Effect of polar distortions on the linear and nonlinear anomalous Hall conductivity of altermagnetic -MnTe
Mathews Benny, Sahar Izadi Vishkayi, Amar Fakhredine +2
Altermagnetic -MnTe with Néel vector along the -axis exhibits a finite anomalous Hall conductivity (AHC) and weak ferromagnetism along the -axis. As already demonstrated i…
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 Nonlinear Planar Thermal Hall Effect
Chanchal K. Barman
We introduce the intrinsic nonlinear planar thermal Hall effect (NPTHE)-- a dissipationless thermal response proportional to , which arises when the temperature grad…
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…
Coexistence of Multifold and Multidimensional Topological Phonons in KMgBO
P. C. Sreeparvathy, Chiranjit Mondal, Chanchal K. Barman +1
Topological interpretations of phonons facilitate a new platform for novel concepts in phonon physics. Though there are ubiquitous set of reports on topological electronic excitati…
Intertwined non-trivial band topology and giant Rashba spin splitting
Chiranjit Mondal, Chanchal K. Barman, Aftab Alam +1
Composite quantum compounds (CQCs) have become an important avenue for the investigation of inter-correlation between two distinct phenomenon in physics. Topological superconductor…
Co-existence of Topological Non-trivial and Spin Gapless Semiconducting Behavior in MnPO: A Composite Quantum Compound
Chia-Hsiu Hsu, P. C. Sreeparvathy, Chanchal K. Barman +2
Composite quantum compounds (CQC) are classic example of quantum materials which host more than one apparently distinct quantum phenomenon in physics. Magnetism, topological superc…
Symmetry driven topological phases in XAgBi (X=Ba,Sr): An Ab-initio hybrid functional calculations
Chanchal K. Barman, Chiranjit Mondal, Biswarup Pathak +1
Density functional theory (DFT) approaches have been ubiquitously used to predict topological order and non-trivial band crossings in real materials, like Dirac, Weyl semimetals an…
Symmetry protection and giant Fermi arcs from multifold fermions in binary, ternary, and quaternary compounds
Chanchal K. Barman, Chiranjit Mondal, Sumiran Pujari +2
Higher-fold chiral fermions that go beyond two-fold Weyl fermions have recently been reported in crystalline systems. Here, we focus on such excitations in several binary, ternary…

We predict three full Heusler compounds XInPd2 (X = Zr, Hf and Ti) to be potential candidates for type-II Dirac semimetals. The crystal symmetry of these compounds have appropriate…
Unique Dirac and Triple point fermiology in simple transition metals and their binary alloys
Chiranjit Mondal, Chanchal K. Barman, Shuvam Sarkar +3
Noble metal surfaces (Au, Ag and Cu etc.) have been extensively studied for the Shockley type surface states (SSs). Very recently, some of these Shockley SSs have been understood f…
