Negative differential conductance in triangular molecular assemblies
Chao Li, Vladislav Pokorný, Prokop Hapala +7
We report the creation and characterization of a molecular-scale negative differential conductance (NDC) device by assembling a triangular trimer of 4,5,9,10-tetrabromo-1,3,6,8-tet…
Hidden symmetry in interacting-quantum-dot-based multi-terminal Josephson junctions
Peter Zalom, Martin Žonda, T. Novotný
We study a multi-terminal Josephson junction based on an interacting quantum dot coupled to superconducting BCS leads. Using an Anderson type model of a local level with an arb…
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…
Unified theory of quantum phase transitions in quantum dots with gapped host bands
Peter Zalom, Martin Žonda
We present a unified theory of quantum phase transitions for half-filled quantum dots (QDs) coupled to gapped host bands. We augment the bands by additional weakly coupled metallic…
Second Order Perturbation Theory for a Superconducting Double Quantum Dot
Vladislav Pokorný, Martin Žonda, Georgios Loukeris +1
We extend our approach based on the second order perturbation theory in the Coulomb interaction recently developed for quantum dots coupled to superconducting leads to the supercon…
