Non-identical anyonic algebras from compact-field quantum geometry
O. Kashuba, R. Mummadavarapu, R. -P. Riwar
Compact scalar field theories on lattices are capable of describing a large class of many-body systems, such as interacting bosons, superconducting circuit networks, spin systems a…

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…

Limitations of Caldeira-Leggett model for description of phase transitions in superconducting circuits
O. Kashuba, R. -P. Riwar
The inherent complexity of system-bath interactions often requires making critical approximations, which we here show to have a radical influence on the renormalization group flow…
