Scaling regimes of the Kuramoto-Sivashinsky equation from the functional renormalization group
Liubov Gosteva, Nicolás Wschebor, Léonie Canet
We revisit the renormalization group (RG) approach to the one-dimensional stochastic Kuramoto-Sivashinsky (KS) equation and show that previous approaches based on perturbative Wils…
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…
Conformal Invariance of the large- limit of the universality class
Santiago Cabrera, Gonzalo De Polsi, Adam Rançon +1
Conformal symmetry is expected to be realized in many equilibrium statistical mechanical systems at criticality. Although this is certainly true in two-dimensional systems, the thr…
Unveiling the different scaling regimes of the one-dimensional Kardar-Parisi-Zhang--Burgers equation using the functional renormalisation group
Liubov Gosteva, Nicolás Wschebor, Léonie Canet
The Kardar-Parisi-Zhang (KPZ) equation is a celebrated non-linear stochastic equation featuring non-equilibrium scaling. Although in one dimension, its statistical properties are v…
Scenario for quark confinement from infrared safe Yang-Mills dynamics
Marcela Peláez, Urko Reinosa, Julien Serreau +2
We revisit the non-Abelian dipole problem in the context of a simple semiclassical approach that incorporates some essential features of the infrared sector of Yang-Mills theories…
Conformal invariance constraints in the models: a first study within the nonperturbative renormalization group
Santiago Cabrera, Gonzalo De Polsi, Nicolás Wschebor
The behavior of many critical phenomena at large distances is expected to be invariant under the full conformal group, rather than only isometries and scale transformations. When s…
