Renormalization Method and Mirror Symmetry
Symmetry, Integrability and Geometry: Methods and Applications, 2012 This is a brief summary of our works [arXiv:1112.4063, arXiv:1201.4501] on constructing higher genus B-model from perturbative quantization of BCOV theory. We analyze Givental's symplectic loop space formalism in the context of B-model geometry on Calabi-

Remark on the subtractive renormalization of quadratically divergent scalar mass [PDF]
Phys.Rev.D83:105012,2011, 2011 The quadratically divergent scalar mass is subtractively renormalized unlike other divergences which are multiplicatively renormalized. We re-examine some technical aspects of the subtractive renormalization, in particular, the mass independent renormalization of massive $\lambda\phi^{4}$ theory with higher derivative regularization. We then discuss an

Exact Renormalization Groups As a Form of Entropic Dynamics
Entropy, 2018 The Renormalization Group (RG) is a set of methods that have been instrumental in tackling problems involving an infinite number of degrees of freedom, such as, for example, in quantum field theory and critical phenomena.

Coarse Graining Spin Foam Quantum Gravity—A Review
Frontiers in Physics, 2020 In quantum gravity, we envision renormalization as the key tool for bridging the gap between microscopic models and observable scales. For spin foam quantum gravity, which is defined on a discretization akin to lattice gauge theories, the goal is to ...

Renormalization of mixing angles [PDF]
Journal of High Energy Physics, 2018 A bstractWe discuss the renormalization of mixing angles for theories with extended scalar sectors. Motivated by shortcomings of existing schemes for mixing angles, we review existing renormalization schemes and introduce new ones based on on-shell ...

A hint of renormalization [PDF]
American Journal of Physics, 2004 An elementary introduction to perturbative renormalization and renormalization group is presented. No prior knowledge of field theory is necessary because we do not refer to a particular physical theory. We are thus able to disentangle what is specific to field theory and what is intrinsic to renormalization.

High precision renormalization of the flavour non-singlet Noether currents in lattice QCD with Wilson quarks [PDF]
The European Physical Journal C, 2018 We determine the non-perturbatively renormalized axial current for $$\hbox {O}(a)$$O(a) improved lattice QCD with Wilson quarks. Our strategy is based on the chirally rotated Schrödinger functional and can be generalized to other finite (ratios of ...

Renormalization of the Sigma-Omega model within the framework of U(1) gauge symmetry
, 2004 It is shown that the Sigma-Omega model which is widely used in the study of nuclear relativistic many-body problem can exactly be treated as an Abelian massive gauge field theory. The quantization of this theory can perfectly be performed by means of the
