Broken symmetry driven topological semi-metal to gaped phase transitions in SrAgAs
Chiranjit Mondal, C. K. Barman, Aftab Alam +1
We show the occurence of Dirac, Triple point, Weyl semimetal and topological insulating phase in a single ternary compound using specific symmetry preserving perturbations. Based o…
Quaternary Heusler Alloy: An Ideal Platform to Realize Triple Point Fermion
C. K. Barman, Chiranjit Mondal, Biswarup Pathak +1
The existence of three fold rotational, mirror and time reversal symmetries often give rise to the triply degenerate nodal point (TP) in the band structure of a material. Based on…
Revealing the nature of antiferro-quadrupolar ordering in Cerium Hexaboride: CeB
Chanchal Barman, Prashant Singh, Duane D. Johnson +1
Cerium-hexaboride (CeB) f-electron compound displays a rich array of low-temperature magnetic phenomena, including `magnetically hidden' order, identified as multipolar in orig…
Topological Nontrivial Phase in Hexagonal Antiperovskites A3BiB (A=Ba,Sr; B=P,N)
C. K. Barman, Chiranjit Mondal, Vijay Singh +2
In this article, we predict the occurrence of topological non-trivial phase in hexagonal antiperovskite systems. By carefully investigating the evolution of band structure, we have…
Emergence of Topological insulator and Nodal line semi-metal states in XX'Bi (X=Na, K, Rb, Cs; X'=Ca, Sr)
Chiranjit Mondal, C. K. Barman, Sourabh Kumar +2
In this letter, we predict the emergence of non-trivial band topology in the family of XX'Bi compounds having (\# 189) space group. Using first principles calcula…
