Multigap superconductivity in Ising superconductors: The case of (LaSe)1.14(NbSe2)m misfit layer compounds

Alexandra Palacio-Morales, Tomáš Samuely, Ludovica Zullo, Raphaël Leriche et autres

Strong spin-orbit coupling and broken inversion symmetry in transition metal dichalcogenides give rise to Ising superconductivity, a spin-protected pairing state first identified in monolayer NbSe$_2$ through in-plane critical fields far exceeding the Pauli limit. More recently, Ising superconductivity has been proposed as …

Band-Selective Tunneling and Anisotropic Multiband Superconductivity in V$_2$Ga$_5$

Jozef Haniš, Jozef Kačmarčík, Filip Košuth, Levente Faber et autres

Multiband superconductors with structural anisotropy offer a fertile ground for exploring unconventional quantum states, yet disentangling their directional pairing characteristics remains a formidable challenge. Here, we present a comprehensive thermodynamic and spectroscopic study of the tetragonal intermetallic superconductor $\text{V}_2\text{Ga}_5$ ($T_{\rm c} \approx …

Direct evidence for two-gap superconductivity in hydrogen-intercalated titanium diselenide

Erik Piatti, Gaia Gavello, Giovanni Alberto Ummarino, Filip Košuth et autres

Transition-metal dichalcogenides (TMDs) offer an extremely rich material platform in the exploration of unconventional superconductivity. The unconventional aspects include exotic coupling mechanisms such as the Ising pairing, a complex interplay with other electronic orders such as charge-density waves (CDWs), symmetry-breaking and topological …

Two-gap superconductivity in the noncentrosymmetric La$_3$Se$_4$ compound

F. Košuth, N. Potomová, Z. Pribulová, J. Kačmarčík et autres

Point-contact Andreev reflection spectroscopy at low temperatures and high magnetic fields has been performed on a noncentrosymmetric La$_3$Se$_4$ superconductor with a critical temperature $T_c$ = 8 K. Two superconducting energy gaps $Δ_1$ and $Δ_2$ with $2Δ_{1}/k_{B} T_{c}$ ~ 5.8 and $2Δ_{2}/k_{B} T_{c}$ …
