When Andreev bound states are formed at the surfaces of a superconducting film, there may arise, as the ground state of the film, a superconducting state with broken time-reversal symmetry ( $$\mathcal {T}$$ ). In this state, Cooper pairs with a fini

We report a theoretical study on the phase transition between superconducting states with and without spontaneous surface current. The phase transition takes place due to the formation of surface Andreev bound states in unconventional superconductors

We propose a mechanism that helps stabilize a superconducting state with broken time-reversal symmetry, which was predicted to realize in a d-wave superconducting film [A. B. Vorontsov, Phys. Rev. Lett. 102, 177001 (2009)]. In this superconducting ph

A theoretical study is presented on the effect of anion order on the phase transition from the normal state to a Fulde–Ferrell–Larkin –Ovchinnikov superconducting state in a quasi-one-dimensional organic superconductor (TMTSF)2ClO4. The tempera

The normal-superconducting phase transition in d-wave superconducting films is discussed with a focus on the effect of diffuse surface scattering. A specularity parameter S characterizing the boundary condition is introduced for systematic analysis o

The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state is examined in quasi-one-dimensional s-wave and d-wave superconductors with particular attention paid to the effect of the Fermi-surface anisotropy. The upper critical field $H_{c2}(T)$ is found to ex

We investigate the effect of a rough surface on the normal-superconducting phase transition in d-wave superconducting films on the basis of the quasiclassical theory of superconductivity with a boundary condition that allows us to treat the surface s

We report a theoretical study of the critical thickness for a broken time-reversal state that may arise in d-wave superconducting films. By examining the effect of the Fermi surface shape on the critical thickness on the basis of a square lattice tig
