Algebraic closure from local constraints stabilizes su(3) scar subspaces with non-equally-spaced multidirectional spectra and multifrequency oscillations, independent of exact solvability.
Neural quantum states with a tailored 3D convolutional architecture simulate quench dynamics up to 1000 qubits and verify the 3D quantum Kibble-Zurek mechanism with RG-derived logarithmic corrections and data collapse.
Finite-temperature energy transport in the PXP model exhibits a crossover from single-magnon coherent dynamics to superdiffusive hydrodynamics with activated damping time separating the regimes.
At special drive frequencies, the leading perturbative Floquet Hamiltonian of a driven Rydberg chain maps to the XXZ model, producing emergent prethermal integrability confirmed by level statistics and entanglement in exact diagonalization.
Rydberg atoms on a triangular lattice host a deconfined quantum critical point between 1/3 and 2/3 filling phases, with predicted critical exponents, emergent U(1) symmetry in a CFT, and numerical confirmation.
Experiments, numerics, and analytics on Rydberg atoms in a Lieb lattice reveal density-wave phases including a fluctuation-stabilized collinear order, a quantum liquid-vapor transition with hysteresis, and kinetically constrained slow relaxation after quenches.
Foundry-produced Si3N4 waveguides achieve >50 dB optical crosstalk reduction for addressing an eight-ion chain of Ba-138 with lasers at 493 nm, 585 nm, and 650 nm.
A mapping of the Z3 Rabi model to a qubit-boson ring enables superconducting implementations and a coupled chain for the Z3 Potts model.
Random global pulses in Rydberg chains generate states with Haar-like statistics at long times for weak interactions, while optimal control prepares generic symmetric states with infidelities from 10^{-5} to 3e-2 for 9 spins, worsening with entanglement entropy.
TDVP-MPS simulations of Rydberg atom chains mitigate exponential concentration in QELM, yielding competitive MNIST accuracy via controlled entanglement and disorder without requiring exact quantum dynamics.

Quantum criticality and nonequilibrium dynamics on a Lieb lattice of Rydberg atoms
Experiments, numerics, and analytics on Rydberg atoms in a Lieb lattice reveal density-wave phases including a fluctuation-stabilized collinear order, a quantum liquid-vapor transition with hysteresis, and kinetically constrained slow relaxation after quenches.
