Critical curves in conformally invariant statistical systems
I. Rushkin, E. Bettelheim, I. A. Gruzberg +1
We consider critical curves -- conformally invariant curves that appear at critical points of two-dimensional statistical mechanical systems. We show how to describe these curves i…
Orthogonality catastrophe and shock waves in a non-equilibrium Fermi gas
E. Bettelheim, A. G. Abanov, P. Wiegmann
A semiclassical wave-packet propagating in a dissipationless Fermi gas inevitably enters a "gradient catastrophe" regime, where an initially smooth front develops large gradients a…
Quantum Shock Waves - the case for non-linear effects in dynamics of electronic liquids
Eldad Bettelheim, Alexander G. Abanov, Paul Wiegmann
Using the Calogero model as an example, we show that the transport in interacting non-dissipative electronic systems is essentially non-linear. Non-linear effects are due to the cu…
Bubble break-off in Hele-Shaw flows : Singularities and integrable structures
Seung-Yeop Lee, Eldad Bettelheim, Paul Wiegmann
Bubbles of inviscid fluid surrounded by a viscous fluid in a Hele-Shaw cell can merge and break-off. During the process of break-off, a thinning neck pinches off to a universal sel…
