Variable detuning in Rydberg arrays induces strong Hilbert-space fragmentation whose fragment dimensions exhibit multiple scaling behaviors, with emergent kinetic constraints captured by an auxiliary fermion description.
Quench dynamics in three-level dipole-interacting Rydberg arrays produce scalable spin-nematic squeezing with ξ² ∝ N^{-2/3} (all-to-all symmetric) or N^{-0.7} (antisymmetric), yielding F_Q ∝ N².
Magnetic fields tune the XXZ anisotropy parameter in alkaline-earth Rydberg pairs, allowing a folded XXZ model in ytterbium without fine-tuning and a mean-field supersolid on the square lattice.
Long-range interactions in the spin-one Heisenberg chain with anisotropy stabilize continuous symmetry breaking phases with logarithmic corrections to entanglement entropy and continuously varying critical exponents.
A scheme is developed to engineer strong three-body interactions in Rydberg atom lattices, allowing the effective Hamiltonian and emergent quantum phases to be modified compared to two-body-only systems.
A 256-qubit Rydberg simulator quantitatively reproduces the magnetization curves and antiferromagnetic transition of TmMgGaO4 while revealing thermalization after quenches.
Quantum quenches in the Ising chain exhibit qualitatively distinct out-of-equilibrium dynamics when crossing continuous versus first-order quantum transitions depending on the transverse field strength.
Light-induced losses dominate DyK Feshbach molecule decay in most near-IR traps, but near 2000 nm collisional losses appear and are suppressed by an order of magnitude for the most weakly bound dimers due to Pauli exclusion.
Tuning a femtosecond laser across the two-photon ionization threshold controls the formation of dense Rydberg gas or ultracold plasma in a Rb BEC, with charge imbalance driving the decay as confirmed by electron measurements and simulations.
In Markovian open quantum systems with bistability, noise-induced stochastic switching limits relaxation and follows an Arrhenius law with inverse system size as effective temperature, distinct from deterministic slow relaxation due to a small Liouvillian gap.
