Fields of Research:

 

CLASSIC AREAS OF PHENOMENOLOGY AND THEIR APPLICATIONS

Description:
Study of mass, energy and moment transfer in complex systems, employing analytical and numerical modelling and simulation techniques

STELLAR ASTROPHYSICS

Description:
Stellar Astrophysics is the study of the physics of stars, their formation, their evolution, structure and, as well, their properties as mass, age and chemistry. This broad branch of science deals with a wide spectrum of areas of knowledge. In particular, in physics, it ranges from classical mechanics and electromagnetism to relativity and quantum mechanics, as well as nuclear physics and thermodynamics. The physics of stars can be determined through observation by telescopes, theory and computational simulation. Today, stellar astrophysics has had a profound growth in the field of asterosmology (study of the stellar interior) and in Exoplantology (science of the formation of extrasolar planets), areas which until the middle of the last decade were essentially theoretical and had only the solar system as reference.

CAOS

Description:
The emergence of chaos in classical and quantum systems is studied through the variation of one or more control parameters of the system under study. The causes that lead to chaotic behaviour as well as the characterisation of these states are also studied.

ATOMIC AND MOLECULAR PHYSICS

Description:
Study of the spectrum of complex atoms and molecules

BIOLOGICAL PHYSICS

Description:
Biological Physics is the field of knowledge in which the physical processes that govern living systems are studied. The study consists of the construction of models to study the complex network of interactions of living matter and to improve the potentials that determine the association and organization of microscopic structures into macro structures. The focus of this area is the study of systems at the molecular and cellular level using physical principles such as: statistical mechanics, continuum mechanics, nonlinear dynamics, nonlinear optics, colloid physics, among others. In addition, the study approach can be done both experimentally, such as through microscopy or spectroscopy measurements, and theoretically, such as through analytical or computational analysis.

CLASSICAL AND QUANTUM PHYSICS; MECHANICS AND FIELDS

Description:
Characterization of classical and quantum systems for studies of electronic and transport properties

STATISTICAL PHYSICS AND THERMODYNAMICS

Description:
Application of probabilistic methods used in statistical physics for the analysis of the behaviour of complex systems in equilibrium and out of equilibrium, including various types of applications

QUANTUM MECHANICS FUNDAMENTALS

Description:
The concept of non-commutative coordinates as a way of removing divergences in field theory by means of a universal invariant length parameter was proposed by Heisenberg. This idea has as consequence the quantization of space-time, where a noncommutative space operator is defined to allow the development of an invariant theory before a Lorentz transformation, but which is not invariant before translation. This last property makes the space-time coordinates continuous. Thus, the need for a universal scale length becomes evident in different areas of physics such as relativity, string theory, and quantum gravitation. In the particular case of quantum mechanics, this minimum scale length leads to a modification of the switching relation between position and momentum. In this way, we introduce a translation operator which depends on the position. Such an operator both modifies the switching relationship between x and p and can be used to explain problems which have position-dependent mass.

PREPARATION, CHARACTERIZATION AND APPLICATIONS OF (NANO)FUNCTIONAL MATERIALS

Description:
This line of research is focused on the preparation, characterization, functionalization and applications of (nano)carbonaceous materials (C-dots, hydrothermal coal, pyrolytic coal, nanostructured carbon and carbon-based nanocomposites) and inorganic materials (nanoparticles, nanotubes and inorganic (nano)clays). Both carbon-based and inorganic (nano)materials are prepared by chemical and/or physical routes within top-down and bottom-up strategies. For the preparation of (nano)carbonaceous materials, renewable precursor sources such as biomass, biomolecules extracted from biomass and/or agribusiness residues are used. Nanomaterials are characterised from the perspective of understanding their physical and chemical properties. In addition, nanomaterials are developed from the perspective of (multi)specific functionalities for environmental, (photo)catalytic, agricultural (black earth) and energy applications with a view to adding value and sustainable development.
