Steady state quantum transport through an anharmonic oscillator strongly coupled to two heat reservoirs
Tianqi Chen, Vinitha Balachandran, Chu Guo +1
We investigate the transport properties of an anharmonic oscillator, modeled by a single-site Bose-Hubbard model, coupled to two different thermal baths using the numerically exact…

Effects of staggered Dzyaloshinskii-Moriya interactions in a quasi-two-dimensional Shastry-Sutherland model
Tianqi Chen, Chu Guo, Pinaki Sengupta +1
Frustrated quantum spin systems exhibit exotic physics induced by external magnetic field with anisotropic interactions. Here, we study the effect of non-uniform Dzyaloshinskii-Mor…
