Ward-Takahashi Identity and Gauge-Invariant Response Theory for Open Quantum Systems
Hongchao Li, Xie-Hang Yu, Masaya Nakagawa +1
We derive the Ward-Takahashi identity and establish the gauge-invariant response theory for open quantum systems described by Lindbladians to show that particle-number conservation…
Optimizing digital quantum simulation of open quantum lattice models
Xie-Hang Yu, Hongchao Li, J. Ignacio Cirac +1
Many-body systems arising in condensed matter physics and quantum optics inevitably couple to the environment and need to be modelled as open quantum systems. While near-optimal al…
A Lieb-Robinson bound for open quantum systems with memory
Rahul Trivedi, Xiehang Yu, Mark Rudner
We consider a general class of spatially local non-Markovian open quantum lattice models, with a bosonic environment that is approximated as Gaussian. Under the assumption of a fin…
Dissipative Superfluidity in a Molecular Bose-Einstein Condensate
Hongchao Li, Xie-Hang Yu, Masaya Nakagawa +1
Motivated by recent experimental realization of a Bose-Einstein condensate (BEC) of dipolar molecules, we develop superfluid transport theory for a dissipative BEC to show that a w…
Dual-isometric Projected Entangled Pair States
Xie-Hang Yu, J. Ignacio Cirac, Pavel Kos +1
Efficient characterization of higher dimensional many-body physical states presents significant challenges. In this paper, we propose a new class of Project Entangled Pair State (P…
Hierarchical generalization of dual unitarity
Xie-Hang Yu, Zhiyuan Wang, Pavel Kos
Quantum dynamics with local interactions in lattice models display rich physics, but is notoriously hard to study. Dual-unitary circuits allow for exact answers to interesting phys…
