Theory of Superconductivity in the Cuprates (2008)
Aji, Vivek, Shekhter, Arkady, Varma, Chandra
The quantum critical fluctuations of the time-reversal breaking order parameter which is observed in the pseudogap regime of the Cuprates are shown to couple to the lattice equivalent of the local...
Weak Ferromagnetism Accompanying Loop current order in Underdoped Cuprates (2008)
Aji, Vivek, Shekhter, Arkady, Varma, C. M.
We discuss the necessary symmetry conditions and the different ways in which they can be physically realized for the occurrence of ferromagnetism accompanying the loop current orbital magnetic order...
Shekhter, Arkady, Shu, Lei, Aji, Vivek, MacLaughlin, D. E., Varma, C. M.
We calculate the screening charge density distribution due to a point charge, such as that of a positive muon ($\mu^+$), placed between the planes of a highly anisotropic layered metal. In underdoped...
Universality of the single-particle spectra of cuprate superconductors (2007)
Zhu, Lijun, Aji, Vivek, Shekhter, Arkady, Varma, C. M.
All the available data for the dispersion and linewidth of the single-particle spectra above the superconducting gap and the pseudogap in metallic cuprates for any doping has universal features. The...
Branch-cut Singularities in Thermodynamics of Fermi Liquid Systems (2006)
Shekhter, Arkady, Finkel'stein, Alexander M.
The recently measured spin susceptibility of the two dimensional electron gas exhibits a strong dependence on temperature, which is incompatible with the standard Fermi liquid phenomenology. Here we...
