Proposal for Observing Yang-Lee Criticality in Rydberg Atomic Arrays
Ruizhe Shen, Tianqi Chen, Mohammad Mujahid Aliyu +4
Yang-Lee edge singularities (YLES) are the edges of the partition function zeros of an interacting spin model in the space of complex control parameters. They play an important rol…
High-fidelity realization of the AKLT state on a NISQ-era quantum processor
Tianqi Chen, Ruizhe Shen, Ching Hua Lee +1
The AKLT state is the ground state of an isotropic quantum Heisenberg spin- model. It exhibits an excitation gap and an exponentially decaying correlation function, with fractio…
Thermodynamic performance of a periodically driven harmonic oscillator correlated with the baths
Tianqi Chen, Dario Poletti
We consider a harmonic oscillator under periodic driving and coupled to two harmonic-oscillator heat baths at different temperatures. We use the thermofield transformation with cha…
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…
Skyrmion quantum spin Hall effect
Tianqi Chen, Tim Byrnes
The quantum spin Hall effect is conventionally thought to require a strong spin-orbit coupling, producing an effective spin-dependent magnetic field. However, spin currents can als…
