Environment assisted and environment hampered efficiency at maximum power in a molecular photo cell
Subhajit Sarkar, Yonatan Dubi
The molecular photo cell, i.e., a single molecule donor-acceptor complex, beside being technologically important, is a paradigmatic example of a many-body system operating in stron…

Defect production and quench dynamics in the three-dimensional Kitaev model
Subhajit Sarkar, Dibyendu Rana, Saptarshi Mandal
We study the quench dynamics of the three-dimensional Kitaev (spin) model under a linear drive using both exact numerical calculations and analytical "independent crossing approxim…

Fermi surface instabilities of symmetry-breaking and topological types on the surface of a three-dimensional topological insulator
Subhajit Sarkar
The emergence of the Pomeranchuk instability (PI) in a Helical Fermi liquid (HFL) residing on the surface of a three-dimensional topological insulator (3D TI) is addressed at the m…
