Non-relativistic Casimir effect at finite temperature
S. C. Ulhoa, A. F. Santos, Faqir C. Khanna
The Galilean covariance, formulated in 5-dimensions space, describes the non-relativistic physics in a way similar to quantum field theory. Using a non-relativistic approach the St…
Dimensional Deception from Noncommutative Tori: An alternative to Horava-Lifschitz
Fedele Lizzi, Aleksandr Pinzul
We study the dimensional aspect of the geometry of quantum spaces. Introducing a physically motivated notion of the scaling dimension, we study in detail the model based on a fuzzy…
Localization in the Rindler Wedge
M. Asorey, A. P. Balachandran, G. Marmo +1
One of the striking features of QED is that charged particles create a coherent cloud of photons. The resultant coherent state vectors of photons generate a non-trivial representat…
Non-commutative duality: the case of massless scalar fields
A. Pinzul, A. Stern
We show how to construct correlators for the which is dual to non-commutative (). We do it explicitly for the example of the massless scalar field on Eucli…
Equations of Motion as Covariant Gauss Law: The Maxwell-Chern-Simons Case
A. P. Balachandran, Arshad Momen, Amilcar R. de Queiroz
Time-independent gauge transformations are implemented in the canonical formalism by the Gauss law which is not covariant. The covariant form of Gauss law is conceptually important…
Renormalization group in super-renormalizable quantum gravity
Leonardo Modesto, Leslaw Rachwal, Ilya L. Shapiro
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 calcu…
