Elementary excitations in an integrable twisted J1-J2 spin chain in the thermodynamic limit
Wei Wang, Yi Qiao, Rong-Hua Liu +2
The exact elementary excitations in a typical U(1) symmetry broken quantum integrable system, that is the twisted J1-J2 spin chain with nearest-neighbor, next nearest neighbor and…
Exact ground state and elementary excitations of a competing spin chain with twisted boundary condition
Wei Wang, Yi Qiao, Junpeng Cao +2
A novel Bethe ansatz scheme is proposed to investigate the exact physical properties of an integrable anisotropic quantum spin chain with competing interactions among the nearest,…
Phase diagram of the spin-1/2 Yukawa-SYK model: Non-Fermi liquid, insulator, and superconductor
Wei Wang, Andrew Davis, Gaopei Pan +2
We analyze the phase diagram of the Yukawa-Sachdev-Ye-Kitaev model, which describes complex fermions randomly interacting with real bosons via a Yukawa coupling, at finite temperat…
Confinement transition in the QED-Gross-Neveu-XY universality class
Lukas Janssen, Wei Wang, Michael M. Scherer +2
The coupling between fermionic matter and gauge fields plays a fundamental role in our understanding of nature, while at the same time posing a challenging problem for theoretical…
Permutation cycles of hardcore Bose-Hubbard models on square and Kagome lattices
Liana Shpani, Fabio Lingua, Wei Wang +1
In this paper, we study the statistics of permutation cycles of ground-state hardcore lattice bosons described by various two-dimensional Bose-Hubbard-type models on both square an…
Designer Monte Carlo Simulation for Gross-Neveu Transition
Yuzhi Liu, Wei Wang, Kai Sun +1
In this manuscript, we study quantum criticality of Dirac fermions via large-scale numerical simulations, focusing on the Gross-Neveu-Yukawa(GNY) chiral-Ising quantum critical poin…
Dynamics of Compact Quantum Electrodynamics at Large Fermion Flavor
Wei Wang, Da-Chuan Lu, Xiao Yan Xu +2
Thanks to the development in quantum Monte Carlo technique, the compact U(1) lattice gauge theory coupled to fermionic matter at (2+1)D is now accessible with large-scale numerical…
Braiding properties of worldline configurations in hardcore lattice bosons
Fabio Lingua, Wei Wang, Liana Shpani +1
In this manuscript, we study braiding properties of worldline configurations for a variety of ground-states of hardcore Bose-Hubbard models in two dimensions. Configurations are co…
Inter-species entanglement of Bose-Bose mixtures trapped in optical lattices
Wei Wang, Vittorio Penna, Barbara Capogrosso-Sansone
In the present work we discuss inter-species entanglement in Bose-Bose mixtures trapped in optical lattices. This work is motivated by the observation that, in the presence of a se…
Analysis and resolution of the ground-state degeneracy of the two-component Bose-Hubbard model
Wei Wang, Vittorio Penna, Barbara Capogrosso-Sansone
We study the degeneracy of the ground-state energy of the two-component Bose-Hubbard model and of the perturbative correction . We show that the degeneracy properties of $…
