Neural Monte Carlo renormalization group

Physical Review Research, 2021
The key idea behind the renormalization group (RG) transformation is that properties of physical systems with very different microscopic makeups can be characterized by a few universal parameters.

Entanglement entropy: Holography and renormalization group [PDF]

Reviews of Modern Physics, 2018
In this review the entanglement and Renyi entropies in quantum field theory are described from different points of view, including the perturbative approach and holographic dualities.

Leading all-loop quantum contribution to the effective potential in general scalar field theory

Journal of High Energy Physics, 2023
The RG equation for the effective potential in the leading log (LL) approximation is constructed which is valid for an arbitrary scalar field theory in 4 dimensions.

Neural Network Renormalization Group [PDF]

Physical Review Letters, 2018
We present a variational renormalization group (RG) approach based on a reversible generative model with hierarchical architecture. The model performs hierarchical change-of-variables transformations from the physical space to a latent space with reduced

Analytically Solvable Renormalization Group for the Many-Body Localization Transition. [PDF]

Physical Review Letters, 2018
We introduce a simple, exactly solvable strong-randomness renormalization group (RG) model for the many-body localization (MBL) transition in one dimension.

Renormalization group and nonequilibrium action in stochastic field theory [PDF]

, 2002
We investigate the renormalization group approach to nonequilibrium field theory. We show that it is possible to derive nontrivial renormalization group flow from iterative coarse graining of a closed-time-path action.

Convergence of Nonperturbative Approximations to the Renormalization Group. [PDF]

Physical Review Letters, 2019
We provide analytical arguments showing that the "nonperturbative" approximation scheme to Wilson's renormalization group known as the derivative expansion has a finite radius of convergence. We also provide guidelines for choosing the regulator function

Phenomenological Renormalization Group Methods [PDF]

, 1999
Some renormalization group approaches have been proposed during the last few years which are close in spirit to the Nightingale phenomenological procedure. In essence, by exploiting the finite size scaling hypothesis, the approximate critical behavior of
