Correlated States in Quantum Dot Clusters Coupled to a Common Superconductor
Martin Žonda, Jakub Rękas, Tobiáš Poláček +3
We study an effective model of regular quantum dot clusters coupled to a common superconductor. By applying a canonical transformation, we map the system onto a particle-number-con…
Failure of the Baym-Kadanoff construction to match consistently quantum dynamics with thermodynamic critical behavior
Václav Janiš, Vladislav Pokorný, Šimon Kos
We disclose a serious deficiency of the Baym-Kadanoff construction of thermodynamically consistent conserving approximations. There are two vertices in this scheme: dynamical and c…
Generalized atomic limit of a double quantum dot coupled to superconducting leads
Martin Žonda, Peter Zalom, Tomáš Novotný +3
We present an exactly solvable effective model of a double quantum dot coupled to superconducting leads. This model is a generalization of the well-known superconducting atomic lim…
Effective low-energy models for superconducting impurity systems
Vladislav Pokorný, Martin Žonda
We present two complementary methods to calculate the Andreev bound state energies of a single-level quantum dot connected to superconducting leads described by the superconducting…
Evolution of the Andreev bands in the half-filled superconducting periodic Anderson model
Vladislav Pokorný, Panch Ram
We employ the periodic Anderson model with superconducting correlations in the conduction band at half filling to study the behavior of the in-gap bands in a heterostructure consis…
Footprints of impurity quantum phase transitions in quantum Monte Carlo statistics
Vladislav Pokorný, Tomáš Novotný
Interacting single-level quantum dot connected to BCS superconducting leads represents a well-controllable system to study the interplay between the correlation effects and the ele…
