TLDR
It is argued that, in the presence of charge ordering, a nonmonotonic behavior with decreasing temperature is possible with a maximum in the resistance just before entering the superconducting phase.

TLDR
The Ginzburg-Landau functional for a superconductor is extended to include a quantum-fluctuation term arising from imperfect screening of the long-range Coulomb interaction and it is shown that the phase stiffness is proportional to doping away from the 1/2-full Mott insulating state.

TLDR
The value of the superconducting critical temperature of artificially layered superconductor layers is calculated as a function of both the number of layers of pure Y-Ba-Cu-O within a unit cell of thesuperlattice and the thickness of the insulating layer.
Instability of granular superconductivity

TLDR
A reentrant transition is found to exist for moderate quantum fluctuations; it persists regardless of the ratio of the junction capacitance to the self-capacitance although the junction capacitor tends to suppress the reduction of the transition temperature due to quantum fluctuations.
Collective mode and the c-axis critical current of a Josephson-coupled superconductor at high parallel magnetic fields.
TLDR
Using Maxwell and time-dependent Ginzburg-Landau equations in the framework of a Lawrence-Doniach model, the dispersion relation and relaxation rate of collective modes in the absence of a magnetic field and in a strong parallel magnetic field is obtained.
