Derives analytic FCS expression for emergent interaction between hard-core quantum strings, yielding entanglement-controlled asymptotic form lnΔE(r)∼−π²r²/(12S_ℓ) for the effective potential.
A single-particle dark state in a dissipating spin chain induces universal long-time many-body dynamics with momentum distribution scaling as k sqrt(t) and density decaying as 1/(sqrt(t) log t).
Introduces and tests a finite-volume scheme enabling stable continuum extrapolation of the step-scaling function in (2+1)D Hamiltonian U(1) gauge theory via matrix product states.
A quantum simulation framework is developed and demonstrated for energy loss and hadronization of a heavy quark in 1+1D SU(2) lattice gauge theory on 18 qubits of IBM hardware, with results matching classical simulations.
Numerical iPEPS with loop expansions indicates the SU(4) Heisenberg model on the hyperhoneycomb lattice has a gapless quantum spin-liquid ground state, consistent with prior variational Monte Carlo results.
Numerical study demonstrates controlled transport of Z4 parafermion edge states in a ladder model and quantifies the adiabatic speed limit under realistic conditions.
In the topological regime of a parametrically modulated spin-1/2 chain, time-averaged magnetization shows no frequency dispersion and spatial correlations are absent or suppressed near resonance, with the topological-to-trivial transition set by modulation frequency.
Systematic numerical study of QAOA parameter transfer on heavy-hex Ising models with local cubic terms shows transferred angles from small instances yield improving expectation values up to 49 layers on instances up to 156 qubits, with hardware runs confirming gains up to p=10.
Using iMPS time evolution, the authors demonstrate photoinduced long-range η-pairing in the thermodynamic limit of driven Mott insulators for optimal laser parameters, linked to an insulator-to-metal transition in time-dependent spectra.
