Dynamics of Eletrons in Molecules (DynEMol)

Description: DinEMol is an atomistic simulation tool capable of describing the nonadiabatic excited-state molecular dynamics of molecules adsorbed on extended solid surfaces as well as charge transfer processes. It is a mixed self-consistent quantum-classical Ehrenfest method for nonadiabatic MD simulations. The quantum mechanical part is described by the extended Hückel formalism whereas the nuclei are treated by molecular mechanics; the coupling between quantum-classical degrees of freedom is achieved by nonadiabatic generalized Hellmann-Feynman forces that conserve the total (quantum-classical) energy.
This document describes the formalism and demonstrates some of the capabilities of the method by describing photoexcited interfacial electron transfer and the photoisomerization dynamics of molecules in gas phase.
One of the goals of this research is to apply the present method in the study of photochemical switches and active photosensitizers.

Researchers: Luis Guilherme de Carvalho Rego and Kahio Tiberio Mazon.

Hadronic Physics in Nuclear and Stellar Matters

Description: The complete study of the QCD phase diagram requires complex calculations involving numerical algorithms developed in lattice QCD (LQCD) or the use of effective models. The former are still restricted to regions of very low chemical potential and, therefore, the use of models has served as a valuable tool for the advancement of knowledge. Nuclear and hadronic models generally make use of relativity, thermodynamics, field theory, and experimental and observational results that serve as links in determining parameters. Research developed by this group covers several regions of the QCD phase diagram. One of its main applications involves nuclear astrophysics and a whole process related to the study of stellar evolution, which starts from the construction of appropriate state equations. These state equations are applied to the investigation of liquid-gas phase transitions in the region of nuclear density and heavy ion collisions.

Researchers: Debora Peres Menezes (líder) and Marcus Emmanuel Benghi Pinto.

Concentration Area: Nuclear and Hadronic Physics.


Nuclear and Hadronic Physics

Description: In the field of hadron physics, the introduction of subnucleonic degrees is necessary for the understanding of the nuclear structure and of the relativistic effects in the description of nuclear matter and stellar matter and in the properties of finite nuclei. The consistent study of state equations obtained from relativistic models has applications to liquid-gas phase transitions at low densities; in a possible mixed phase known as ‘pasta phase’, also at low densities; in the production of particles at high temperatures in heavy ion collisions; in addition to important applications in nuclear astrophysics. The research carried out by this group, which also includes the study of stellar matter and quarks under intense magnetic field, have had a very positive impact on the development of nuclear and hadronic physics in the southern region of Brazil, with the constant improvement of human resources at both the undergraduate and graduate levels.

Researchers: Sidney dos Santos Avancini (líder) and Celso de Camargo Barros Júnior.
