On Riemannian manifolds with positive weighted Ricci curvature of negative effective dimension

open access: yes, 2018
In this paper, we investigate complete Riemannian manifolds satisfying the lower weighted Ricci curvature bound $\mathrm{Ric}_{N} \geq K$ with $K>0$ for the negative effective dimension $N0$, as a counterpart to the classical Obata rigidity theorem.

On the superfield effective potential in three dimensions

open access: yesPhysics Letters B, 2009
We develop the superfield approach to the effective potential in three dimensions and calculate the one-loop and two-loop k hlerian effective potential in commutative and noncommutative cases.

Effect of stimulus dimension on perception and cognition

open access: yesActa Psychologica, 2021
Stimuli characteristics ha a decisive role in our perception and cognition. In the present study, we aimed to evaluate the effects of dimension of stimuli, two-dimensional (2D) versus three-dimensional (3D), on perception and working memory. In the first experiment, using the method of eye tracking, a higher blink rate, pupil size, and the number of ...

Lepton Masses from a TeV Scale in a 3-3-1 Model

open access: yes, 2001
In this work, using the fact that in 3-3-1 models the same leptonic bilinear contributes to the masses of both charged leptons and neutrinos, we develop an effective operator mechanism to generate mass for all leptons.

Highly anisotropic Bose-Einstein condensates: crossover to lower dimensionality

open access: yes, 2002
We develop a simple analytical model based on a variational method to explain the properties of trapped cylindrically symmetric Bose-Einstein condensates (BEC) of varying degrees of anisotropy well into regimes of effective one dimension (1D) and ...

Dimensional reduction in manifold-like causal sets

open access: yes, 2017
We investigate the behavior of small subsets of causal sets that approximate Minkowski space in three, four, and five dimensions, and show that their effective dimension decreases smoothly at small distances.

Vacuum Structure of de Sitter Space [PDF]

open access: yes, 2010
In the in-/out-state formalism we find the exact one-loop effective action of a massive scalar field in the global coordinates of de Sitter spaces, which is a gravity analog of the Heisenberg-Euler action in QED.
