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…
Interaction Effects in the Mesoscopic Regime: A Quantum Monte Carlo Study of Irregular Quantum Dots
Amit Ghosal, C. J. Umrigar, Hong Jiang +2
We address the issue of accurately treating interaction effects in the mesoscopic regime by investigating the ground state properties of isolated irregular quantum dots. Quantum Mo…
Antiferromagnetism and charged vortices in high-Tc superconductors
Daniel Knapp, Catherine Kallin, Amit Ghosal +1
The effect of the long-range Coulomb interaction on charge accumulation in antiferromagnetic vortices in high-Tc superconductors is studied within a Bogoliubov-de Gennes mean-field…
Spatial Inhomogeneities in Disordered d-Wave Superconductors: Effect on Density of States and Superfluid Stiffness
Amit Ghosal, Mohit Randeria, Nandini Trivedi
We study a short coherence length d-wave superconductor with finite density of unitary scatterers using the Bogoliubov-deGennes technique. We find that the low-energy density of st…
