Using Inhomogeneity to Raise Superconducting Critical Temperatures
Y. L. Loh, E. W. Carlson
Superconductors with low superfluid density can be described by XY models. In such models the scale of the transition temperature T_c is largely set by the zero temperature phase s…
Effect of Spin Fluctuations on Phonon-Mediated Superconductivity in the Vicinity of a Quantum Critical Point
Y. L. Loh, P. B. Littlewood
We consider an s-wave superconductor in the vicinity of a second-order ferromagnetic (FM) or spin-density-wave (SDW) quantum critical point (QCP), where the superconductivity and m…
"Exact" Algorithm for Random-Bond Ising Models in 2D
Y. L. Loh, E. W. Carlson
We present an efficient algorithm for calculating the properties of Ising models in two dimensions, directly in the spin basis, without the need for mapping to fermion or dimer mod…
Optical conductivity of a granular metal at not very low temperatures
V. Tripathi, Y. L. Loh
We study the finite-temperature optical conductivity, sigma(omega,T), of a granular metal using a simple model consisting of a array of spherical metallic grains. It is necessary t…
