Superfluid Density in Conventional Superconductors: From Clean to Strongly Disordered
Surajit Dutta, Pratap Raychaudhuri, Sudhansu S. Mandal +1
The highly convergent form of superfluid density in disordered conventional superconductors available in the literature and independently obtained by us following the approach of a…
Microscopic free energy functional of superconductive amplitude and phase: Superfluid density in disordered superconductors
Sudhansu S. Mandal, T. V. Ramakrishnan
Recent experiments on disordered superconductors find that the superfluid density decreases dramatically and characteristically with disorder, differently from what is exp…
Ginzburg-Landau Like Theory for High Temperature Superconductivity in the Cuprates: Emergent d-wave Order
T. V. Ramakrishnan
High temperature superconductivity in the cuprates remains one of the most widely investigated, constantly surprising, and poorly understood phenomena in physics. Here, we describe…
Phenomenological Ginzburg-Landau-like theory for superconductivity in the cuprates
Sumilan Banerjee, T. V. Ramakrishnan, Chandan Dasgupta
We propose a phenomenological Ginzburg-Landau-like theory of cuprate superconductivity. The free energy is expressed as a functional F of the spin-singlet pair amplitude psi_ij=psi…
Ground State Vortex Lattice Structures in d-wave Superconductors
Sudhansu S. Mandal, T. V. Ramakrishnan
We show in a realistic symmetry gap model for a cuprate superconductor that the clean vortex lattice has discontinuous structural transitions (at and near T=0), a…
Effective Actions and Phase Fluctuations in d-wave Superconductors
Arun Paramekanti, Mohit Randeria, T. V. Ramakrishnan +1
We study effective actions for order parameter fluctuations at low temperature in layered d-wave superconductors such as the cuprates. The order parameter lives on the bonds of a s…
