Regularization in quantum field theories

open access: yesVojnotehnički Glasnik, 2022
Introduction/purpose: The principal techniques of regularization schemes and their validity for gauge field theories are discussed. Methods: Schemes of dimensional regularization, Pauli–Villars and lattice regularization are discussed.

Dynamical renormalization of black-hole spacetimes [PDF]

open access: yesThe European Physical Journal C, 2019
We construct a black-hole spacetime which includes the running of the gravitational coupling in a self-consistent way. Starting from a classical Schwarzschild black hole, the backreaction effects produced by the running Newton’s coupling are taken into ...

Photo-Induced Bandgap Renormalization Governs the Ultrafast Response of Single-Layer MoS2. [PDF]

open access: yesACS Nano, 2016
Transition metal dichalcogenides (TMDs) are emerging as promising two-dimensional (2D) semiconductors for optoelectronic and flexible devices. However, a microscopic explanation of their photophysics, of pivotal importance for the understanding and ...

Renormalization of Hamiltonians [PDF]

open access: yesPhysical Review D, 1993
A matrix model of an asymptotically free theory with a bound state is solved using a perturbative similarity renormalization group for hamiltonians. An effective hamiltonian with a small width, calculated including the first three terms in the perturbative expansion, is projected on a small set of effective basis states. The resulting small hamiltonian

Phenomenological Renormalization Group Methods [PDF]

open access: yes, 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

Towards a Unitary, Renormalizable, and Ultraviolet-Complete Quantum Theory of Gravity

open access: yesFrontiers in Physics, 2020
For any fundamental quantum field theory, unitarity, renormalizability, and relativistic invariance are considered to be essential properties.

Neural Network Renormalization Group [PDF]

open access: yesPhysical 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
