Transport of Vector Solitons in Spin-Dependent Nonlinear Thouless Pumps
Xuzhen Cao, Chunyu Jia, Ying Hu +1
In nonlinear topological physics, Thouless pumping of nonlinear excitations is a central topic, often illustrated by scalar solitons. Vector solitons, with the additional spin degr…
Dissipative Nonlinear Thouless Pumping of Temporal Solitons
Xuzhen Cao, Chunyu Jia, Ying Hu +1
The interplay between topology and soliton is a central topic in nonlinear topological physics. So far, most studies have been confined to conservative settings. Here, we explore T…
Cornwall-Jackiw-Tomboulis effective field theory to nonuniversal equation of state of an ultracold Bose gas
Yi Zhang, Zhaoxin Liang
The equation of state (EOS) serves as a cornerstone in elucidating the properties of quantum many-body systems. A recent highlight along this research line consists of the derivati…
Interaction-Induced Dimensional Crossover through Full 3D to 1D
Tao Yu, Xiaoran Ye, Zhaoxin Liang
The exploration of dimensional crossover carries profound fundamental significance, serving as a crucial bridge in comprehending the remarkable disparities observed in transitional…
Nonlinear Thouless Pumping of Solitons Across an Impurity
Xuzhen Cao, Chunyu Jia, Ying Hu +1
The nonlinear Thouless pumping is an exciting frontier of topological physics. While recent works have revealed the quantized motion of solitons in Thouless pumps, the interplay be…
Nonuniversal Equation of State of a Quasi-2D Bose Gas in Dimensional Crossover
Xiaoran Ye, Tao Yu, Zhaoxin Liang
Equation of state (EOS) for a pure two-dimensional (2D) Bose gas exhibits a logarithmic dependence on the s-wave scattering length [L. Salasnich, Phys. Rev. Lett. 118, 130402 (2017…
