Bond Bipolarons: Sign-free Monte Carlo Approach
Chao Zhang, Nikolay V. Prokof'ev, Boris V. Svistunov
Polarons originating from phonon displacement modulated hopping have relatively light masses and, thus, are of significant current interest as candidates for bipolaron mechanism of…
Peierls/Su-Schrieffer-Heeger polarons in two dimensions
Chao Zhang, Nikolay V. Prokof'ev, Boris V. Svistunov
Polarons with different types of electron-phonon coupling have fundamentally different properties. When the dominant interaction is between the electron density and lattice displac…
The effect of disorder on the phase diagrams of hard-core lattice bosons with cavity-mediated long-range and nearest-neighbor interactions
Chao Zhang, Heiko Rieger
We use quantum Monte Carlo simulations with the worm algorithm to study the phase diagram of a two-dimensional Bose-Hubbard model with cavity-mediated long-range interactions and u…
Phase diagrams of the disordered Bose-Hubbard model with cavity-mediated long-range and nearest-neighbor interactions
Chao Zhang, Heiko Rieger
Recent experiments with ultracold atoms in an optical lattice have realized cavity-mediated long-range interaction and observed the emergence of a supersolid phase and a density wa…
A quantum model for the stock market
Chao Zhang, Lu Huang
Beginning with several basic hypotheses of quantum mechanics, we give a new quantum model in econophysics. In this model, we define wave functions and operators of the stock market…
Stability of Metallic Structure in Compressed Solid GeH4
Chao Zhang, Yanling Li, Xiaojia Chen +2
We study the electronic and lattice dynamical properties of compressed solid germane in the pressure range up to 200 GPa with density functional theory. A stable metallic structure…
