The transverse field in the quantum Ising chain is linearly ramped from the parato the ferromagnetic phase across the quantum critical point at a rate characterized by a quench time τQ. We calculate a connected kinkkink correlator in the final state at zero transverse field. The correlator is a sum of two terms: a negative (anti-bunching) Gaussian that depends on the Kibble-Zurek (KZ) correlation length only and a positive term that depends on a second longer scale of length. The second length… Expand

Dynamics and correlations at a quantum phase transition beyond Kibble-Zurek
When a quantum phase transition is traversed by tuning a parameter of a Hamiltonian, Kibble-Zurek (KZ) theory stands out as the most robust theory of defect generation in such a process. We show howExpand

Quantum phases of matter on a 256-atom programmable quantum simulator.
TLDR
This work demonstrates a programmable quantum simulator based on deterministically prepared two-dimensional arrays of neutral atoms, featuring strong interactions controlled by coherent atomic excitation into Rydberg states, and realizes a quantum spin model with tunable interactions for system sizes ranging from 64 to 256 qubits.

Quantum simulation of 2D antiferromagnets with hundreds of Rydberg atoms.
TLDR
This work uses programmable arrays of individual atoms trapped in optical tweezers, with interactions controlled by laser excitation to Rydberg states, to implement an iconic many-body problem-the antiferromagnetic two-dimensional transverse-field Ising model, and demonstrates that this platform can be readily used to address open questions in many- body physics.

Adiabatic dynamics of quasiperiodic transverse Ising model
We study the non-equilibrium dynamics due to slowly taking a quasiperiodic Hamiltonian across its quantum critical point. The special quasiperiodic Hamiltonian that we study here has two differentExpand

Quantum Kibble–Zurek mechanism and critical dynamics on a programmable Rydberg simulator
TLDR
A Rydberg atom quantum simulator with programmable interactions is used to experimentally verify the quantum Kibble–Zurek mechanism through the growth of spatial correlations during quantum phase transitions, and is subsequently used to measure the critical exponents associated with chiral clock models.
