Chiral-helical junctions in screened graphene
Bilal Kousar, Selma Franca, David Perconte +14
Reproducibility and quantization in quantum spin Hall platforms is a persisting challenge, limiting their use in hybrid realizations of topological superconductivity. We report rob…
Dissipation due to Bulk Localized Low-Energy Modes in Strongly Disordered Superconductors
Anton V. Khvalyuk, Mikhail V. Feigel'man
Strongly disordered superconductors (SDSCs) are widely used in qubits, microwave resonators, photon detectors, and other superconducting quantum devices. In SDSC-based devices, coh…
Universal bound on microwave dissipation in superconducting circuits
Thibault Charpentier, Anton Khvalyuk, Lev Ioffe +3
Improving the coherence of superconducting qubits is essential for advancing quantum technologies. While superconductors are theoretically perfect conductors, they consistently exh…
First-order quantum breakdown of superconductivity in amorphous superconductors
Thibault Charpentier, David Perconte, Sébastien Léger +10
Continuous quantum phase transitions are widely assumed and frequently observed in various systems of quantum particles or spins. Their characteristic trait involves scaling laws g…
Influence of Trotterization error on single-particle tunneling
Anton V. Khvalyuk, Kostyantyn Kechedzhi, Vadim S. Smelyansky +1
Existing superconducting quantum devices struggle to simulate spatial quantum tunneling as it is exponentially slow and inherently nonlocal. The Suzuki-Trotter algorithm (STA) offe…
Near-power-law temperature dependence of the superfluid stiffness in strongly disordered superconductors
Anton V. Khvalyuk, Thibault Charpentier, Nicolas Roch +2
In BCS superconductors, the superfluid stiffness is virtually constant at low temperature and only slightly affected by the exponentially low density of thermal quasiparticles. Her…
Distribution of the order parameter in strongly disordered superconductors: An analytic theory
Anton V. Khvalyuk, Mikhail V. Feigel'man
We developed an analytic theory of inhomogeneous superconducting pairing in strongly disordered materials, which are moderately close to superconducting-insulator transition. Singl…
