Phase diagram of the disordered Kitaev chain with long range pairing connected to external baths
Emmanuele G. Cinnirella, Andrea Nava, Gabriele Campagnano +1
We study the phase diagram of a disordered Kitaev chain with long-range pairing when connected to two metallic leads exchanging particles with external Lindblad baths. We (i) monit…
The fate of high winding number topological phases in the disordered extended Su-Schrieffer-Heeger model
Emmanuele G. Cinnirella, Andrea Nava, Gabriele Campagnano +1
We use the Lindblad equation approach to investigate topological phases hosting more than one localized state at each side of a disordered SSH chain with properly tuned long range…
Lindblad master equation approach to the topological phase transition in the disordered Su-Schrieffer-Heeger model
Andrea Nava, Gabriele Campagnano, Pasquale Sodano +1
We use the Lindblad equation method to investigate the onset of a mobility edge and the topological phase transition in the disordered SSH chain connected to two external baths in…
Persistent current and zero-energy Majorana modes in a p-wave disordered superconducting ring
Andrea Nava, Rosa Giuliano, Gabriele Campagnano +1
We discuss the emergence of zero-energy Majorana modes in a disordered finite-length p-wave one-dimensional superconducting ring, pierced by a magnetic flux tuned at an appropr…
Junction of three off-critical quantum Ising chains and two-channel Kondo effect in a superconductor
Domenico Giuliano, Gabriele Campagnano, Arturo Tagliacozzo
We show that a junction of three off-critical quantum Ising chains can be regarded as a quantum spin chain realization of the two-channel spin-1/2 overscreened Kondo effect with tw…
Transfer matrix approach to the persistent current in hybrid normal-superconducting rings
Andrea Nava, Rosa Giuliano, Gabriele Campagnano +1
Using the properties of the transfer matrix of one-dimensional quantum mechanical systems, we derive a technique to exactly compute the persistent current across a hybrid normal-su…
Josephson versus Kondo coupling in a quantum dot connected to two superconductors
Gabriele Campagnano, Domenico Giuliano, Adele Naddeo +1
We apply a Gutzwiller-like variational technique to study Josephson conduction across a quantum dot with an odd number of electrons connected to two superconducting leads. Our meth…
Josephson Current in a Quantum Dot in the Kondo Regime Connected to Two Superconductors
G. Campagnano, D. Giuliano, A. Tagliacozzo
We apply a Gutzwiller-like variational technique to study Josephson conduction across a quantum dot with an odd number of electrons connected to two superconducting leads. We show…
