Topological in-gap chiral edge states in superconducting Haldane model with spin-orbit coupling
Sajid Sekh, Andrzej Ptok
Topological superconductivity is currently one of the prime interests, given the properties of its exotic nature of chiral edge states. A broken time-reversal symmetry (TRS) is an…
Comment on "Fully gapped superconductivity and topological aspects of the noncentrosymmetric superconductor TaReSi"
Andrzej Ptok
In a recent paper [T. Shang et al., Phys. Rev. B 107, 224504 (2023)], the authors study the physical properties of TaReSi compounds having Ima2 structure. This noncentrosymmetric s…
Spin-polarized superconducting phase in semiconducting system with next-nearest-neighbor hopping on the honeycomb lattice
Agnieszka Cichy, Konrad J. Kapcia, Andrzej Ptok
The particles in the honeycomb lattice with on-site -wave pairing exhibit many interesting behaviors, which can be described in the framework of the Hubbard model. Among others,…
Theoretical study of dynamical and electronic properties of noncentrosymmetric superconductor NbReSi
Surajit Basak, Andrzej Ptok
The noncentrosymmetric NbReSi superconductor with K is characterized by the relatively large upper critical magnetic field. Its multigap features were observed e…
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…
Majorana bound states in the presence of the half-smeared potential
Surajit Basak, Andrzej Ptok
The Majorana bound state can be realized in one dimensional chain, in form of two well localized and separated states at both ends of the chain. In this paper, we discuss the case…
