The structure of quasiparticles in a local Fermi liquid
I. Snyman
Conduction electrons interacting with a dynamic impurity can give rise to a local Fermi liquid. The latter has the same low energy spectrum as an ideal Fermi gas containing a stati…
Comment on "Absence versus Presence of Dissipative Quantum Phase Transition in Josephson Junctions''
Théo Sépulcre, Serge Florens, Izak Snyman
In a recent Letter [Phys. Rev. Lett. 129, 087001, (2022)], Masuki, Sudo, Oshikawa, and Ashida studied a Josephson junction, with Josephson energy and charging energy $E…
Revealing the finite-frequency response of a bosonic quantum impurity
Sébastien Léger, Théo Sépulcre, Dorian Fraudet +7
Quantum impurities are ubiquitous in condensed matter physics and constitute the most stripped-down realization of many-body problems. While measuring their finite-frequency respon…
Simulating realistic screening clouds around quantum impurities: role of spatial anisotropy and disorder
Maxime Debertolis, Izak Snyman, Serge Florens
Dynamical quantum impurities in metals induce electronic correlations in real space that are difficult to simulate due to their multi-scale nature, so that only s-wave scattering i…
Efficient impurity-bath trial states from superposed Slater determinants
Izak Snyman, Serge Florens
The representation of ground states of fermionic quantum impurity problems as superpositions of Gaussian states has recently been given a rigorous mathematical foundation. [S. Brav…
Few-body nature of Kondo correlated ground states
Maxime Debertolis, Serge Florens, Izak Snyman
The quenching of degenerate impurity states in metals generally induces a long-range correlated quantum state known as the Kondo screening cloud. While a macroscopic number of part…
