Flux noise without flux tunability in superconducting qubits
Daniel Kruti, Roman-Pascal Riwar
Flux noise is unanimously recognised as a leading dephasing mechanism for flux-tunable superconducting qubits. However, our microscopic understanding remains incomplete, and basic…
Interplay between evanescent scattering modes and finite dispersion in superconducting junctions
Daniel Kruti, Roman-Pascal Riwar
Superconducting junctions are essential building blocks for quantum hardware, and their fundamental behaviour remains a highly active research field. The behaviour of generic junct…
On-demand analog space-time in superconducting networks: grey holes, dynamical instability and exceptional points
Mohammad Atif Javed, Daniel Kruti, Ahmed Kenawy +4
There has been considerable effort to mimic analog black holes and wormholes in solid state systems. Lattice realizations in particular present specific challenges. One of those is…
Fractionalized quantum criticality in spin-orbital liquids from field theory beyond the leading order
Shouryya Ray, Bernhard Ihrig, Daniel Kruti +3
Two-dimensional spin-orbital magnets with strong exchange frustration have recently been predicted to facilitate the realization of a quantum critical point in the Gross-Neveu-SO(3…
