Efficient variational approach to the Fermi polaron problem in two dimensions, both in and out of equilibrium
Yi-Fan Qu, Pavel E. Dolgirev, Eugene Demler +1
We develop a non-Gaussian variational approach that enables us to study both equilibrium and far-from-equilibrium physics of the two-dimensional Fermi polaron. This method provides…

Emergence of a sharp quantum collective mode in a one-dimensional Fermi polaron
Pavel E. Dolgirev, Yi-Fan Qu, Mikhail B. Zvonarev +2
The Fermi-polaron problem of a mobile impurity interacting with fermionic medium emerges in various contexts, ranging from the foundations of Landau's Fermi-liquid theory to electr…

Three photon absorption in ZnO and ZnS crystals
Jun He, Yingli Qu, Heping Li +2
We report a systematic investigation of both three-photon absorption (3PA)spectra and wavelength dispersions of Kerr-type nonlinear refraction in wide-gap semiconductors. The Z-sca…
