On the computational complexity of ising spin glass models
(1982)
In a spin glass with Ising spins, the problems of computing the magnetic partition function and finding a ground state are studied. In a finite two-dimensional lattice these problems can be solved by algorithms that require ...
Development of a dynamic framework to explain population patterns of leisure-time physical activity through agent-based modeling
(BioMed Central, 2017)
Abstract
Despite the increasing body of evidences on the factors influencing leisure-time physical activity, our understanding of the mechanisms and interactions that lead to the formation and evolution of ...
A correlation‐energy functional from a correlation‐factor model
(1994)
In this work, a way to approximate the correlation energy functional starting from a model correlation factor is shown. The problem is addressed by using formally exact properties of the second‐order density matrix and ...
Numerical analysis of Dicke’s model for one atom
(1982)
Using the Green function technique, the authors calculate the transition probability amplitude for one atom interacting with a one-mode electromagnetic field, without assuming the rotating-wave approximation (RWA). The ...
Prediction of h -> gamma Z from h -> gamma gamma at the LHC for the IMDS3 model
(Iop Publishing Ltd, 2015-11-01)
We consider the decays h -> gamma gamma, gamma Z in the context of an extension of the Standard Model with two inert doublets and an additional S-3 symmetry. This model contributes to for these processes through new charged ...
Physics beyond the standard model
(2016-01-01)
In these three lectures I review the need to go beyond the Standard Glashow-Weinberg-Salam Model and discuss some of the approaches that are explored in this direction.
Physical and numerical modelling of the thermally induced wedging mechanism
(ICE Publishing, 2015)
Field observations and laboratory experiments show that temperature cycles can lead to wedging
and accumulation of permanent displacements in several geosystems. The magnitude of these
displacements depends on the geometric ...
