Strain induced stabilization of high symmetry phase in MAPbBr3 perovskite
Shankar Dutt, Joydipto Bhattacharya, Kailash Kumar +3
Structural phase transitions in the organic inorganic metal halide perovskites are driven via rearrangement of methylammonium cation and distortion in the PbX6 octahedra. Compositi…
Kramers nodal line in the charge density wave state of YTe and the influence of twin domains
Shuvam Sarkar, Joydipto Bhattacharya, Pramod Bhakuni +13
Recent studies have focused on the relationship between charge density wave (CDW) collective electronic ground states and nontrivial topological states. Using angle-resolved photoe…
Growth of bilayer stanene on a magnetic topological insulator aided by a buffer layer
Sajal Barman, Pramod Bhakuni, Shuvam Sarkar +10
Stanene, a two-dimensional counterpart to graphene, has the potential to exhibit novel quantum phenomena when grown on a magnetic topological insulator (MTI). This work demonstrate…

Charge density wave induced nodal lines in LaTe
Shuvam Sarkar, Joydipto Bhattacharya, Pampa Sadhukhan +11
LaTe is a noncentrosymmetric (NC) material with time reversal (TR) symmetry in which the charge density wave (CDW) is hosted by the Te bilayers. Here, we show that LaTe hos…
