Functional renormalization-group approach [PDF]
, 2018 We present a functional renormalization-group approach to interacting topological Green's function invariants with a focus on the nature of transitions. The method is applied to chiral symmetric fermion chains in the Mott limit that can be driven into a ...

Advanced Intelligent Discovery, EarlyView.This study introduces FIRE‐GNN, a force‐informed, relaxed equivariant graph neural network for predicting surface work functions and cleavage energies from slab structures. By incorporating surface‐normal symmetry breaking and machine learning interatomic potential‐derived force information, the approach achieves state‐of‐the‐art accuracy and enables ...

Symmetry properties, ward identities and renormalization group for Fermi and Bose systems
, 2001 Within the framework of the perturbative renormalization-group approach, we discuss the case when perturbation theory is affected by infrared divergences well inside a stable phase of matter.

Lung maneuvers of large amplitudes for probing physiological alterations in mouse models of asthma
Animal Models and Experimental Medicine, EarlyView.Lung maneuvers of small amplitudes, such as the ones performed in oscillometry, are the current gold standard to probe lung mechanics in animals, but they are insensitive to detect baseline physiological alterations in mouse models of asthma. Herein, lung maneuvers of different amplitudes were compared in two mouse models of asthma.

Low-energy theorem revisited and OPE in massless QCD
Journal of High Energy PhysicsWe revisit a low-energy theorem (LET) of NSVZ type in SU(N) QCD with N f massless quarks derived in [1] by implementing it in dimensional regularization. The LET relates n-point correlators in the l.h.s.

Renormalization group in super-renormalizable quantum gravity
European Physical Journal C: Particles and Fields, 2018 One of the main advantages of super-renormalizable higher derivative quantum gravity models is the possibility to derive exact beta functions, by making perturbative one-loop calculations.

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review
Advanced Physics Research, EarlyView.Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

Renormalization group procedure for potential −g/r2
Physics Letters B, 2018 Schrödinger equation with potential −g/r2 exhibits a limit cycle, described in the literature in a broad range of contexts using various regularizations of the singularity at r=0. Instead, we use the renormalization group transformation based on Gaussian
