Maximum Energy Growth Rate in Dilute Quantum Gases
Ran Qi, Zhe-yu Shi, Hui Zhai
In this letter we study how fast the energy density of a quantum gas can increase in time, when the inter-atomic interaction characterized by the -wave scattering length $a_\tex…
Radio-frequency response and contact of impurities in a quantum gas
Weizhe Edward Liu, Zhe-Yu Shi, Jesper Levinsen +1
We investigate the radio-frequency spectroscopy of impurities interacting with a quantum gas at finite temperature. In the limit of a single impurity, we show using Fermi's golden…
Theory of radio-frequency spectroscopy of impurities in quantum gases
Weizhe Edward Liu, Zhe-Yu Shi, Meera M. Parish +1
We present a theory of radio-frequency spectroscopy of impurities interacting with a quantum gas at finite temperature. By working in the canonical ensemble of a single impurity, w…
Dynamical Fractal in Quantum Gases with Discrete Scaling Symmetry
Chao Gao, Hui Zhai, Zhe-Yu Shi
Inspired by the similarity between the fractal Weierstrass function and quantum systems with discrete scaling symmetry, we establish general conditions under which the dynamics of…
Few-body states of bosons interacting with a heavy quantum impurity
Shuhei M. Yoshida, Zhe-Yu Shi, Jesper Levinsen +1
We consider the problem of a fixed impurity coupled to a small number of non-interacting bosons. We focus on impurity-boson interactions that are mediated by a closed-channel m…
Impurity-induced multi-body resonances in a Bose gas
Zhe-Yu Shi, Shuhei M. Yoshida, Meera M. Parish +1
We investigate the problem of identical bosons that are coupled to an impurity particle with infinite mass. For non-interacting bosons, we show that a dynamical impurity-boson…
