Rustem Khasanov, Zurab Guguchia, Elvezio Morenzoni +5
The magnetic properties of iron-based superconductors FeAs (K, Cs, and Rb), which are characterized by the V-shaped dependence of the critical temperature ($T_{\rm c…
Two-gap to Single-gap Superconducting Transition on a Honeycomb Lattice in CaSrAlSi
Dorota I. Walicka, Zurab Guguchia, Jorge Lago +4
It is a well-established fact that the physical properties of compounds follow their crystal symmetries. This has especially pronounced implications on emergent collective quantum…
