PARPHOM: PARallel PHOnon calculator for Moiré systems
Shinjan Mandal, Indrajit Maity, H R Krishnamurthy +1
The introduction of a twist between two layers of two-dimensional materials has opened up a new and exciting field of research known as twistronics. In these systems, the phonon di…
Phonon Linewidths in Twisted Bilayer Graphene near Magic Angle
Shinjan Mandal, Indrajit Maity, H. R. Krishnamurthy +1
We present a computational study of the phonon linewidths in twisted bilayer graphene arising from electron-phonon interactions and anharmonic effects. The electronic structure is…
Valley-polarized Exitonic Mott Insulator in WS2/WSe2 Moiré Superlattice
Zhen Lian, Yuze Meng, Lei Ma +14
Strongly enhanced electron-electron interaction in semiconducting moiré superlattices formed by transition metal dichalcogenides (TMDCs) heterobilayers has led to a plethora of int…
Influence of atomic relaxations on the moiré flat band wavefunctions in antiparallel twisted bilayer WS
Laurent Molino, Leena Aggarwal, Indrajit Maity +3
Twisting bilayers of transition metal dichalcogenides (TMDs) gives rise to a periodic moiré potential resulting in flat electronic bands with localized wavefunctions and enhanced c…
Anharmonicity in Raman-active phonon modes in atomically thin MoS
Suman Sarkar, Indrajit Maity, H. L. Pradeepa +10
Phonon-phonon anharmonic effects have a strong influence on the phonon spectrum; most prominent manifestation of these effects are the softening (shift in frequency) and broadening…
Origin and Evolution of Ultraflatbands in Twisted Bilayer Transition Metal Dichalcogenides: Realization of Triangular Quantum Dot Array
Mit H. Naik, Sudipta Kundu, Indrajit Maity +1
Using a multiscale computational approach, we probe the origin and evolution of ultraflatbands in moiré superlattices of twisted bilayer MoS, a prototypical transition metal di…
