Accelerating analysis of Boltzmann equations using Gaussian mixture models: Application to quantum Bose-Fermi mixtures
Pavel E. Dolgirev, Kushal Seetharam, Márton Kanász-Nagy +4
The Boltzmann equation is a powerful theoretical tool for modeling the collective dynamics of quantum many-body systems subject to external perturbations. Analysis of the equation…
Collective flow of fermionic impurities immersed in a Bose-Einstein Condensate
Zoe Z. Yan, Yiqi Ni, Alexander Chuang +5
Interacting mixtures of bosons and fermions are ubiquitous in nature. They form the backbone of the standard model of physics, provide a framework for understanding quantum materia…
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…
Non-Gaussian correlations imprinted by local dephasing in fermionic wires
Pavel E. Dolgirev, Jamir Marino, Dries Sels +1
We study the behavior of an extended fermionic wire coupled to a local stochastic field. Since the quantum jump operator is Hermitian and quadratic in fermionic operators, it rende…
