Entanglement Steering in Adaptive Circuits with Feedback
Vikram Ravindranath, Yiqiu Han, Zhi-Cheng Yang +1
The intensely studied measurement-induced entanglement phase transition has become a hallmark of non-unitary quantum many-body dynamics. Usually, such a transition only shows up at…
Hydrodynamic theory of scrambling in chaotic long-range interacting systems
Tianci Zhou, Andrew Y. Guo, Shenglong Xu +2
The Fisher-Kolmogorov-Petrovsky-Piskunov (FKPP) equation provides a mean-field theory of out-of-time-ordered commutators in locally interacting quantum chaotic systems at high ener…
Entanglement phase transitions in random stabilizer tensor networks
Zhi-Cheng Yang, Yaodong Li, Matthew P. A. Fisher +1
We explore a class of random tensor network models with "stabilizer" local tensors which we name Random Stabilizer Tensor Networks (RSTNs). For RSTNs defined on a two-dimensional s…
Quantum criticality in the nonunitary dynamics of -dimensional free fermions
Qicheng Tang, Xiao Chen, W. Zhu
We explore the nonunitary dynamics of -dimensional free fermions and show that the obtained steady state is critical regardless the strength of the nonunitary evolution. Num…
Entanglement Negativity at Measurement-Induced Criticality
Shengqi Sang, Yaodong Li, Tianci Zhou +3
We propose entanglement negativity as a fine-grained probe of measurement-induced criticality. We motivate this proposal in stabilizer states, where for two disjoint subregions, co…
Hydrodynamics in lattice models with continuous non-Abelian symmetries
Paolo Glorioso, Luca V. Delacrétaz, Xiao Chen +2
We develop a systematic effective field theory of hydrodynamics for many-body systems on the lattice with global continuous non-Abelian symmetries. Models with continuous non-Abeli…
Quantum butterfly effect in polarized Floquet systems
Xiao Chen, Rahul M. Nandkishore, Andrew Lucas
We explore quantum dynamics in Floquet many-body systems with local conservation laws in one spatial dimension, focusing on sectors of the Hilbert space which are highly polarized.…
Measurement-driven entanglement transition in hybrid quantum circuits
Yaodong Li, Xiao Chen, Matthew P. A. Fisher
In this paper we continue to explore "hybrid" quantum circuit models in one-dimension with both unitary and measurement gates, focussing on the entanglement properties of wavefunct…
Quantum chaos dynamics in long-range power law interaction systems
Xiao Chen, Tianci Zhou
We use out-of-time-order commutator (OTOC) to diagnose the propagation of chaos in one dimensional long-range power law interaction system. We map the evolution of OTOC to a classi…
Measuring the distance between quantum many-body wave functions
Xiao Chen, Tianci Zhou, Cenke Xu
We study the distance of two wave functions under chaotic time evolution. The two initial states are differed only by a local perturbation. To be entitled "chaos" the distance shou…
Entanglement Entropy and Mutual Information of Circular Entangling Surfaces in 2 + 1-dimensional Quantum Lifshitz Model
Tianci Zhou, Xiao Chen, Thomas Faulkner +1
We investigate the entanglement entropy (EE) of circular entangling cuts in the 2+1-dimensional quantum Lifshitz model, whose ground state wave function is a spatially conformal in…
