Violation of the Wiedemann-Franz law in the topological Kondo model

F Buccheri, A Nava, R Egger, P Sodano, D Giuliano - Physical Review B, 2022 - APS
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 …

[HTML][HTML] Anomalous universal conductance as a hallmark of non-locality in a Majorana-hosted superconducting island

Y Hao, G Zhang, D Liu, DE Liu - Nature Communications, 2022 - nature.com
The non-local feature of topological states of matter is the key for the topological protection
of quantum information and enables robust non-local manipulation in quantum information …

Delta- noise for weak tunneling in one-dimensional systems: Interactions versus quantum statistics

G Zhang, IV Gornyi, C Spånslätt - Physical Review B, 2022 - APS
We study delta-T noise—excess charge noise at zero voltage but finite temperature bias—
for weak tunneling in one-dimensional interacting systems. We show that the sign of the …

Multiparticle scattering and breakdown of the Wiedemann-Franz law at a junction of interacting quantum wires

D Giuliano, A Nava, R Egger, P Sodano, F Buccheri - Physical Review B, 2022 - APS
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 …

Topological Kondo device for distinguishing quasi-Majorana and Majorana signatures

D Liu, Z Cao, X Liu, H Zhang, DE Liu - Physical Review B, 2021 - APS
To confirm the Majorana signatures, significant effort has been devoted to distinguishing
between Majorana zero modes (MZMs) and spatially separated quasi-Majorana modes …

Topological Kondo model out of equilibrium

MM Wauters, CM Chung, L Maffi, M Burrello - Physical Review B, 2023 - APS
