Low-Temperature Phase of the CdReO Superconductor: Ab initio Phonon Calculations and Raman Scattering
Konrad J. Kapcia, Maureen Reedyk, Mojtaba Hajialamdari +5
Using an {\it ab initio} approach, we report a phonon soft mode in the tetragonal structure described by the space group of the K superconductor CdReO$_…
Electronic and lattice properties of non-centrosymmetric superconductors ThTSi (T = Co, Ir, Ni, and Pt)
A. Ptok, K. Domieracki, K. J. Kapcia +5
The theoretical studies on the electronic and lattice properties of the series of non-centrosymmetric superconductors ThTSi, where T = Co, Ni, Ir, and Pt are presented. The electro…
Phase separations induced by a trapping potential in one-dimensional fermionic systems as a source of core-shell structures
Agnieszka Cichy, Konrad Jerzy Kapcia, Andrzej Ptok
Ultracold fermionic gases in optical lattices give a great opportunity for creating different types of novel states. One of them is phase separation induced by a trapping potential…
Structural, electronic, and dynamical properties of the tetragonal and collapsed tetragonal phases of KFeAs
Andrzej Ptok, Małgorzata Sternik, Konrad Jerzy Kapcia +1
Compounds with a tetragonal ThCrSi-type structure are characterized by the possibility of the isostructural phase transition from the tetragonal phase to the collapsed…
Extended Falicov-Kimball model: Exact solution for finite temperatures
Konrad Jerzy Kapcia, Romuald Lemański, Stanisław Robaszkiewicz
The extended Falicov-Kimball model is analyzed exactly for finite temperatures () in the limit of large dimensions. Onsite and intersite density-density interactions an…
