Dynamical quantum phase transitions in a hybrid quantum dot system with superconducting and ferromagnetic leads
Antoni Jankiewicz, Kacper Wrześniewski, Ireneusz Weymann
We theoretically explore the non-equilibrium dynamics of a single quantum dot system coupled to both ferromagnetic and superconducting electrodes. To investigate its time evolution…
Effects of correlated hopping on thermoelectric response of a quantum dot strongly coupled to ferromagnetic leads
Kacper WrzeÅniewski, Ireneusz Weymann
We theoretically investigate the impact of correlated hopping on thermoelectric transport through a quantum dot coupled to ferromagnetic leads. Using the accurate numerical renorma…
Entanglement between quantum dots transmitted via Majorana wire: Insights from the fermionic negativity, concurrence and quantum mutual information
C. Jasiukiewicz, A. Sinner, I. Weymann +2
We study quantum entanglement in a system comprising two quantum dots interconnected through the short topological superconducting nanowire, which hosts overlapping boundary Majora…
Double-quantum-dot Andreev molecules: Phase diagrams and critical evaluation of effective models
Peter Zalom, Kacper WrzeÅniewski, Tomáš Novotný +1
This work systematically investigates the phase diagram of a parallel double-quantum-dot Andreev molecule, where the two quantum dots are coupled to a common superconducting lead.…
Spin-dependent signatures of Majorana modes in thermoelectric transport through double quantum dots
Piotr Majek, Ireneusz Weymann
We present a comprehensive theoretical analysis of the spin-dependent thermoelectric properties of a double quantum dot system coupled to a topological superconducting nanowire and…
Transient effects in quantum dots contacted via topological superconductor
R. Taranko, K. WrzeÅniewski, I. Weymann +1
We investigate gradual development of the quasiparticle states in two quantum dots attached to opposite sides of the topological superconducting nanowire, hosting the boundary mode…
