Abstract

The Bose-Einstein condensation (BEC) of the two-dimensional (2D) magnetoexcitonpolaritons in microcavity, where the Landau quantization of the electron and hole states accompanied by the Rashba spinorbit coupling plays the main role, was investigated. The Landau quantization levels of the 2D heavy holes with nonparabolic dispersion law and third-order chirality terms both induced by the external electric field perpendicular to the semiconductor quantum well and strong magnetic field B give rise to a nonmonotonous dependence of the magnetoexciton energy levels and the polariton energy branches on B.

18. The nambu-goldstone modes of bose-einstein condensed two-dimensional magnetoexcitons

Abstract

The collective elementary excitations of the two-dimensional (2D) electron-hole systems in a strong perpendicular magnetic field are discussed from the point of view of the Bogoliubov [1]and Goldstone [2] theorems concerning the many-body Hamiltonian with continuous symmetries,continuously degenerate ground states, forming a ring of minima on the energy scale in dependence on the phase of the field operator. This system due to the quantum fluctuations does select a concrete ground state with a fixed phase of the field operator forming a ground state with a spontaneously broken continuous symmetry [1-3]. The collective excitation of this new ground state related only with the changes of the field operator phase without changing its amplitude leads to the quantum transitions along the ring of the minima and does not need excitation energy in the long wavelength limit. This type of gapless excitations is referred to as Nambu-Goldstone modes [2-8]. They are equivalent to massless particles in the relativistic physics. The concrete realization of these theorems in the case of 2D magnetoexcitons with direct implications of the plasmon-type excitations side by side with the exciton ones is discussed below in terms of the Bogoliubov [1] theory of quasiaverages.

22. Delivery, consistency, and determinism: rethinking guarantees in distributed stream processing

Abstract

Consistency requirements for state-of-the-art stream processing systems are defined in terms of delivery guarantees. Exactly-once is the strongest one and the most desirable for end-user. However, there are several issues regarding this concept. Commonly used techniques that enforce exactly-once produce significant performance overhead. Besides, the notion of exactly-once is not formally defined and does not capture all properties that provide stream processing systems supporting this guarantee. In this paper, we introduce a formal framework that allows us to define streaming guarantees more regularly. We demonstrate that the properties of delivery, consistency, and determinism are tightly connected within distributed stream processing. We also show that having lightweight determinism, it is possible to provide exactly-once with almost no performance overhead. Experiments show that the proposed approach can significantly outperform alternative industrial solutions.

45. Reflectors and globalizations of partial actions of groups

Author

Subjects

Abstract

Given a partial action $\theta$ of a group on a set with an algebraic structure, we construct a reflector of $\theta$ in the corresponding subcategory of global actions and study the question when this reflector is a globalization. In particular, if $\theta$ is a partial action on an algebra from a variety ${\sf V}$, then we show that the problem reduces to the embeddability of certain generalized amalgam of ${\sf V}$-algebras associated with $\theta$. As an application, we describe globalizable partial actions on semigroups, whose domains are ideals., Comment: Minor changes
