Violation of the Wiedemann-Franz law in the Topological Kondo model
Francesco Buccheri, Andrea Nava, Reinhold Egger +2
We study the thermal transport through a Majorana island connected to multiple external quantum wires. In the presence of a large charging energy, we find that the Wiedemann-Franz…
Multi-particle scattering and breakdown of the Wiedemann-Franz law at a junction of N interacting quantum wires
D. Giuliano, A. Nava, R. Egger +2
We analyze the charge and thermal transport at a junction of interacting quantum wires close to equilibrium. Within the framework of Tomonaga-Luttinger liquids, we compute the ther…
Kondo Length in Bosonic Lattices
Domenico Giuliano, Pasquale Sodano, Andrea Trombettoni
Motivated by the fact that the low-energy properties of the Kondo model can be effectively simulated in spin chains, we study the realization of the effect with bond impurities in…
Josephson effect in Majorana box devices
A. Zazunov, F. Buccheri, P. Sodano +1
We study Majorana devices featuring a competition between superconductivity and multi-channel Kondo physics. Our proposal extends previous work on single-channel Kondo systems to a…
Unveiling Majorana Quasiparticles by a Quantum Phase Transition: Proposal of a Current Switch
F. A. Dessotti, L. S. Ricco, Y. Marques +6
We propose a theoretical approach based on an interferometer composed by two quantum dots asymmetrically coupled to isolated Majorana quasiparticles (MQPs), lying on the edges of t…
Majorana Entanglement Bridge
S. Plugge, A. Zazunov, P. Sodano +1
We study the concurrence of entanglement between two quantum dots in contact to Majorana bound states on a floating superconducting island. The distance between the Majorana states…
Two-impurity helical Majorana problem
E. Eriksson, A. Zazunov, P. Sodano +1
We predict experimentally accessible signatures for helical Majorana fermions in a topological superconductor by coupling to two quantum dots in the local moment regime (correspond…
Even-odd parity effects in Majorana junctions
A. Zazunov, P. Sodano, R. Egger
We study a general Majorana junction, where N helical nanowires are connected to a common s-wave superconductor proximity-inducing Majorana bound states in the wires. The normal pa…
Nonlocal Handbury-Brown Twiss Interferometry & Entanglement Generation from Majorana Bound States
Sougato Bose, Pasquale Sodano
We show that a one dimensional device supporting a pair of Majorana bound states at its ends can produce remarkable Hanbury-Brown Twiss like interference effects between well separ…
Frustration of decoherence in -shaped superconducting Josephson networks
D. Giuliano, P. Sodano
We examine the possibility that pertinent impurities in a condensed matter system may help in designing quantum devices with enhanced coherent behaviors. For this purpose, we analy…
Boundary Field Theory Approach to the Renormalization of SQUID Devices
Domenico Giuliano, Pasquale Sodano
We show that the quantum properties of some Josephson SQUID devices are described by a boundary sine Gordon model. Our approach naturally describes multi-junction SQUID devices and…
