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…
Emergent scalar-chirality \& colossal transverse-magnetoresponse in strongly correlated nodal-line half-metal
Jyotirmoy Sau, Sourav Chakraborty, Sourabh Saha +3
Understanding the interplay of strong correlation and temperature in nodal-line semimetals can offer novel ways to control spin currents. Here we consider the 3d-5d double-perovski…
Exploring magnetic and topological complexity in MgMnSn: from frustrated ground states to nontrivial Hall conductivity
Jyotirmoy Sau, Hrishit Banerjee, Sourabh Saha +2
We explore the intriguing topological itinerant magnet MgMnSn, characterized by bilayer kagome Mn layers encasing a hexagonal Sn layer. Using \textit{ab initio} Density fun…
