Pattern-formation and Critical Behaviour in Dipolar Bose-Einstein Condensates
Fabian Maucher

Department of Physics and Astronomy, Aarhus University, 8000 Aarhus C, Denmark

Abstract:

Fabian Maucher, Yong-Chang Zhang, and Thomas Pohl
Department of Physics and Astronomy, Aarhus University, 8000 Aarhus C, Denmark 
The formation of patterns with long-range order continues to fascinate scientists from a broad range of natural sciences [1]. In this talk I will discuss pattern-formation in dipolar Bose-Einstein condensates. In this system the possibility of obtaining quantum states with self-organized long-ranged ordering can be facilitated by quantum fluctuations which suppress collapse and pave the way for supersolids in this system [2]. Here, supersolidity refers to a state of matter which displays long-range ordering whilst maintaining a large superfluid fraction. I will present recent results which focus on the critical behaviour of the superfluid-supersolid phase-transition [3] and the crucial role quantum fluctuations can play for the latter. We find that quantum fluctuations can alter the order of the phase transition from first- to second order. Furthermore, apart from the usual triangular lattice of density droplets, quantum fluctuations can give rise to a novel quantum state whose density distribution displays a honeycomb structure.

A física nuclear como ferramenta para explicar magnetares e ondas gravitacionais

Profª. Drª. Débora Peres Menezes
UFSC/FSC

Abstract:

A neutron star was first detected as a pulsar in 1967. It is one of the most mysterious objects in the universe, with a radius of the order of 10 km and masses that can reach two solar masses. In 2017, a gravitational wave was detected (GW170817) and its source was identified as the merger of two neutron stars. The same event was seen in X-ray, gamma-ray, UV, IR, radio frequency and even in the optical region of the electromagnetic spectrum, starting the new era of multi-messenger astronomy. To understand neutron stars, an appropriate equation of state that satisfies bulk nuclear matter properties has to be used and GW170817 has provided some extra constraints to determine it.
On the other hand, some neutron stars have strong magnetic fields up to 10 to the 15 Gauss on the surface as compared with the usual 10 to the 12 Gauss normally present in ordinary pulsars. They are called magnetars. While the description of ordinary pulsars is not completely established, describing magnetars poses a real challenge because the magnetic fields can produce an anisotropic equation of state. It is also known that low magnetic fields do not affect the equation of state and the resulting star macroscopic properties but they do affect the crust-core transition and the crust thickness with many consequences, as the explanation of glitches and the calculation of the Love number and quadrupole tidal polarisabilities.I will talk about the importance of the new constraints imposed by GW170817 in the determination of appropriate equations of state, possible ways to describe hadronic and quark matter subject to strong magnetic fields and the problems that lie ahead in the understanding of magnetars.

O motor térmico quântico de Unruh-Otto

Prof. Enrique Arias
Universidade do Estado do Rio de Janeiro

Abstract:

Neste seminário apresentaremos um motor térmico quântico que aproveita as flutuações quânticas do vácuo para modelar um reservatório térmico. As propriedades térmicas do vácuo podem ser postas de manifesto quando um campo quântico é colocado nas vizinhanças de um buraco negro (efeito Hawking) ou se ele é analisado por um observador não-inercial com aceleração própria constante (efeito Unruh). Desta maneira um qubit acelerado em contato com o estado de vácuo de um campo quântico perceberá este estado como um banho térmico com temperatura proporcional à sua aceleração. Conseqüentemente, o qubit acelerado pode explorar as flutuações quânticas do vácuo (banho térmico) e extrair energia dele (calor) para realizar trabalho útil e assim definir um motor térmico. É importante notar que as noções de calor e trabalho que temos que usar para definir nosso motor térmico via o efeito Unruh não são as definições usuais e neste ponto temos que utilizar as prescrições da termodinâmica quântica. Neste seminário apresentaremos especificamente o motor térmico quântico de Otto via o efeito Unruh e analisaremos sua eficiência e as condições de periodicidade e positividade necessárias para seu funcionamento.

Quantum Uncloneability

Prof Anne Broadbent
University of Ottawa

Abstract:

The quantum “no-cloning” theorem is one of the simplest yet most profound results in quantum information. According to this theorem, it is not possible to perfectly copy an unknown quantum state. In this presentation, we will introduce the formalism that leads to quantum information and the no-cloning theorem and we will discuss some of the amazing consequences of this theorem, such as unforgeable quantum money and perfectly secure quantum communications.
