Summary: This study investigates the nonequilibrium imaginary-time dynamics of the deconfined quantum critical point (DQCP) in the two-dimensional J-Q3 model. It finds that the spinon confinement length increases proportionally to time, rather than the usual correlation length. Additionally, it discovers that the order parameters of the Neel and the valence-bond-solid orders can be controlled by different length scales, although they satisfy the same equilibrium scaling forms. A dual dynamic scaling theory is proposed. These findings not only contribute to a new understanding of nonequilibrium criticality in DQCP, but also provide a controllable method for studying dynamics in strongly correlated systems.

Summary: In this study, we demonstrate for the first time the breakdown of ergodicity in d-dimensional Ising models with a weak transverse field in a prethermal regime. We show that the novel Hilbert-space fragmentation occurs as a consequence of the emergent global conservation law of the domain wall number in the effective nonintegrable model with d >= 2.

Summary: This article investigates the nonequilibrium evolution of coexisting ferromagnetic domains in the two-dimensional quantum Ising model, demonstrating the use of a holographic mapping to study the quantum-fluctuating interface and the emergence of robust ergodicity breaking in two dimensions due to a symmetry-breaking longitudinal field.

Summary: We discuss the quantum dynamics in the transverse field Ising model in two dimensions and show that the Hilbert space shatters into dynamically disconnected subsectors up to a quantified prethermal timescale. This shattering arises from the interplay of a U(1) conservation law and a one-form Z2 constraint. The number of disconnected subsectors is exponential in system volume, and a subspace with exponential growth within the system volume exhibits exactly localized dynamics.

Summary: The study investigates the nonequilibrium imaginary-time relaxation dynamics in the J-Q2 model, confirming the universality of the dual dynamic scaling at the critical point and exploring the breakdown and vestige of the dual dynamic scaling away from the critical point. The findings are important for possible experimental realizations in quantum computers.

Summary: The discovery of topological order revolutionized the understanding of quantum matter and laid the theoretical groundwork for quantum error-correcting codes. By preparing the ground state of the toric code Hamiltonian on a superconducting quantum processor, researchers were able to measure topological entanglement entropy and simulate anyon interferometry. Investigating aspects of the surface code, including logical state injection and the decay of nonlocal order parameter, showed the potential of quantum processors in studying topological quantum matter and error correction mechanisms.

Summary: In this study, a nonlocal approximation method was developed to tackle the implementation challenges of quantum imaginary-time evolution method (QITE) on noisy intermediate-scale quantum (NISQ) devices. By removing the locality condition, the quantum circuit depth was significantly reduced. The extended LA (eLA) and nonlocal approximation (NLA) methods require fewer circuit depths than the local approximation (LA) to achieve the same level of computational accuracy.
