From dimensional reduction to tetramerization in mixed ferro-antiferro breathing pyrochlores
Sourin Chatterjee, Kelvin Salou-Smith, Benedikt Schneider +8
We study the spin-1/2 nearest-neighbor Heisenberg model on the breathing pyrochlore lattice in the mixed ferro-antiferromagnetic regime, where one tetrahedral sublattice is antifer…
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…
A First Principles Approach to Trust-Based Recommendation Systems in Social Networks
Paras Stefanopoulos, Sourin Chatterjee, Ahad N. Zehmakan
This paper explores recommender systems in social networks which leverage information such as item rating, intra-item similarities, and trust graph. We demonstrate that item-rating…
A Novel Room-Based Epidemic Model: Quarantine, Testing, and Vaccination Strategies
Sourin Chatterjee, Ahad N. Zehmakan, Sujay Rastogi
Epidemic outbreaks pose significant challenges to public health and socio-economic stability, necessitating a comprehensive understanding of disease transmission dynamics and effec…
Neighbour Sum Patterns : Chessboards to Toroidal Worlds
Sayan Dutta, Ayanava Mandal, Sohom Gupta +1
We say that a chessboard filled with integer entries satisfies the neighbour-sum property if the number appearing on each cell is the sum of entries in its neighbouring cells, wher…
Effective Vaccination Strategies in Network-based SIR Model
Sourin Chatterjee, Ahad N. Zehmakan
Controlling and understanding epidemic outbreaks has recently drawn great interest in a large spectrum of research communities. Vaccination is one of the most well-established and…
Characterising Solutions of Anomalous Cancellation
Satvik Saha, Sohom Gupta, Sayan Dutta +1
Anomalous cancellation of fractions is a mathematically inaccurate method where cancelling the common digits of the numerator and denominator correctly reduces it. While it appears…
Controlling species densities in structurally perturbed intransitive cycles with higher-order interactions
Sourin Chatterjee, Sayantan Nag Chowdhury, Dibakar Ghosh +1
The persistence of biodiversity of species is a challenging proposition in ecological communities in the face of Darwinian selection. The present article investigates beyond the pa…
