A perturbative microscopic derivation of the focusing measure with rough cut-off
Shahnaz Farhat, Andrew Rout
We give a derivation of the Gibbs measure for the focusing nonlinear Schrödinger equation (NLS) on the circle with rough cut-off. This extends earlier work by Sohinger and the seco…

A microscopic derivation of Gibbs measures for the 1D focusing quintic nonlinear Schrödinger equation
Andrew Rout, Vedran Sohinger
In this work, we obtain a microscopic derivation of Gibbs measures for the focusing quintic nonlinear Schrödinger equation (NLS) on from many-body quantum Gibbs states…
