Equivariant Dimensional Reduction and Quiver Gauge Theories [PDF]

, 2010
We review recent applications of equivariant dimensional reduction techniques to the construction of Yang-Mills-Higgs-Dirac theories with dynamical mass generation and exactly massless chiral fermions.Comment: 10 pages; Based on invited talk given by the

Feature Selection Using Nearest Neighbor Gaussian Processes

Mathematics
We introduce a novel Bayesian approach for feature (variable) selection using Gaussian process regression, which is crucial for enhancing interpretability and model regularization.

Quantization as a dimensional reduction phenomenon

, 2006
Classical mechanics, in the operatorial formulation of Koopman and von Neumann, can be written also in a functional form. In this form two Grassmann partners of time make their natural appearance extending in this manner time to a three dimensional ...

Dimensional reduction and (Anti) de Sitter bounds

Journal of High Energy Physics, 2021
Dimensional reduction has proven to be a surprisingly powerful tool for delineating the boundary between the string landscape and the swampland. Bounds from the Weak Gravity Conjecture and the Repulsive Force Conjecture, for instance, are exactly ...

Dimensional Reduction and Quantum-to-Classical Reduction at High Temperatures

, 1995
We discuss the relation between dimensional reduction in quantum field theories at finite temperature and a familiar quantum mechanical phenomenon that quantum effects become negligible at high temperatures.

Dimensional reduction of the generalized DBI

Nuclear Physics B, 2015
We study the generalized Dirac–Born–Infeld (DBI) action, which describes a q-brane ending on a p-brane with a (q+1)-form background. This action has the equivalent descriptions in commutative and non-commutative settings, which can be shown from the ...

Dimensional reduction in quantum optics

Physical Review Research
One-dimensional quantum optical models usually rest on the intuition of large-scale separation or frozen dynamics associated with the different spatial dimensions, for example when studying quasi one-dimensional atomic dynamics, potentially resulting in ...

Two-color QCD via dimensional reduction

, 2012
We study the thermodynamics of two-color QCD at high temperature and/or density using a dimensionally reduced superrenormalizable effective theory, formulated in terms of a coarse grained Wilson line.

Dimensional reduction in causal set gravity

, 2015
Results from a number of different approaches to quantum gravity suggest that the effective dimension of spacetime may drop to $d=2$ at small scales. I show that two different dimensional estimators in causal set theory display the same behavior, and ...
