Cooper pair charge Kondo effect in a hybrid quantum dot - superconductor device
Luca Gonfiantini, Lorenzo Maffi, Michele Burrello
We consider a tunable hybrid device composed of four quantum dots and a floating superconducting island -- the so-called poor man's tetron -- close to its effective particle-hole s…
The topological Kondo model out of equilibrium
Matteo M. Wauters, Chia-Min Chung, Lorenzo Maffi +1
The topological Kondo effect is a genuine manifestation of the nonlocality of Majorana modes. We investigate its out-of-equilibrium signatures in a model with a Cooper-pair box hos…
Simulations of the dynamics of quantum impurity problems with matrix product states
Matteo M. Wauters, Chia-Min Chung, Lorenzo Maffi +1
The Anderson impurity model is a paradigmatic example in the study of strongly correlated quantum systems and describes an interacting quantum dot coupled to electronic leads. In t…
Strange correlators for topological quantum systems from bulk-boundary correspondence
Luca Lepori, Michele Burrello, Andrea Trombettoni +1
"Strange" correlators provide a tool to detect topological phases arising in many-body models by computing the matrix elements of suitably defined two-point correlations between th…
Dyonic zero-energy modes
Morten I. K. Munk, Asbjørn Rasmussen, Michele Burrello
One-dimensional systems with topological order are intimately related to the appearance of zero-energy modes localized on their boundaries. The most common example is the Kitaev ch…
Axial anomaly in multi-Weyl and triple-point semimetals
Luca Lepori, Michele Burrello, Enore Guadagnini
We derive the expression of the abelian axial anomaly in the so-called multi-Weyl and triple-point crossing semimetals. No simplifying restrictions are assumed on the symmetry of t…
