Unusual Yang-Lee edge singularity in the one-dimensional axial-next-to-nearest-neighbor Ising model
(Amer Physical Soc, 2010-11-05)
We show here for the one-dimensional spin-1/2 axial-next-to-nearest-neighbor Ising model in an external magnetic field that the linear density of Yang-Lee zeros may diverge with critical exponent sigma=-2/3 at the Yang-Lee ...

Path integral approach to the full Dicke model
(Elsevier B.V., 2011-10-01)
The full Dicke model describes a system of N identical two level-atoms coupled to a single mode quantized bosonic field. The model considers rotating and counter-rotating coupling terms between the atoms and the bosonic ...
Exact phase space functional for two-body systems
(2010-11-21)
The determination of the two-body density functional from its one-body density is achieved for Moshinsky's harmonium model, using a phase-space formulation, thereby resolving its phase dilemma. The corresponding sign rules ...
Study of a sequence to stimulate the engagement in one-to-one iPad programs at elementary schools
The number of one-to-one mobile programs in elementary schools as a resource to substitute the textbook has become popular worldwide. However, findings of studies that seek to enable understanding of how the daily use of ...
Laboratory Tests with Model Based on pi Circuits Considering the Introduction of Branches Composing by RL Parallel Elements
(Ieee, 2018-01-01)
For simple transmission line models, it can be applied pi circuit cascades. This type of circuits was applied for composing a physical model that has been applied for simulating of propagation of simple electromagnetic ...

Magnetic field evolution in neutron stars: one-dimensional multi-fluid model
(2008)
This paper is the first in a series aimed at understanding the long-term evolution of neutron star magnetic fields. We model the stellar matter as an electrically neutral and lightly ionized plasma composed of three moving ...
Ross-Macdonald models: Which one should we use?
(Elsevier Science, 2020-07)
Ross-Macdonald models are the building blocks of most vector-borne disease models. Even for the same disease, different authors use different model formulations, but a study of the dynamical consequences of assuming different ...
