Supercurrent as a bulk probe for topological phase
Tatiana de Picoli, Ian Wojtowicz, Jukka I. Vayrynen
Distinguishing trivial from topological superconducting phase remains a central and contested experimental challenge, since most existing probes infer the bulk phase transition ind…
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…
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…
Appearance of Multiple Spectral Gaps in Voltage-Biased Josephson Junctions Without Floquet Hybridization
Teng Zhang, Tatiana de Picoli, Tyler Lindemann +2
A time-periodic drive enables the engineering of non-equilibrium quantum systems by hybridizing Floquet sidebands. We investigated DC voltage-biased planar Josephson junctions buil…
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…
Design and benchmarks for emulating Kondo dynamics on a quantum chip
Soumyadeep Sarma, Jukka I. Väyrynen, Elio J. König
Motivated by recent advances in digital quantum simulation and the overall prospective of solving correlated many-electron problems using quantum algorithms, we design a gate-based…
Superconducting Diode Effect in Two-dimensional Topological Insulator Edges and Josephson Junctions
Haixuan Huang, Tatiana de Picoli, Jukka I. Väyrynen
The superconducting diode effect -- the dependence of critical current on its direction -- can arise from the simultaneous breaking of inversion and time-reversal symmetry in a sup…
A Platform for Braiding Majorana Modes with Magnetic Skyrmions
Shiva T. Konakanchi, Jukka I. Väyrynen, Yong P. Chen +2
After a decade of intense theoretical and experimental efforts, demonstrating braiding of Majorana modes remains an unsolved problem in condensed matter physics due to platform spe…
Edge spin transport in the disordered two-dimensional topological insulator WTe
Justin Copenhaver, Jukka I. Väyrynen
The spin conductance of two-dimensional topological insulators (2D TIs) is not expected to be quantized in the presence of perturbations that break the spin-rotational symmetry. Ho…

Deividas Sabonis, David van Zanten, Judith Suter +7
Transport studies of Andreev bound states (ABSs) are complicated by the interplay of charging effects and superconductivity. Here, we compare transport approaches to ABS spectrosco…
