Small amplitude collective modes of a finite-size unitary Fermi gas in deformed traps
Na Fei, Junchen Pei, Kai Wang +1
We have investigated collective breathing modes of a unitary Fermi gas in deformed harmonic traps. The ground state is studied by the Superfluid Local Density Approximation (SLDA)…

Nonreciprocal photon blockade in a two-mode cavity with a second-order nonlinearity
Kai Wang, Ya-Fei Yu, Zhi-Ming Zhang
It is shown that the Fizeau drag can be used to cause nonreciprocity. We propose the use of a nanostructured toroid cavity made of nonlinear materials to achieve nonrecip…
