Interplay between Majorana and Shiba states in a minimal Kitaev chain coupled to a superconductor
Miguel Alvarado, Alfredo Levy Yeyati, Ramón Aguado +1
Two semiconducting quantum dots (QDs) coupled through a superconductor constitute a minimal realisation of a Kitaev chain with Majorana zero modes (MZMs). Such MZMs can be detected…
Non-Hermitian minimal Kitaev chains
Jorge Cayao, Ramón Aguado
Starting from a double quantum dot realization of a minimal Kitaev chain, we demonstrate that non-Hermicity stabilizes the so-called poor man's Majorana zero modes in a region of p…
Thermodynamics of Non-Hermitian Josephson junctions with exceptional points
D. Michel Pino, Yigal Meir, Ramón Aguado
We present an analytical formulation of the thermodynamics, free energy and entropy, of any generic Bogoliubov de Genes model which develops exceptional point (EP) bifurcations in…
Subgap states in semiconductor-superconductor devices for quantum technologies: Andreev qubits and minimal Majorana chains
Rubén Seoane Souto, Ramón Aguado
In recent years, experimental advances have made it possible to achieve an unprecedented degree of control over the properties of subgap bound states in hybrid nanoscale supercondu…
