Semi-Dirac spin liquids and frustrated quantum magnetism on the trellis lattice
Sourin Chatterjee, Atanu Maity, Janik Potten +7
Geometrical frustration in quantum magnets provides a fertile setting for unconventional phases of matter, including quantum spin liquids (QSLs). The trellis lattice, with its comp…
Topological phase transition in anti-symmetric Lotka-Volterra doublet chain
Rukmani Bai, Sourin Chatterjee, Ujjwal Shekhar +3
We present the emergence of topological phase transition in the minimal model of two dimensional rock-paper-scissors cycle in the form of a doublet chain. The evolutionary dynamics…
How Combined Pairwise and Higher-Order Interactions Shape Transient Dynamics
Sourin Chatterjee, Sayantan Nag Chowdhury
Understanding how species interactions shape biodiversity is a core challenge in ecology. While much focus has been on long-term stability, there is rising interest in transient dy…
Fairness, not Emotion, Drives Socioeconomic Decision Making
Rudra Mukhopadhyay, Sourin Chatterjee, Koel Das
Emotion and fairness play a key role in mediating socioeconomic decisions in humans; however, the underlying neurocognitive mechanism remains largely unknown. This exploratory stud…
