Spectral properties of fractionalized Shiba states
Cătălin Paşcu Moca, Csanád Hajdú, Balázs Dóra +1
A magnetic impurity in a BCS superconductor induces the formation of a Shiba state and drives a local quantum phase transition. We generalize this concept to a one-dimensional supe…
Momentum space magic for the transverse field quantum Ising model
Balázs Dóra, Cătălin Paşcu Moca
Stabilizer entropies and quantum magic have been extensively explored in real-space formulations of quantum systems within the framework of resource theory. However, interesting an…
Kondo Compensation in a Pseudogap Phase: a Renormalization Group Study
Csanád Hajdú, Cătălin Paşcu Moca, Balázs Dóra +2
We investigate the critical behavior of the Kondo compensation in the presence of a power-law pseudogap in the density of states, . For , this model exhi…
Non-equilibrium dynamics of superconductivity in the Hatsugai-Kohmoto model
Ádám Bácsi, Balázs Dóra
We study the non-equilibrium dynamics of the superconducting order parameter in the Hatsugai-Kohmoto (HK) model. In the absence of superconductivity, its ground state is a non-Ferm…
