Localization and criticality in antiblockaded 2D Rydberg atom arrays
Fangli Liu, Zhi-Cheng Yang, Przemyslaw Bienias +2
Controllable Rydberg atom arrays have provided new insights into fundamental properties of quantum matter both in and out of equilibrium. In this work, we study the effect of exper…
Realizing and Probing Baryonic Excitations in Rydberg Atom Arrays
Fangli Liu, Seth Whitsitt, Przemyslaw Bienias +2
We propose a realization of mesonic and baryonic quasiparticle excitations in Rydberg atom arrays with programmable interactions. Recent experiments have shown that such systems po…
Hilbert-Space Fragmentation from Strict Confinement
Zhi-Cheng Yang, Fangli Liu, Alexey V. Gorshkov +1
We study one-dimensional spin-1/2 models in which strict confinement of Ising domain walls leads to the fragmentation of Hilbert space into exponentially many disconnected subspace…
Real-time dynamics of string breaking in quantum spin chains
Roberto Verdel, Fangli Liu, Seth Whitsitt +2
String breaking is a central dynamical process in theories featuring confinement, where a string connecting two charges decays at the expense of the creation of new particle-antipa…
Momentum-space entanglement after a quench in one-dimensional disordered fermionic systems
Rex Lundgren, Fangli Liu, Pontus Laurell +1
We numerically investigate the momentum-space entanglement entropy and entanglement spectrum of the random-dimer model and its generalizations, which circumvent Anderson localizati…
Circuit Complexity across a Topological Phase Transition
Fangli Liu, Seth Whitsitt, Jonathan B. Curtis +5
We use Nielsen's geometric approach to quantify the circuit complexity in a one-dimensional Kitaev chain across a topological phase transition. We find that the circuit complexitie…
Confined Quasiparticle Dynamics in Long-Range Interacting Quantum Spin Chains
Fangli Liu, Rex Lundgren, Paraj Titum +4
We study the quasiparticle excitation and quench dynamics of the one-dimensional transverse-field Ising model with power-law () interactions. We find that long-range interac…
Asymmetric Particle Transport and Light-Cone Dynamics Induced by Anyonic Statistics
Fangli Liu, James R. Garrison, Dong-Ling Deng +2
We study the non-equilibrium dynamics of Abelian anyons in a one-dimensional system. We find that the interplay of anyonic statistics and interactions gives rise to spatially asymm…
Directional excitation of graphene surface plasmons
Fangli Liu, Cheng Qian, Y. D. Chong
We propose a scheme to directionally couple light into graphene plasmons by placing a graphene sheet on a magneto-optical substrate. When a magnetic field is applied parallel to th…
Localization and adiabatic pumping in a generalized Aubry-André-Harper model
Fangli Liu, Somnath Ghosh, Y. D. Chong
A generalization of the Aubry-André-Harper (AAH) model is developed, containing a tunable phase shift between on-site and off-diagonal modulations. A localization transition can be…
Gate-tunable coherent perfect absorption of terahertz radiation in graphene
Fangli Liu, Y. D. Chong, Shaffique Adam +1
Perfect absorption of radiation in a graphene sheet may play a pivotal role in the realization of technologically relevant optoelectronic devices. In particular, perfect absorption…
