Though YB6 and LaB6 share the same crystal structure, atomic valence electron
configuration, and phonon modes, they exhibit drastically different phonon-mediated …

The intensive development of hydrogen technologies has made very promising applications
of one of the cheapest and easily produced bulk MgB2-based superconductors. These …

Weyl semimetals have nodes in their electronic structure at which electrons attain a definite
chirality. Due to the chiral anomaly, the nonconservation of charges with given chirality, the …

We analyze a bubble-forming system composed of particles with competing long-range
repulsive and short-range attractive interactions driven over a quasi-one-dimensional …

It has been proposed that two-band superconductors exhibit a distinct phase characterized
by two correlation lengths, where one is smaller and the other larger than the magnetic field …

We discuss the instability of uniform superconducting states that contain the pairing
correlations belonging to the odd-frequency symmetry class. The instability originates from …

In this work, we study the proximity effects in a single-and two-band superconducting three-
dimensional heterostructure, described by two condensates (condensate 1 and condensate …

Abstract (EN) This thesis concentrates on the effect of Lifshitz transitions and associated Van
Hove singularities on the superconducting state of Sr₂RuO₄. I will start by giving a short …

超伝導とは, 極低温で起こる巨視的量子現象の一つである. 超伝導体は物質固有の転移温度を境に
, 電気抵抗の消失や, 試料内部から磁場を排斥する Meissner 効果といった …
