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…
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…
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…
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…
