Superconductor–semiconductor hybrid-circuit quantum electrodynamics

G Burkard, MJ Gullans, X Mi, JR Petta - Nature Reviews Physics, 2020 - nature.com
Light–matter interactions at the single-particle level have generally been explored in the
context of atomic, molecular and optical physics. Recent advances motivated by quantum …

Multiterminal josephson effect

N Pankratova, H Lee, R Kuzmin, K Wickramasinghe… - Physical Review X, 2020 - APS
We report a probable observation of the dc Josephson effect in mesoscopic junctions of
three and four superconductors. The devices are fabricated in a top-down fashion from a …

Role of bath-induced many-body interactions in the dissipative phases of the Su-Schrieffer-Heeger model

B Min, K Agarwal, D Segal - Physical Review B, 2024 - APS
The Su-Schrieffer-Heeger chain is a prototype example of a symmetry-protected topological
insulator. Coupling it nonperturbatively to local thermal environments, either through the …

Dissipative topological phase transition with strong system-environment coupling

W Nie, M Antezza, Y Liu, F Nori - Physical Review Letters, 2021 - APS
A primary motivation for studying topological matter regards the protection of topological
order from its environment. In this work, we study a topological emitter array coupled to an …

Hybrid light-matter states in topological superconductors coupled to cavity photons

O Dmytruk, M Schirò - Physical Review B, 2024 - APS
We consider a one-dimensional topological superconductor hosting Majorana bound states
at its ends coupled to a single mode cavity. In the strong light-matter coupling regime …

High-quality poor man's Majorana bound states from cavity embedding

Á Gómez-León, M Schirò, O Dmytruk - arxiv preprint arxiv:2407.12088, 2024 - arxiv.org
Poor man's Majorana Bound States (MBS) arise in minimal Kitaev chains when the
parameters are fine-tuned to a sweet spot. We consider an interacting two-site Kitaev chain …

Parafermions in a multilegged geometry: Towards a scalable parafermionic network

U Khanna, M Goldstein, Y Gefen - Physical Review B, 2022 - APS
Parafermionic zero modes are non-Abelian excitations which have been predicted to
emerge at the boundary of topological phases of matter. Contrary to earlier proposals, here …

Rényi entropy singularities as signatures of topological criticality in coupled photon-fermion systems

FPM Méndez-Córdoba, JJ Mendoza-Arenas… - Physical Review …, 2020 - APS
We show that the topological phase transition for a Kitaev chain embedded in a cavity can
be identified by measuring experimentally accessible photon observables such as the Fano …

Majorana-magnon interactions in topological Shiba chains

PX Shen, V Perrin, M Trif, P Simon - Physical Review Research, 2023 - APS
A chain of magnetic impurities deposited on the surface of a superconductor can form a
topological Shiba band that supports Majorana zero modes and holds a promise for …

Photonic cross-noise spectroscopy of Majorana bound states

L Bittermann, F Dominguez, P Recher - Physical Review B, 2024 - APS
We propose a route to detect Majorana bound states (MBSs) by coupling a topological
superconductor to quantum dots (QDs) in apnp junction. Here two MBSs are coherently …
