Modulation theory of quantum tunneling into a Calogero-Sutherland fluid

Research output: Contribution to journalArticlepeer-review

2 Scopus citations


Quantum hydrodynamics of interacting electrons with a parabolic single-particle spectrum is studied using the Calogero-Sutherland model. The effective action and modulation equations, describing the evolution of periodic excitations in the fluid, are derived. Applications to the problem of a single-electron tunneling into the FQHE edge state are discussed.
