Anisotropy in the helicity modulus of a quantum 3D XY-model: application to YBCO
B. Mitrovic, K. Samokhin, S. K. Bose
We present a variational study of the helicity moduli of an anisotropic quantum three-dimensional (3D) XY-model of YBCO in superconducting state. It is found that both the ab-plane…

Nodal quasiparticles and classical phase fluctuations in d-wave superconductors
K. V. Samokhin, B. Mitrovic
We show that the nodal quasiparticles have significant effect on the classical phase fluctuations in a quasi-two-dimensional d-wave superconductor. They give rise to singularities…

Anisotropy in the helicity modulus of a 3D XY-model: application to YBCO
B. Mitrovic, S. K. Bose, K. Samokhin
We present a Monte Carlo study of the helicity moduli of an anisotropic classical three-dimensional (3D) XY-model of YBCO in superconducting state. It is found that both the ab-pla…
