Correlated Metals, Metamagnetism, and Orbital Nematic Order in moiré Materials with Neural Quantum States
Wei Zhang, Ataç İmamoğlu, Tao Shi +2
In this work, we investigate a continuum model of two-dimensional electrons interacting via long-range Coulomb forces and subject to a triangular periodic potential at filling fact…
Scalable Simulation of Strongly Correlated Electron-Phonon Systems via Non-Gaussian Matrix Product States
Siyuan Jiang, Tao Shi
We investigate strongly correlated electron-phonon (e-ph) systems via a non-Gaussian matrix product state method. By combining non-Gaussian states with matrix product states, our m…
Phase diagram of the single-flavor Gross--Neveu--Wilson model from the Grassmann corner transfer matrix renormalization group
Jian-Gang Kong, Shinichiro Akiyama, Tao Shi +1
We investigate the phase structure of the single-flavor Gross--Neveu model with Wilson fermions using the Grassmann corner transfer matrix renormalization group (CTMRG). The path i…
Variational approach to the dynamics of dissipative quantum impurity models
Yi-Fan Qu, Martino Stefanini, Tao Shi +4
Recent experiments with quantum simulators using ultracold atoms and superconducting qubits have demonstrated the potential of controlled dissipation as a versatile tool for realiz…
Spin-Holstein models in trapped-ion systems
Johannes Knörzer, Tao Shi, Eugene Demler +1
In this work, we highlight how trapped-ion quantum systems can be used to study generalized Holstein models, and benchmark expensive numerical calculations. We study a particular s…
A variational approach for many-body systems at finite temperature
Tao Shi, Eugene Demler, J. Ignacio Cirac
We introduce a non-linear differential flow equation for density matrices that provides a monotonic decrease of the free energy and reaches a fixed point at the Gibbs thermal state…
Gaussian states for the variational study of (1+1)-dimensional lattice gauge models
P. Sala, T. Shi, S. Kühn +3
We introduce a variational ansatz based on Gaussian states for (1+1)-dimensional lattice gauge models. To this end we identify a set of unitary transformations which decouple the g…
Variational study of U(1) and SU(2) lattice gauge theories with Gaussian states in 1+1 dimensions
P. Sala, T. Shi, S. Kühn +3
We introduce a method to investigate the static and dynamic properties of both Abelian and non-Abelian lattice gauge models in 1+1 dimensions. Specifically, we identify a set of tr…
Solving quantum impurity problems in and out of equilibrium with variational approach
Yuto Ashida, Tao Shi, Mari Carmen Bañuls +2
A versatile and efficient variational approach is developed to solve in- and out-of-equilibrium problems of generic quantum spin-impurity systems. Employing the discrete symmetry h…
