Theory of three-terminal Andreev spin qubits
Kiryl Piasotski, Aleksandr Svetogorov, Wolfgang Belzig +1
In this paper, we introduce a concise theoretical framework for the equilibrium three-terminal Josephson effect in spin-orbit-interacting systems, inspired by recent experiments on…
Experimental realization of qubit-state-controlled directional edge states in waveguide QED
Prasanna Pakkiam, N. Pradeep Kumar, Chun-Ching Chiu +3
We experimentally realise the theoretical proposal for in-situ tunable photonic edge states emerging from qubits coupled to a waveguide with a photonic bandgap. These edge states a…
Green's functions of quasi-one-dimensional layered systems and their application to Josephson junctions
Kiryl Piasotski, Mikhail Pletyukhov, Alexander Shnirman
We develop Green's function formalism to describe continuous multi-layered quasi-one-dimensional setups described by piece-wise constant single-particle Hamiltonians. The Hamiltoni…
Realization of a three-dimensional quantum Hall effect in a Zeeman-induced second order topological insulator on a torus
Zhe Hou, Clara S. Weber, Dante M. Kennes +4
We propose a realization of a quantum Hall effect (QHE) in a second-order topological insulator (SOTI) in three dimensions (3D), which is mediated by hinge states on a torus surfac…
Second-order topology and supersymmetry in two-dimensional topological insulators
Clara S. Weber, Mikhail Pletyukhov, Zhe Hou +4
We unravel a fundamental connection between supersymmetry and a wide class of two dimensional second-order topological insulators (SOTI). This particular supersymmetry is induced b…
Qubit-controlled directional edge states in waveguide QED
Prasanna Pakkiam, N. Pradeep Kumar, Mikhail Pletyukhov +1
We propose an in-situ tunable chiral quantum system, composed of a quantum emitter coupled to a waveguide based on the Rice-Mele model (where we alternate both the on-site potentia…
