A term first coined by Mott back in 1968 a “pseudogap” is the depletion of the electronic
density of states at the Fermi level, and pseudogaps have been observed in many systems …

The phase diagram for a general model for cuprates is derived in a mean-field
approximation. A phase-violating time reversal without breaking translational symmetry is …

NaSn 2 P 2 is a recently discovered superconducting system belonging to a particular class
of materials with van der Waals (vdW) structure. There is enormous interest in vdW …

The universality of the strange metal phase in many quantum materials is often attributed to
the presence of a quantum critical point (QCP), a zero-temperature phase transition ruled by …

For any practical superconductor the magnitude of the critical current density, J c, is crucially
important. It sets the upper limit for current in the conductor. Usually J c falls rapidly with …

We show theoretically that phase and amplitude fluctuations set in simultaneously in the
cuprates. We then analyze fluctuations about T c in the specific heat of (Y, Ca) Ba 2 Cu 3 O 7 …

The confrontation between percolation processes and superconducting fluctuations to
account for the observed enhanced in-plane electrical conductivity above but near T c in …

The effect of the partial substitution of Ca 2+ by Ho 3+ ions on the electrical and mechanical
properties of the superconducting phase (Bi, Pb)-2223 was studied. Superconducting …
