Nanoscale Electronic Phase Separation Driven by Fe-site Ordering in Fe\textsubscript{5-x}GeTe\textsubscript{2}
Shreyashi Sinha, Ayan Jana, Suchanda Mondal +3
Understanding how local structural order governs electronic correlations is essential for revealing the microscopic mechanism underlying emergent behavior in two-dimensional magnet…
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…
Accessing quasi-flat -bands to harvest large Berry curvature in NdGaSi
Anyesh Saraswati, Jyotirmoy Sau, Vera Misheneva +10
In typical rare-earth lanthanide compounds, the localized 4\textit{f}-electrons have a weak effect on the electrical conduction, limiting their influence on the Berry curvature and…
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…
Tuning intrinsic anomalous Hall effect from large to zero in two ferromagnetic states of SmMn2Ge2
Mahima Singh, Jyotirmoy Sau, Banik Rai +3
The intrinsic anomalous Hall conductivity (AHC) in a ferromagnetic metal is completely determined by its band structure. Since the spin orientation direction is an important band-s…
