Second order gauge theory
(Elsevier B.V., 2007-05-01)
A gauge theory of second order in the derivatives of the auxiliary field is constructed following Utiyama's program. A novel field strength G = partial derivative F + fAF arises besides the one of the first order treatment, ...
Irreducibility and Computational Equivalence
(Springer, 2005)
We conduct a brief survey on Wolfram's classification, in particular related to the computing capabilities of Cellular Automata (CA) in Wolfram's classes III and IV. We formulate and shed light on the question of whether ...
Regularity of Mean-Field Games : an introduction
(2020-08-18)
Mean-field games, introduzido numa perspectiva de equações diferenciais parciais por Lions e Lasry, modelam situações com um grande número de agentes considerado um contínuo. O estudo da regularidade de funções é observar ...
Evolution of complexity following a quantum quench in free field theory
(2018-06-01)
Using a recent proposal of circuit complexity in quantum field theories introduced by Jefferson and Myers, we compute the time evolution of the complexity following a smooth mass quench characterized by a time scale δt in ...
Differential capacitance of an electrical double layer with asymmetric ion sizes in the presence of hydration interactions
(2019-10-20)
The differential capacitance is a fundamental property of an electrical double layer and thus important for the development of more efficient and environment-friendly energy storage devices. In addition to the bare ...
Rho-nucleon tensor coupling and charge-exchange resonances
(Elsevier B.V., 2000-11-23)
The Gamow-Teller resonance in Pb-208 is discussed in the context of a self-consistent RPA, based on the relativistic mean field theory. We inquire on the possibility of substituting the phenomenological Landau-Migdal force ...
