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…
Kaganov-Lifshitz-Tanatarov theory for tilted Dirac-cone materials: anisotropic heating from uniform light
Navinder Singh Bathinda, Bharathiganesh Devanarayanan, Sruthi Sudhakaran +2
We point out that in the tilted Dirac cone materials the non-equilibrium (hot) electron relaxation with phonons is anisotropic in the Brillouin zone. It means that there is a prefe…
A primer on Kitaev Model: Basic aspects, material realization, and recent experiments
Saptarshi Mandal
This elementary review article is aimed to the beginning graduate students interested to know basic aspects of Kitaev model. We begin with a very lucid introduction of Kitaev model…
Extended Haldane model -- a modern gateway to topological insulators
Tanay Nag, Saptarshi Mandal
The seminal Haldane model brings up a paradigm beyond the quantum Hall effect to look for a plethora of topological phases in the honeycomb and other lattices. Here we dwell into t…
Deciphering competing interactions of Kitaev-Heisenberg- system in clusters: part II -- dynamics of Majorana fermions
Sheikh Moonsun Pervez, Saptarshi Mandal
We perform a systematic and exact study of Majorana fermion dynamics in the Kitaev-Heisenberg- model in a few finite-size clusters increasing in size up to twelve sites. We empl…
Emergent topological phases in an extended Su-Schrieffer-Heeger model with Rashba spin-orbit interaction, higher order hopping and domain wall
Hemant Kumar Sharma, Arijit Saha, Saptarshi Mandal
We theoretically investigate emergent topological phases in an extended spin-full Su-Schrieffer-Heeger (SSH) model considering Rashba spin-orbit interaction, all possible complex n…
