Tuning the inductance of Josephson junction arrays without SQUIDs
Roman Kuzmin, Nitish Mehta, Nicholas Grabon +1
It is customary to use arrays of superconducting quantum interference devices (SQUIDs) for implementing magnetic field-tunable inductors. Here, we demonstrate an equivalent tunabil…
Inelastic scattering of a photon by a quantum phase-slip
Roman Kuzmin, Nicholas Grabon, Nitish Mehta +5
Spontaneous decay of a single photon is a notoriously inefficient process in nature irrespective of the frequency range. We report that a quantum phase-slip fluctuation in high-imp…
Superstrong coupling in circuit quantum electrodynamics
Roman Kuzmin, Nitish Mehta, Nicholas Grabon +2
Vacuum fluctuations fundamentally affect an atom by inducing a finite excited state lifetime along with a Lamb shift of its transition frequency. Here we report the reverse effect:…
Quantum electrodynamics of a superconductor-insulator phase transition
Roman Kuzmin, Raymond Mencia, Nicholas Grabon +3
A chain of Josephson junctions implements one of the simplest many-body models undergoing a superconductor-insulator (SI) quantum phase transition between states with zero and infi…
