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…

The Smearing of Quasi-Particles: Signatures in the Entanglement Entropy of Excited Many-Particle Systems
Jagannath Sutradhar, Jonathan Ruhman, Avraham Klein +2
The entanglement spectrum serves as a powerful tool for probing the structure and dynamics of quantum many-body systems, revealing key information about symmetry, topology, and exc…
