Strongly nonlinear regime of Josephson transmission lines revealed by two-tone spectroscopy
A. S. Averkin, A. A. Kopasov, I. E. Pologov +5
We present experimental and theoretical studies of the off-resonant and strongly nonlinear regime of Josephson transmission lines (JTLs) with galvanically-coupled nonlinear element…
Collective quantum phases in frustrated arrays of Josephson junctions
M. V. Fistul, O. Neyenhuys, B. Pernack +3
We study collective quantum phases and quantum phase transitions occurring in frustrated sawtooth arrays of small quantum Josephson junctions. Frustration is introduced through the…
Quantum dynamics of frustrated Josephson junction arrays embedded in a transmission line: an effective XX spin chain with long-range interaction
Benedikt J. P. Pernack, Mikhail V. Fistul, Ilya M. Eremin
We study theoretically a variety of collective quantum phases occurring in frustrated saw-tooth chains of Josephson junctions embedded in a dissipationless transmission line. The b…
Schrieffer-Wolff transformation for non-Hermitian systems: application for -symmetric circuit QED
Grigory A. Starkov, Mikhail V. Fistul, Ilya M. Eremin
Combining non-hermiticity and interactions yields novel effects in open quantum many-body systems. Here, we develop the generalized Schrieffer-Wolff transformation and derive the e…
Long-range Ising spins models emerging from frustrated Josephson junctions arrays with topological constraints
Oliver Neyenhuys, Mikhail V. Fistul, Ilya M. Eremin
Geometrical frustration in correlated systems can give rise to a plethora of novel ordered states and intriguing phases. Here, we analyze theoretically vertex-sharing frustrated Ka…
Formation of Exceptional Points in pseudo-Hermitian Systems
Grigory A. Starkov, Mikhail V. Fistul, Ilya M. Eremin
Motivated by the recent growing interest in the field of -symmetric Hamiltonian systems we theoretically study the emergency of singularities called Excepti…
