Functional renormalization group approach to zero-dimensional interacting systems [PDF]
J. Phys.: Condensed Matter 16, 5279 (2004), 2004 We apply the functional renormalization group method to the calculation of dynamical properties of zero-dimensional interacting quantum systems. As case studies we discuss the anharmonic oscillator and the single impurity Anderson model. We truncate the hierarchy of flow equations such that the results are at least correct up to second order ...

The renormalization group and the diffusion equation [PDF]
Progress of Theoretical and Experimental Physics, 2020 Abstract We study the relationship between the renormalization group and the diffusion equation. We consider the exact renormalization group equation for a scalar field that includes an arbitrary cutoff function and an arbitrary quadratic seed action.

Renormalization group theory of earthquakes [PDF]
Nonlinear Processes in Geophysics, 1996 We study theoretically the physical origin of the proposed discrete scale invariance of earthquake processes, at the origin of the universal log-periodic corrections to scaling, recently discovered in regional seismic activity ...

EXACT RENORMALIZATION GROUP FOR POINT INTERACTIONS
Acta Polytechnica, 2014 Renormalization is one of the deepest ideas in physics, yet its exact implementation in any interesting problem is usually very hard. In the present work, following the approach by Glazek and Maslowski in the flat space, we will study the exact ...

Ambipolar‐To‐Unipolar Conversion in Ultrathin 2D Semiconductors
Small Structures, Volume 3, Issue 12, December 2022., 2022 The applications of many 2D semiconductors have attracted considerable attention, but are severely limited by their ambipolar characteristics, which has sparked controversy about rethinking their potential. Thus, a comprehensive review is necessary for in‐depth understanding and to propose the optimum solutions for ambipolar treatment. Furthermore, the

Product Wave Function Renormalization Group Method [PDF]
, 1995 The authors propose a fast numerical renormalization group method --- the product wave function renormalization group (PWFRG) method --- for 1D quantum lattice models and 2D classical ones. A variational wave function, which is expressed by a matrix product, is improved through a self-consistent calculation.

Exact renormalization group in Batalin-Vilkovisky theory
Journal of High Energy Physics, 2018 In this paper, inspired by the Costello’s seminal work [11], we present a general formulation of exact renormalization group (RG) within the Batalin-Vilkovisky (BV) quantization scheme.

Stochastic renormalization group and gradient flow
Journal of High Energy Physics, 2020 A non-perturbative and continuous definition of RG transformations as stochastic processes is proposed, inspired by the observation that the functional RG equations for effective Boltzmann factors may be interpreted as Fokker-Planck equations. The result

2D Covalent Moiré Superlattice from Fluorinating Twisted Bilayer Graphene
Advanced Functional Materials, EarlyView.A novel class of moiré materials, termed covalent moiré superlattice is proposed, which can be synthesized by functionalizing moiré van der Waals materials. By fluorinating twisted bilayer graphene, the weak van der Waals interactions between twisted graphene layers are transformed into strong covalent bonds, making the moiré superlattice effects ...
