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…
Comment on "Memory Effects in an Interacting Magnetic Nanoparticle System" by Sun et. al, prl, 91, 167206 (2003)
S. Chakravarty, A. Frydman, M. Bandyopadhyay +2
In this Comment we report a phenomenon identical to that observed in ({Y. Sun, M. B. Salamon, K. Garnier and R. S. Averback, Phys. Rev. Lett. 91, 167206 (2003)}) for systems of NiF…
Phase diagram and critical exponents of a dissipative Ising spin chain in a transverse magnetic field
Philipp Werner, Klaus Voelker, Matthias Troyer +1
We consider a one-dimensional Ising model in a transverse magnetic field coupled to a dissipative heat bath. The phase diagram and the critical exponents are determined from extens…
