Multiple correlation lengths and type-1.5 superconductivity in superconductors due to hidden competition between irreducible representations of nonlocal pairing
Anton Talkachov, Paul Leask, Egor Babaev
A fundamental characteristic of a superconducting state is the coherence length . Multicomponent superconductors, particularly ones breaking multiple symmetries, are characteri…

Microscopic theory of strain-controlled split superconducting and time-reversal symmetry-breaking transitions in superconductor
Anton Talkachov, Egor Babaev
We study conditions of the appearance of superconducting states that spontaneously break time-reversal symmetry (BTRS) on a square lattice as a function o…

A microscopic approach to the problem of enhancement and suppression of superconductivity on twinning planes
Anton Talkachov, Sahal Kaushik, Egor Babaev
Using a microscopic approach, we revisit the problem of superconducting critical temperature change in the presence of twin boundaries. We show that both critical temperature enhan…
