Statistical Signatures of Majorana Zero Modes in Disordered Topological Superconductor Antidot Vortices
Zhibo Ren, Jukka I. Väyrynen
An antidot-pinned vortex in a three-dimensional topological insulator-superconductor platform hosts a Majorana zero mode (MZM). However, numerous Caroli-de Gennes-Matricon (CdGM) s…
Many-Body Entanglement Properties of Finite Interacting Fermionic Hamiltonians
Irakli Giorgadze, Grayson Welch, Haixuan Huang +2
We analyze many-body entanglement in interacting fermionic systems by using the -body reduced density matrix. We demonstrate that if a particle number conserving fermionic Hamil…
Wiedemann-Franz violation and thermal Hall effect in kagome metal TbCr6Ge6
Jhinkyu Choi, Mohan B. Neupane, L. H. Vilela-Leão +5
The thermal Hall effect has emerged as a powerful probe of exotic excitations in correlated quantum materials, providing access to charge-neutral heat carriers that remain invisibl…
High efficiency superconducting diode effect in a gate-tunable double-loop SQUID
Wyatt Gibbons, Teng Zhang, Kevin Barrow +3
In superconducting quantum interference devices (SQUIDs), the superconducting diode effect may be generated by interference of multiple harmonic components in the current-phase rel…
Native-oxide-passivated trilayer junctions for superconducting qubits
Pankaj Sethi, Om Prakash, Jukka-Pekka Kaikkonen +15
Superconducting qubits in today's quantum processing units are typically fabricated with angle-evaporated aluminum--aluminum-oxide--aluminum Josephson junctions. However, there is…
Unveiling In-Gap States and Majorana Zero Modes in Superconductor-Topological Insulator Bilayer model
Umesh Kumar, Rafal Rechcinski, Tatiana de Picoli +2
Interfaces between topological insulators and superconductors are promising platforms for realizing Majorana zero modes (MZMs) via the superconducting proximity effect. We introduc…
