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…
