d-Wave superconductivity on the checkerboard Hubbard model at weak and strong coupling
Shiladitya Chakraborty, David Sénéchal, A. -M. S. Tremblay
It has been argued that inhomogeneity generally can enhance superconductivity in the cuprate high-Tc materials. To check the validity of this claim, we study d-wave superconductivi…
Non-conservation of Fermionic Degrees of Freedom at Low-energy in Doped Mott Insulators
Shiladitya Chakraborty, Seungmin Hong, Philip Phillips
Hall and optical conductivity experiments on the cuprates indicate that the low-energy fermionic degrees of freedom in a doped Mott insulator posess a component that is dynamcially…
Charge 2e Boson Underlies Two - Fluid Model of the Pseudogap in Cuprate Superconductors
Shiladitya Chakraborty, Philip Phillips
Starting from the effective low energy theory of a doped Mott insulator, we show that the effective carrier density in the underdoped regime agrees with a two - fluid description.…
Emergence of Particle-Hole Symmetry near Optimal Doping in High-Temperature Copper Oxide Superconductors
Shiladitya Chakraborty, Dimitrios Galanakis, Philip Phillips
High-temperature copper oxide superconductors (cuprates) display unconventional physics when they are lightly doped whereas the standard theory of metals prevails in the opposite r…
Kinks and Mid-Infrared Optical Conductivity from Strong Electron Correlation
Shiladitya Chakraborty, Dimitrios Galanakis, Philip Phillips
We compute the one-particle spectral function and the optical conductivity for the 2-d Hubbard model on a square lattice. The computational method is cellular dynamical mean-field…
