Electronic properties and surface states of RbNiSe
Surajit Basak, Przemysław Piekarz, Andrzej Ptok
Iron-based superconductors, with the ThCrSi-type tetragonal structure (122 family), due to the iron arsenide/selenide layers exhibit several characteristic electronic p…
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$_…
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…
The ab initio study of unconventional superconductivity in CeCoIn and FeSe
Andrzej Ptok, Konrad J. Kapcia, Przemysław Piekarz +1
Electronic structure and the shape of the Fermi surface are known to be of fundamental importance for the superconducting instability in real materials. We demonstrate that such an…
Magnetic Lifshitz transition and its consequences in multi-band iron-based superconductors
Andrzej Ptok, Konrad J. Kapcia, Agnieszka Cichy +2
In this paper we address Lifshitz transition induced by applied external magnetic field in a case of iron-based superconductors, in which a difference between the Fermi level and t…
