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 Wrześniewski, 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 Wrześniewski, 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. Wrześniewski, 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…
