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…
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…
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…
