Floating phase in a dissipative Josephson junction array
Sumanta Tewari, John Toner, Sudip Chakravarty
We consider dissipative quantum phase transitions in Josephson junction arrays and show that the disordered phase in this extended system can be viewed as an unusual floating phase…

Softer than normal, but not as soft as one might think: Spontaneous flux lattices in ferromagnetic spin-triplet superconductors
Sumanta Tewari, D. Belitz, T. R. Kirkpatrick +1
A theory is developed for the spontaneous vortex lattice that is expected to occur in the ferromagnetic superconductors ZrZn_2, UGe_2, and URhGe, where the superconductivity is lik…
