Theory of excitation of Rydberg polarons in an atomic quantum gas
R. Schmidt, J. D. Whalen, R. Ding +8
We present a quantum many-body description of the excitation spectrum of Rydberg polarons in a Bose gas. The many-body Hamiltonian is solved with functional determinant theory, and…
Creation of Rydberg Polarons in a Bose Gas
F. Camargo, R. Schmidt, J. D. Whalen +8
We report spectroscopic observation of Rydberg polarons in an atomic Bose gas. Polarons are created by excitation of Rydberg atoms as impurities in a strontium Bose-Einstein conden…
Strong coupling Bose polarons in a BEC
Fabian Grusdt, Richard Schmidt, Yulia E. Shchadilova +1
We use a non-perturbative renormalization group approach to develop a unified picture of the Bose polaron problem, where a mobile impurity is strongly interacting with a surroundin…
Universal many-body response of heavy impurities coupled to a Fermi sea
Richard Schmidt, Michael Knap, Dmitri A. Ivanov +3
In this work we discuss the dynamical response of heavy quantum impurities immersed in a Fermi gas at zero and at finite temperature. Studying both the frequency and the time domai…
Many-body interferometry of magnetic polaron dynamics
Yuto Ashida, Richard Schmidt, Leticia Tarruell +1
The physics of quantum impurities coupled to a many-body environment is among the most important paradigms of condensed matter physics. In particular, the formation of polarons, qu…
