Observation of a Novel Charge Density Wave Superstructure in Monolayer 1T- at Room Temperature and its Evolution in Multilayers
Samanta Pal, Kaustuv Chatterjee, Jyotirmoy Sau +4
Spontaneous formation of charge density wave (CDW) superstructures in monolayers (MLs) of a two-dimensional (2D) crystal lattice is fundamental in understanding its complex quantum…

Polarization-Driven Charge Frustration and Emergent Phases in the One-Dimensional Extended Hubbard Model
Sourabh Saha, Jeroen van den Brink, Manoranjan Kumar +1
Frustration is a key driver of exotic quantum phases, yet its role in charge dynamics remains largely unexplored. We show that charge frustration - induced by electronic polarizati…

Phase diagram of a coupled trimer system at half filling using the Hubbard model
Sourabh Saha, Hosho Katsura, Manoranjan Kumar
Flat band systems have recently attracted significant attention due to their instability under small perturbations, which can lead to the stabilization of many exotic quantum phase…
