A Unified Theory of Collective Magnon and Orbiton Excitations in Altermagnets
Bishal Das, Chanchal K. Barman, Aftab Alam
Altermagnetism has recently emerged as a distinct collinear magnetic phase exhibiting momentum-dependent spin-splitting despite vanishing net magnetization, as a consequence of ine…
Topological Weyl Phase of an Ideal Spin-Gapless Semiconductor KCrSe
Subhajit Mandal, Bishal Das, Himanshu Sharma +2
The coexistence of topological and spin-polarized electronic states within a single material platform provides an attractive route toward emergent quantum phenomena and spintronic…
Topological Surface States and Anisotropic Magnetotransport in SnSbTe
Mohit Mudgal, Subhajit Mandal, Bishal Das +11
We have investigated the electronic structure and magnetotransport properties of SnSbTe single crystals using density functional theory (DFT), synchrotron-based angle-re…
The Fundamental Lemma of Altermagnetism: Emergence of Alterferrimagnetism
Chanchal K. Barman, Bishal Das, Alessio Filippetti +2
Recent years have seen a proliferation in investigations on Altermagnetism due to its exciting prospects both from an applications perspective and theoretical standpoint. Tradition…
Intrinsic Berry Curvature Driven Anomalous Hall and Nernst Effect in CoMnSn
Bishal Das, Arnab Bhattacharya, Amit Chanda +5
Magnetic topological semimetals often exhibit unusual electronic and thermal transport due to nontrivial bulk band crossings, enabling simultaneous realization of large anomalous H…
