Probing persistent spin textures through nonlinear magnetotransport
Neelanjan Chakraborti, Akash Dey, Snehasish Nandy +2
Persistent spin textures (PST) are special spin configurations in spin-orbit-coupled systems in which the spin polarization acquires a symmetry-enforced momentum-independent orient…

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…

Probing Fermi surface topology by ultrafast pump pulse dynamics
Debamalya Dutta, Kush Saha
We present a dynamical approach to detect changes in Fermi surface topology in a two-band model. Specifically, we show that the system's response to a low intensity light pulse can…
