Spin Chern phases and persistent spin texture in a quasi 2D SSH model
Hemant K Sharma, Saptarshi Mandal, Kush Saha
We construct a quasi-two-dimensional Su Schrieffer-Heeger model (SSH) like model and uncover a rich set of topological phases with nontrivial spin textures in the presence of compl…
Hat guessing with proper colorings
Sam Adriaensen, Peter Bentley, Anurag Bishnoi +6
We initiate the study of the hat guessing number of a graph where the adversary is only allowed to provide a proper coloring of the graph. This is the largest number for which…
Quantum Otto heat-engine with Kitaev-Heisenberg cluster: Possible roles of frustration, magnons, and duality
Sheikh Moonsun Pervez, Saptarshi Mandal
We study the performance of Kitaev-Heisenberg (KH) clusters as working media realizing a quantum Otto engine (QOE). An external Zeeman field with linear time dependency is used as…
