Reciprocity between local moments and collective magnetic excitations in the phase diagram of BaFe(AsP)
Jonathan Pelliciari, Kenji Ishii, Yaobo Huang +12
Unconventional superconductivity arises at the border between the strong coupling regime with local magnetic moments and the weak coupling regime with itinerant electrons, and stem…
A new Berry phase term in parity-time symmetric non-Hermitian spin-1/2 quantum systems
Ananya Ghatak, Tanmoy Das
Recently developed parity () and time-reversal () symmetric non-Hermitian quantum theory is envisioned to have far-reaching implications in basic science…
Spin-orbit driven spin depolarization in the ferromagnetic Weyl semimetal Co3Sn2S2
Sandeep Howlader, Surabhi Saha, Ritesh Kumar +4
CoSnS has recently emerged as a ferromagnetic Weyl semi-metal. Theoretical investigation of the spin-split bands predicted half metalicity in the compound. Here, we rep…
Anomalous electron transport in epitaxial NdNiO films
Shashank Kumar Ojha, Sujay Ray, Tanmoy Das +8
The origin of simultaneous electronic, structural and magnetic transitions in bulk rare-earth nickelates (NiO) remains puzzling with multiple conflicting reports on the nat…
Novel attractive pairing interaction in strongly correlated superconductors
Priyo Adhikary, Tanmoy Das
Conventional and unconventional superconductivity, respectively, arise from attractive (electron-phonon) and repulsive (many-body Coulomb) interactions with fixed-sign and sign-rev…
Investigation of Superconducting Gap Structure in HfIrSi using muon spin relaxation/rotation
A. Bhattacharyya, K. Panda, D. T. Adroja +6
Appearance of strong spin-orbit coupling (SOC) is apparent in ternary equiatomic compounds with 5-electrons due to the large atomic radii of transition metals. SOC plays a signi…
