Topological entropy of stationary three-dimensional turbulence
Ankan Biswas, Amal Manoharan, Ashwin Joy
Topological entropy serves as a viable candidate for quantifying mixing and complexity of a highly chaotic system. Particularly in turbulence, this is determined as the exponential…

Interlayer Charge-Transfer Ferroelectric Fluctuations as a Pairing Mechanism in van der Waals Superconductors
Ankan Biswas, Jagannath Sutradhar, Sudip Kumar Saha +2
Signatures of unconventional superconductivity have been reported in a wide range of van der Waals (vdW) materials. However, their microscopic origin remains unclear due to competi…

Intertwined geometries in collective modes of two dimensional Dirac fermions
Ankan Biswas, Avraham Klein
It is well known that the time-dependent response of a correlated system can be inferred from its spectral correlation functions. As a textbook example, the zero sound collective m…
