Microscopic Origin of Emergent Elliptic Flow and Molecule Formation in Strongly Interacting Quasi-Two-Dimensional Few-Body Systems
Xin-Yuan Gao, Kai Yuen Lee, Qingze Guan +1
Recent experiments simulating two-dimensional few-fermion systems have observed emergent hydrodynamic behavior, i.e., interaction-driven elliptic flow by adding fermions two at a t…
In-situ Observation of Magnetostriction Crossover in a Strongly Dipolar Two-Dimensional Bose Gas
Yifei He, Xin-Yuan Gao, Haoting Zhen +3
Magnetostriction, the anisotropic spatial deformation, is a hallmark of dipolar gases with strong long-range interactions, yet it poses a challenge for in-situ characterization. He…
Dynamical Phase Transition of Dissipative Fermionic Superfluids
Xin-Yuan Gao, Yangqian Yan
Driven-dissipative open quantum many-body systems exhibit rich phases that are characterized by the steady states in the long-time dynamics. However, lossy open systems inevitably…
Fate of thermalization of ultracold fermions with two-body dissipation
Xin-Yuan Gao, Yangqian Yan
Two-body dissipation due to chemical reactions occurs in both ultracold fermionic and bosonic molecular gases. Despite recent advances in achieving quantum degeneracy, the loss dyn…
Exact Thermodynamics For Weakly Interacting Normal-Phase Quantum Gases: Equations of State For All Partial Waves
Xin-Yuan Gao, D. Blume, Yangqian Yan
While the thermodynamics for bosonic systems with weak -wave interactions has been known for decades, a general and systematic extension to higher partial waves has not yet been…
Thermodynamics of Spin-Imbalanced Fermi Gases with SU(N) Symmetric Interaction
Chengdong He, Xin-Yuan Gao, Ka Kwan Pak +6
Thermodynamics of degenerate Fermi gases has been extensively studied through various aspects such as Pauli blocking effects, collective modes, BCS superfluidity, and more. Despite…
