Topological Kondo effect with spinful Majorana fermions

S Bollmann, JI Väyrynen, EJ König - Physical Review B, 2024 - APS
Motivated by the importance of studying topological superconductors beyond the mean-field
approximation, we here investigate mesoscopic islands of time-reversal-invariant …

Extended Ginzburg-Landau theory of superconductivity from generalized momentum operator and position-dependent mass

RA El-Nabulsi, W Anukool - Physica B: Condensed Matter, 2024 - Elsevier
The concept of generalized momentum operator which is motivated from the generalized

Phase-coherent dynamics of quantum devices with local interactions

M Filippone, A Marguerite, K Le Hur, G Fève, C Mora - Entropy, 2020 - mdpi.com
This review illustrates how Local Fermi Liquid (LFL) theories describe the strongly correlated
and coherent low-energy dynamics of quantum dot devices. This approach consists in an …

Topological symplectic Kondo effect

G Li, EJ König, JI Väyrynen - Physical Review B, 2023 - APS
Multiple conduction channels interacting with a quantum impurity—a spin in the
conventional “multichannel Kondo effect” or a topological mesoscopic device (“topological …

Topological Quantum Impurity Models

G Li - 2024 - hammer.purdue.edu
A bath of free electrons interacting with a local quantum impurity leads to various exotic non-
Fermi liquid behaviors, such as the non-integer effective ground state degeneracy of the …

Memory-critical dynamical buildup of phonon-dressed Majorana fermions

O Kaestle, Y Sun, Y Hu, A Carmele - Physical Review B, 2020 - APS
We investigate the dynamical interplay between the topological state of matter and a non-
Markovian dissipation, which gives rise to a crucial timescale into the system dynamics due …
