A Quantization Procedure of Fields Based on Geometric Langlands Correspondence

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
We expose a new procedure of quantization of fields, based on the Geometric Langlands Correspondence. Starting from fields in the target space, we first reduce them to the case of fields on one-complex-variable target space, at the same time increasing ...

TOPOLOGY FIELDS, TOPOLOGICAL FLOWS AND TOPOLOGICAL ORGANISMS [PDF]

open access: yesJournal of the Chungcheong Mathematical Society, 2013
Topology may described a pattern of existence of elements of a given set X. The family of all topologies given on a set X form a complete lattice. We will give some topologies on this lattice using a topology on X and regard a topological space. A topology on X can be regarded a map from X to naturally.

What if the Universe Expands Linearly? A Local General Relativity to Solve the “Zero Active Mass” Problem

open access: yesThe Astrophysical Journal
Modern cosmology presents important challenges such as the Hubble Tension, El Gordo’s collision, or the impossible galaxies ( z > 10). Slight modifications to the standard model propose new parameters (e.g., the early and dynamical dark energy).

The Kibble-Zurek mechanism at exceptional points

open access: yesNature Communications, 2019
Universal non-equilibrium behaviour can emerge in physical systems when they are driven through a parameter regime where their energy gap closes. Dóra et al.

Imaging magnetic order in a two-dimensional iron-rich phyllosilicate

open access: yesCommunications Materials
Magnetic domain formation in two-dimensional materials offers insight into the fundamentals of magnetism and serves as a catalyst for the advancement of spintronics.

The chiral torsional anomaly and the Nieh-Yan invariant with and without boundaries

open access: yesJournal of High Energy Physics
There exists a long-standing debate regarding the torsion contribution to the 4d chiral anomaly of a Dirac fermion. Central to this debate is the Nieh-Yan anomaly, which has been considered ill-defined and a regularization artifact.

Geometry of branched minimal surfaces of finite index

open access: yesAdvanced Nonlinear Studies
Given I,B∈N∪{0} $I,B\in \mathbb{N}\cup \left\{0\right\}$ , we investigate the existence and geometry of complete finitely branched minimal surfaces M in R3 ${\mathbb{R}}^{3}$ with Morse index at most I and total branching order at most B. Previous works
