Generalized master equation for driven quantum oscillators: microscopic origin of nonlinear dissipation and asymmetric resonances
Jakob Wagner, Jeff Maki, Oded Zilberberg +1
Driven nonlinear quantum oscillators are a central platform for quantum technologies, yet their dissipative dynamics are typically described using Lindblad or Caldeira-Leggett mast…
Effective Three-Boson Interactions using a Separable Potential
Corinne Beckers, Jacques Tempere, Jeff Maki +1
Effective field theories (EFTs) are widely used to study many-body systems by describing two-body interactions using zero-ranged contact potentials. However, when extended to three…
Persistent breather and dynamical symmetry in a unitary Fermi gas
Dali Sun, Jing Min, Xiangchuan Yan +8
SO(2,1) dynamical symmetry makes a remarkable prediction that the breathing oscillation of a scale invariant quantum gas in an isotropic harmonic trap is isentropic and can persist…
Emergent -wave interactions in orbitally active quasi-two-dimensional Fermi gases
Colin J. Dale, Kevin G. S. Xie, Kiera Pond Grehan +3
We investigate the scattering properties and bound states of a quasi-two-dimensional (q2D) spin-polarized Fermi gas near a -wave Feshbach resonance. Strong confinement promotes…
Radio-Frequency Spectroscopy and the Dimensional Crossover in Interacting Spin-Polarized Fermi Gases
Jeff Maki, Colin J. Dale, Joseph H. Thywissen +1
Low-dimensional ultracold gases are created in the laboratory by confining three-dimensional (3D) gases inside highly anisotropic trapping potentials. Such trap geometries not only…
