TL;DR: Experimental evidence is reported for magnetic Weyl fermions in Mn3Sn, a non-collinear antiferromagnet that exhibits a large anomalous Hall effect, even at room temperature, and lays the foundation for a new field of science and technology involving the magnetic Wey excitations of strongly correlated electron systems such as Mn3 Sn.
Journal ArticleDOI
Giant anomalous Nernst effect and quantum-critical scaling in a ferromagnetic semimetal
Akito Sakai,Yo Pierre Mizuta,Agustinus Agung Nugroho,Agustinus Agung Nugroho,Rombang Sihombing,Rombang Sihombing,Takashi Koretsune,Michi-To Suzuki,Nayuta Takemori,Rieko Ishii,Daisuke Nishio-Hamane,Ryotaro Arita,Pallab Goswami,Pallab Goswami,Satoru Nakatsuji +14 more
TL;DR: In this paper, the authors reported the observation of a giant anomalous Nernst effect at room temperature in the full-Heusler ferromagnet Co2MnGa, an order of magnitude larger than the previous maximum value reported for a magnetic conductor.
Journal ArticleDOI
Axionic field theory of (3+1)-dimensional Weyl semimetals
Pallab Goswami,Sumanta Tewari +1 more
TL;DR: In this article, an axionic field theory with a nonquantized coefficient describes the electromagnetic response of the $(3+1)$-dimensional Weyl semimetal, where the coefficient is proportional to the momentum space separation of the Weyl nodes.
Journal ArticleDOI
Quantum criticality between topological and band insulators in $(3+1)$-dimensions
Pallab Goswami,Sudip Chakravarty +1 more
TL;DR: Four-component massive and massless Dirac fermions in the presence of long range Coulomb interaction and chemical potential disorder exhibit striking fermionic quantum criticality.
