Strong-coupling superconductivity of SrIr2 and SrRh2: Phonon engineering of metallic Ir and Rh
Sylwia Gutowska, Karolina Górnicka, Paweł Wójcik +2
Experimental and theoretical studies on superconductivity in SrIr and SrRh Laves phases are presented. The measured resistivity, heat capacity, and magnetic susceptibility…
Impact of the spin-orbit interaction on the phase diagram and anisotropy of the in-plane critical magnetic field in superconducting LaAlO/SrTiO interface
P. Wójcik, M. P. Nowak, M. Zegrodnik
The two-dimensional electron gas at the interface between LaAlO and SrTiO (LAO/STO) exhibits gate tunable superconductivity with a characteristic dome-like shape of the cri…
Helical and topological phase detection based on nonlocal conductance measurements in a three terminal junction
P. Wójcik, D. Sticlet, P. Szumniak +1
The helical state is a fundamental prerequisite for many spintronics applications and Majorana zero mode engineering in nanoscopic semiconductors. Its existence in quasi-one-dimens…
Electronic structure, electron-phonon coupling and superconductivity in noncentrosymmetric ThCoC2 from ab initio calculations
Gabriel Kuderowicz, Paweł Wójcik, Bartlomiej Wiendlocha
Superconductors without inversion symmetry in their crystal structure are known to exhibit unconventional properties. Recently, based on the measured temperature dependence of the…

The two-dimensional electron gas (2DEG) at the LaAlO/SrTiO interface exhibits gate tunable superconductivity with a domelike shape of as a function of electron…
Superconducting dome in doped 2D superconductors with broken inversion symmetry
P. Wójcik, M. P. Nowak, M. Zegrodnik
We analyze an unconventional inter-subband paired phase in a 2D doped superconductor considering both systems with the inversion symmetry and with the inversion symmetry broken. We…
Symmetry of Birkhoff-James orthogonality of operators defined between infinite dimensional Banach spaces

We study left symmetric bounded linear operators in the sense of Birkhoff-James orthogonality defined between infinite dimensional Banach spaces. We prove that a bounded linear ope…
