Coupled dissipative time crystals show chaotic synchronization with positive Lyapunov exponents and high Pearson correlations in the classical limit, plus analogous staggered-to-uniform crossovers and GUE statistics in quantum trajectories.
Effective gain engineered through evaporative cooling of thermal atoms enables Bose-Einstein condensation in a topological edge state of a synthetic hyperfine SSH lattice, realizing a topological atom laser.
Phase diagrams and correlation asymptotics of two non-Hermitian XY chains depend on both the expectation-value formalism and the chosen eigenstate, favoring standard quantum mechanics.
Quantum jump correlations and waiting-time distributions in long-range dissipative spins display clear signatures of the paramagnetic-to-ferromagnetic transition when analyzed with tilted Lindbladian, cluster mean-field, and cumulant expansion methods.
New techniques for error-independent unified path variation, non-degenerate batched sampling, and flexible contraction accelerate tensor network quantum trajectory simulations by more than 10^8 times.
A tensor-network solver extended with jump-counting computes electron currents in up to 50 quantum dots, matching traditional solvers for small systems but with orders of magnitude less memory and time.
In a monitored Rashba chain the disconnected entanglement entropy stays topological for a time linear in system size because monitoring switches between degenerate topological states while poisoning other quasiparticles.
In a complex XY spin chain, left-right eigenstate distinctions yield static spin-correlation signatures and time-averaged entanglement-entropy differences that mark exceptional points in RT- and PT-symmetric regimes.
The Lindblad equation is valid only within a finite time window controlled by the timescales of the bath, the system, and the rotating-wave approximation, with failure at early and late times.
Quantum confinement in 2D hexagonal crystals like graphene and TMDs produces discrete electronic and excitonic spectra with strongly amplified interactions that enable correlated quantum states.
