Certified reduced-basis emulation of conformal field theories on the fuzzy sphere
Virgil V. Baran
Fuzzy-sphere regularization gives numerical access to three-dimensional conformal field theories (CFTs), but locating one requires testing for criticality across the parameter spac…
Reduced Basis Method for Driven-Dissipative Quantum Systems
Hans Christiansen, Virgil V. Baran, Jens Paaske
Reduced basis methods provide an efficient way of mapping out phase diagrams of strongly correlated many-body quantum systems. The method relies on using the exact solutions at sel…
Yu-Shiba-Rusinov states in color superconducting quark matter
Virgil V. Baran, Jens Paaske
The high-density region of the QCD phase diagram displays an intricate competition between color superconductivity and the QCD Kondo effect due to color exchange in quark matter co…
The poor man's Majorana tetron
Maximilian Nitsch, Lorenzo Maffi, Virgil V. Baran +4
The Majorana tetron is a prototypical topological qubit stemming from the ground state degeneracy of a superconducting island hosting four Majorana modes. This degeneracy manifests…
Majorana modes in quantum dots coupled via a floating superconducting island
R. Seoane Souto, V. V. Baran, M. Nitsch +4
Majorana modes can be engineered in arrays where quantum dots (QDs) are coupled via grounded superconductors, effectively realizing an artificial Kitaev chain. Minimal Kitaev chain…
Spin-1 Haldane chains of superconductor-semiconductor hybrids
Virgil V. Baran, Jens Paaske
We theoretically explore the possibility of realizing the symmetry-protected topological Haldane phase of spin-1 chains in a tunable hybrid platform of superconducting islands (SIs…
BCS surrogate models for floating superconductor-semiconductor hybrids
Virgil V. Baran, Jens Paaske
Superconductor-semiconductor hybrid devices, involving quantum dots interfaced with floating and/or grounded superconductors, have reached a level of complexity which calls for the…
