Revealing the intrinsic electronic structure and complex fermiology of YRu2Si2 using angle-resolved photoemission spectroscopy
Anup Pradhan Sakhya, Sabin Regmi, Milo Sprague +6
We performed a detailed study of the intrinsic electronic structure of YRu2Si2 employing angleresolved photoemission spectroscopy (ARPES) and density-functional theory (DFT) based…
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…
Lattice dynamics study of electron-correlation-induced charge density wave in antiferromagnetic kagome metal FeGe
Andrzej Ptok, Surajit Basak, Aksel KobiaÅka +5
Electron-correlation-driven phonon soft modes have been recently reported in the antiferromagnetic kagome FeGe compound and associated with the observed charge density wave (CDW).…
Evidences for local non-centrosymmetricity and strong phonon anomaly in EuCu2As2: A Raman spectroscopy and lattice dynamics study
Debasmita Swain, Mainak Dey Sarkar, Andrzej Ptok +3
Phonon modes and their association with the electronic states have been investigated for the metallic EuCuAs system. In this work, we present the Raman spectra of this…
