Induced interactions in dilute atomic gases and liquid helium mixtures
Zhenhua Yu, C. J. Pethick
In dilute mixtures of two atomic gases, interactions between two minority atoms acquire a contribution due to interaction with the majority component. Using thermodynamic arguments…
Short range asymptotic behavior of the wave-functions of interacting spin-half fermionic atoms with spin-orbit coupling: a model study
Yuxiao Wu, Zhenhua Yu
We consider spin-half fermionic atoms with isotropic Rashba spin-orbit coupling in three directions. The interatomic potential is modeled by a square well potential. We derive the…
Itinerant Ferromagnetism in a polarized two-component Fermi gas
Pietro Massignan, Zhenhua Yu, Georg M. Bruun
We analyze when a repulsively interacting two-component Fermi gas becomes thermodynamically unstable against phase separation. We focus on the strongly polarised limit where the fr…
Multi-Sensor Fusion-Based Mobile Manipulator Remote Control for Intelligent Smart Home Assistance
Xiao Jin, Bo Xiao, Huijiang Wang +2
This paper proposes a wearable-controlled mobile manipulator system for intelligent smart home assistance, integrating MEMS capacitive microphones, IMU sensors, vibration motors, a…
Spin-correlation functions in ultracold paired atomic-fermion systems: sum rules, self-consistent approximations, and mean fields
Zhenhua Yu, Gordon Baym
The spin response functions measured in multi-component fermion gases by means of rf transitions between hyperfine states are strongly constrained by the symmetry of the interatomi…
Interaction effects on -symmetry breaking transition in atomic gases
Ziheng Zhou, Zhenhua Yu
Non-Hermitian systems having parity-time () symmetry can undergo a transition, spontaneously breaking the symmetry. Ultracold atomic gases provide an ideal platform…
