Dissipation, topology, and quantum phase transition in a one-dimensional Joesphson junction array
Pallab Goswami, Sudip Chakravarty
We study the phase diagram and quantum critical properties of a resistively shunted Josephson junction array in one dimension from a strong coupling analysis. After mapping the dis…
Resonating plaquette phase of a quantum six-vertex model
Olav F. Syljuasen, Sudip Chakravarty
The simplest quantum generalization of the six-vertex model describes fluctuations of the order parameter of the d-density wave (DDW), believed to compete with superconductivity in…
Criticality in correlated quantum matter
Angela Kopp, Sudip Chakravarty
At quantum critical points (QCP) \cite{Pfeuty:1971,Young:1975,Hertz:1976,Chakravarty:1989,Millis:1993,Chubukov:1 994,Coleman:2005} there are quantum fluctuations on all length scal…
Modulation of the local density of states within the -density wave theory in the underdoped cuprates
Amit Ghosal, Angela Kopp, Sudip Chakravarty
The low temperature scanning tunneling microscopy spectra in the underdoped regime is analyzed from the perspective of coexisting -density wave and d-wave superconducting states…
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…
Fourier Transformed Scanning Tunneling Peaks in the -density wave phase
Cristina Bena, Sudip Chakravarty, Jiangping Hu +1
In this brief note we repeat an earlier calculation of the Fourier transformed scanning tunneling spectra of the -density wave (DDW) phase using a different band structure, whic…
