Crossover and scaling in a two-dimensional field-tuned superconductor
Sumanta Tewari
Using an analysis similar to that of Imry and Wortis, it is shown that the apparent first order superconductor to metal transition, which has been claimed to exist at low values of…

Collective modes in the d-density wave state of the cuprates
Sumanta Tewari, Sudip Chakravarty
Using a functional integral formulation, we analyze the collective modes in the -density wave state. Since only discrete symmetries are broken, no massless phase mode is present…

Sharp signature of DDW quantum critical point in the Hall coefficient of the cuprates
Sudip Chakravarty, Chetan Nayak, Sumanta Tewari +1
We study the behavior of the Hall coefficient, , in a system exhibiting density-wave (DDW) order in a regime in which the carrier concentration, , is tune…
