Inviscid scaling in the Kuramoto-Sivashinsky equation from functional renormalization group and direct numerical simulations
Liubov Gosteva, Dipankar Roy, Nicolás Wschebor +1
We show that the one-dimensional Kuramoto-Sivashinsky (KS) equation features a scaling regime characterized by the dynamical exponent at intermediate scales between the large…
Fixed Points and Universality Classes in Coupled Kardar-Parisi-Zhang Equations
Dipankar Roy, Abhishek Dhar, Manas Kulkarni +1
We study coupled KPZ equations with three control parameters . These equations are used in the context of stretched polymers in a random medium, for the spacetime spin-spin…
Large-scale multifractality and lack of self-similar decay for Burgers and 3D Navier-Stokes turbulence
Takeshi Matsumoto, Dipankar Roy, Konstantin Khanin +2
We study decaying turbulence in the 1D Burgers equation (Burgulence) and 3D Navier-Stokes (NS) turbulence. We first investigate the decay in time of the energy in Burgul…
Universality in coupled stochastic Burgers systems with degenerate flux Jacobian
Dipankar Roy, Abhishek Dhar, Konstantin Khanin +2
In our contribution we study stochastic models in one space dimension with two conservation laws. One model is the coupled continuum stochastic Burgers equation, for which each cur…
