Signatures of many-body localization and metastability by weak perturbation
Yang Zhao, Rajesh Narayanan, Jaeyoon Cho
Nonequilibrium dynamics in isolated quantum many-body systems displays a number of intriguing features, such as many-body localization (MBL) and prethermalization. Here we investig…
Correlations in local measurements and entanglement in many-body systems
Chae-Yeun Park, Jaeyoon Cho
While entanglement plays an important role in characterizing quantum many-body systems, it is hardly possible to directly access many-body entanglement in real experiments. In this…
Quantum Phase Transition and Entanglement in Topological Quantum Wires
Jaeyoon Cho, Kun Woo Kim
We investigate the quantum phase transition of the Su-Schrieffer-Heeger (SSH) model by inspecting the two-site entanglements in the ground state. It is shown that the topological p…
Realistic Area-Law Bound on Entanglement from Exponentially Decaying Correlations
Jaeyoon Cho
A remarkable feature of typical ground states of strongly-correlated many-body systems is that the entanglement entropy is not an extensive quantity. In one dimension, there exists…
Sufficient Condition for Entanglement Area Laws in Thermodynamically Gapped Spin Systems
Jaeyoon Cho
We consider general locally-interacting arbitrary-dimensional lattice spin systems that are gapped for any system size. We show under reasonable conditions that nondegenerate groun…
Emergence of stationary many-body entanglement in driven-dissipative Rydberg lattice gases
S. K. Lee, J. Cho, K. S. Choi
Non-equilibrium quantum dynamics represents an emerging paradigm for condensed matter physics, quantum information science, and statistical mechanics. Strongly interacting Rydberg…
