spin glasses

hep-th · 2025-10-23 · unverdicted · novelty 6.0

Spectral functions of SYK, p-spin, and SU(M) Heisenberg models show exponential tails in spin-glass phases and quasiparticle families in spin-liquid phases, with a proof that exponential decay blocks detection of bulk causal structure.

Spacetime from Operator Algebras

hep-th · 2026-06-09 · unverdicted · novelty 5.0

Reconstructs spacetime metric, curvature, and Einstein equations from matter field operator algebras in the G to 0 limit without using Bekenstein-Hawking area law, then models finite-N discrete spectra via random matrix completion of enlarged type III algebras.

Krylov complexity has it all

hep-th · 2026-05-27 · unverdicted · novelty 5.0

Krylov complexity is equivalent to Lanczos coefficients, return amplitude, and spectral density for operator dynamics, via an explicit recursive algorithm from its t=0 Taylor expansion.

Krylov Complexity in Periodically Driven CFTs and Critical Fermions

hep-th · 2026-05-25 · unverdicted · novelty 5.0

Arnoldi coefficients approach unity exponentially in heating phases of driven CFTs but oscillate in non-heating phases; lattice realizations show distinct spectral and graph signatures despite similar CFT Krylov growth.

Probing the Chaos to Integrability Transition in Double-Scaled SYK

hep-th · 2026-01-14 · unverdicted · novelty 5.0

A first-order phase transition in the Berkooz-Brukner-Jia-Mamroud interpolating model causes chord number, Krylov complexity, and operator size to switch discontinuously from chaotic (linear/exponential) to quasi-integrable (quadratic) growth.
