Nonadiabatic landau–zener–stückelberg–majorana transitions, dynamics, and interference

V Ivakhnenko, SN Shevchenko, F Nori - Physics Reports, 2023 - Elsevier
Since the pioneering works by Landau, Zener, Stückelberg, and Majorana (LZSM), it has
been known that driving a quantum two-level system results in tunneling between its states …

Quantum metric induced phases in moiré materials

A Abouelkomsan, K Yang, EJ Bergholtz - Physical Review Research, 2023 - APS
We show that, quite generally, quantum geometry plays a major role in determining the low-
energy physics in strongly correlated lattice models at fractional band fillings. We identify …

The dynamical properties of multiterminal Josephson junctions (MT-JJs) have attracted
interest, driven by the promise of new insights into synthetic topological phases of matter …

Quantum interferometer for quartets in superconducting three-terminal Josephson junctions

R Mélin, D Feinberg - Physical Review B, 2023 - APS
An interferometric device is proposed in order to analyze the quartet mode in biased three-
terminal Josephson junctions (TTJs), and to provide experimental evidence for the …

Proposal for detecting the -shifted Cooper quartet supercurrent

R Mélin, R Danneau, CB Winkelmann - Physical Review Research, 2023 - APS
The multiterminal Josephson effect aroused considerable interest recently, in connection
with theoretical and experimental evidence for correlations among Cooper pairs, that is, the …

Quartet tomography in multiterminal Josephson junctions

DC Ohnmacht, M Coraiola, JJ García-Esteban… - Physical Review B, 2024 - APS
We investigate the detection of quartets in hybrid multiterminal Josephson junctions. Using
simple models of quantum dots coupled to superconducting leads, we find that quartets are …

Driven Andreev molecule

A Keliri, B Douçot - Physical Review B, 2023 - APS
We study the voltage-biased S-QD-S-QD-S Josephson junction, composed of three
superconductors (S) and two quantum dots (QDs). In the absence of an applied voltage, the …

Non-Abelian monopoles in the multiterminal Josephson effect

HY Xie, J Hasan, A Levchenko - Physical Review B, 2022 - APS
In this Letter we present a detailed theoretical analysis for the spectral properties of Andreev
bound states in the multiterminal Josephson junctions by employing a symmetry-constrained …

Long-range coupling between superconducting quantum dots induced by periodic driving

A Keliri, B Douçot - Physical Review B, 2023 - APS
We consider a Josephson bijunction consisting of three superconducting reservoirs
connected through two quantum dots. In equilibrium, the interdot coupling is sizable only for …
