چکیده
Superconducting transition metal dichalcogenides emerged as a prime candidate for topological superconductivity. This work presents detailed investigation of superconducting and transport properties on 2H-TaSeS single crystals using magnetization, transport, specific heat measurements. These measurements suggest multigap anisotropic superconductivity with the upper critical field, breaking Pauli limiting field in both in-plane out-of-plane directions. The angle dependence suggests 2-dimensional nature bulk 2H- TaSeS.

Superconductivity in the two-dimensional Hubbard model.
A refined variational wave function for the two-dimensional repulsive Hubbard model is studied numerically , with the aim of approaching the difficult crossover regime of intermediate values of U. The issue of a superconducting ground state with d-wave symmetry is investigated for an average electron density n ≈ 0.8 and for U = 8t. Due to finite-size effects a clear-cut answer to this fundament...
متن کاملPairing superconductivity in two-dimensional CuO2.
The strongly correlated two-dimensional Cu0& layer is studied to identify the mechanism of possible pairing superconductivity. The correlative motions of 0 and Cu holes are treated by a reasonable mean-field theory, and we find that holes on oxygen sites couple strongly to Cu holes to form Cu-0 spin singlet pairs, which in turn interact strongly with the Cu resonating-valence-bond state and lea...

متن کاملFidelity and superconductivity in two-dimensional t-J models
We compute the ground-state fidelity and various correlations to gauge the competition between different orders in two-dimensional t-J-type models. Using exact numerical diagonalization techniques, these quantities are examined for i the plain t-J and t-t -J models, ii for the t-J model perturbed by infinite-range d-wave or extended-s-wave superconductivity inducing terms, and iii the t-J model...
