Exploring quantum quasi-crystal patterns: A variational approach

Prof. Dr. Alejandro Mendoza Coto

UFSC/FSC

Abstract:

In the present seminar I will discuss the emergence of quasicrystal configurations in the ground-state phase diagram of bosonic systems interacting through pair potentials of Lifshitz’s type. By using a variational mean-field approach, we determine the relevant features of the corresponding potential interaction kind stabilizing such quasicrystalline states in two dimensions. Unlike their classical counterpart, in which the interplay between only two wave vectors determines the resulting symmetries of the solutions, the quantum picture relates in a more complex way to the instabilities of the homogeneous phase. Moreover, the quantum quasicrystal patterns are found to emerge as the ground state with no need of moderate thermal fluctuations. The study extends to the exploration of the excitation properties and the possible existence of superquasicrystals, i.e., supersolidlike quasicrystalline states in which the long-range nonperiodic density profile coexists with a nonzero superfluid fraction. Our calculations suggest that, in an intermediate region between the homogeneous superfluid and the normal quasicrystal phases, these exotic states indeed exist at zero temperature. Comparison with full numerical simulations provides a solid verification of the variational approach adopted in this paper.

Enriquecimento químico de galáxias em grandes bases de dados

Profa. Dra. Natalia Vale Asari

UFSC/FSC

Abstract:

Oxigênio, nitrogênio, carbono. Ferro, níquel, molibdênio. A maioria dos elementos químicos mais pesados do que hidrogênio e hélio foram formados por nucleossíntese estelar. O ciclo de conversão do gás em estrelas e de estrelas em gás, portanto, regula o enriquecimento químico de uma galáxia. Bases de dados de milhões de espectros nos permitiram obter leis empíricas entre propriedades físicas de galáxias, como massa estelar, taxa de formação estelar e abundâncias químicas. Essas leis nos fornecem pistas sobre a interdependência entre a história de formação estelar e da evolução química de galáxias. Neste seminário, explicarei como os espectros de galáxias contém as impressões digitais da microfísica das nebulosas. Mostrarei também resultados de nossos trabalhos recentes com uma grande base de dados de espectroscopia integral. Darei destaque ao papel do gás difuso, e como ele pode enviesar a inferência de abundâncias químicas em galáxias.

Date: February 25, 2022 – (friday) – Time: 10:15 a.m.

Modelos microscópicos em econofísica para sociedades estratificadas a priori

Prof. Dr. Thiago Dias

UTFPR

Abstract:

Nesse trabalho são apresentados dois diferentes modelos para trocas de riqueza em uma sociedade composta por dois grupos distintos. No primeiro modelo as trocas acontecem em pares aleatoriamente escolhidos. Diferentes fatores de proteção sociais e número relativo de transações entre agentes dos diferentes grupos são considerados. O segundo modelo considera redes dinâmicas que podem ser alteradas a cada passo de tempo e as trocas econômicas acontecem entre os agentes vizinhos na rede. É investigado o papel da homofilia dos grupos nos indicadores econômicos e na rede.

Date: February 18, 2022 – (friday) – Time: 10:15 a.m.
