Self-consistent effective field theory to nonuniversal Lee-Huang-Yang term in quantum droplets
Yi Zhang, Xiaoran Ye, Ziheng Zhou +1
Quantum droplets (QDs) in weakly interacting ultracold quantum gases are typically characterized by mean-field theories incorporating Lee-Huang-Yang (LHY) quantum fluctuations unde…
Tuning spin-density separation via finite-range interactions: Dimensionality-driven signatures in dynamic structure factors
Xiaoran Ye, Yi Zhang, Ziheng Zhou +1
Spin-density (charge) separation, marked by distinct propagation velocities of spin and density excitations, epitomizes strong correlations, historically confined to one-dimensiona…
Probing -wave effects in spin-density separation of Bose mixtures with the dynamic structure factor
Xiaoran Ye, Zhaoxin Liang
Quantum mixtures of Bose gases with tunable - and -wave interactions offer a versatile platform to explore strongly correlated phases and exotic phenomena. While repulsive in…
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…
