First-principles investigation of topological phase in rare-earth compounds

Wadhwa, P. (2020-11-26)

Topological insulators (TIs) have attracted scienti c community in recent years owing to their remarkable physical properties like bulk band inversion and exotic surface states. In recent years, the search for novel ...
Non-trivial band topology in Bi doped Lanthanum monopnictides (LaX; X = As and Sb)

Wadhwa, P.; Dhilip Kumar, T.J.; Shukla, A.; Kumar, R. (2022-12-10)

In this study, we report first-principles investigation of non-trivial topological characteristics in Bi doped Lanthanum monopnictides, particularly LaAs and LaSb. For this, we varied the concentration of Bi atoms in 1 × ...
Studies of non-trivial band topology and electron-hole compensation in YSB

Wadhwa, Payal; Kumar, Shailesh; Shukla, Alok; Kumar, Rakesh (2020-09-29)

In this article, we study non-trivial topological phase and electron-hole compensation in extremely large magnetoresistance (XMR) material YSb under hydrostatic pressure using first-principles calculations. YSb is topologically ...
