Regularization of the Covariant Derivative on Curved Space by Finite Matrices
No full textIn a previous paper [M. Hanada, H. Kawai and Y. Kimura, Prog. Theor. Phys. 114 (2005), 1295] it is shown that a covariant derivative on any n-dimensional Riemannian manifold can be expressed in terms of a set of n matrices, and a new interpretation of IIB matrix model, in which the diffeomorphism, the local Lorentz symmetry and their higher spin analogues are embedded in the unitary symmetry, is proposed. In this article we investigate several coset manifolds in this formulation and show that on these backgrounds, it is possible to carry out calculations at the level of finite matrices by using the properties of the Lie algebras. We show how the local fields and the symmetries are embedded as components of matrices and how to extract the physical degrees of freedom satisfying the constraint proposed in the previous paper
Quantum chaos, thermalization, and entanglement generation in real-time simulations of the Banks-Fischler-Shenker-Susskind matrix model
No full textWe study numerically the onset of chaos and thermalization in the Banks-Fischler-Shenker-Susskind (BFSS) matrix model with and without fermions, considering Lyapunov exponents, entanglement generation, and quasinormal ringing. We approximate the real-time dynamics in terms of the most general Gaussian density matrices with parameters which obey self-consistent equations of motion, thus extending the applicability of real-time simulations beyond the classical limit. Initial values of these Gaussian density matrices are optimized to be as close as possible to the thermal equilibrium state of the system. Thus attempting to bridge between the low-energy regime with a calculable holographic description and the classical regime at high energies, we find that quantum corrections to classical dynamics tend to decrease the Lyapunov exponents, which is essential for consistency with the Maldacena-Shenker-Stanford bound at low temperatures. The entanglement entropy is found to exhibit an expected "scrambling" behavior - rapid initial growth followed by saturation. At least at high temperatures the entanglement saturation time appears to be governed by classical Lyapunov exponents. Decay of quasinormal modes is found to be characterized by the shortest timescale of all. We also find that while the bosonic matrix model becomes nonchaotic in the low-temperature regime, for the full BFSS model with fermions the leading Lyapunov exponent, entanglement saturation time, and decay rate of quasinormal modes all remain finite and nonzero down to the lowest temperatures.</p
Anatomy of deconfinement
No full textIn the weak coupling limit of SUN Yang-Mills theory and the O(N) vector model, explicit state counting allows us to demonstrate the existence of a partially deconfined phase: M of N colors deconfine, and MN gradually grows from zero (confinement) to one (complete deconfinement). We point out that the mechanism admits a simple interpretation in the form of spontaneous breaking of gauge symmetry. In terms of the dual gravity theory, such breaking occurs during the formation of a black hole. We speculate whether the breaking and restoration of gauge symmetry can serve as an alternative definition of the deconfinement transition in theories without center symmetry, such as QCD. We also discuss the role of the color degrees of freedom in the emergence of the bulk geometry in holographic duality.</p

a intelig^encia das nossas casas.
O f orum UPnP e uma iniciativa industrial criada para permitir a conectividade
f acil e robusta entre dispositivos auto-su cientes e PC's de diferentes
fabricantes. O objectivo deste f orum e desenvolver normas para descrever os
protocolos de comunica c~ao entre dispositivos e esquemas XML, e permitir
a opera c~ao entre dispositivos numa rede escal avel.
O DLNA foi criado em Junho de 2003 com o nome Digital Home Working
Group (DHWG), em Junho de 2004 foi alterado para Digital Living Network
Alliance (DLNA). A alian ca DLNA e liderada por 23 companhias (Access,
Awox, Broadcom, Cisco, Comcast, HP, Huawei, IBM, Intel, Kenwood, LG
Electronics, Macrovision, Microsoft, Motorola, Nokia, NXP Semiconductors,
Panasonic, Philips, Pioneer, Samsung, Sharp, Sony e Toshiba) e tem
mais de 245 membros.
Hoje em dia os consumidores est~ao a adquirir, ver e gerir uma grande quantidade

Uma rede DLNA oferece aos consumidores inter-conectividade autom atica
entre equipamentos dom esticos, e aos fabricantes uma oportunidade de
inovar e de diferenciar os seus produtos. Do ponto de vista do operador,
aumenta a capacidade de diagn ostico e gest~ao remota da rede de cliente.The world we live on is becoming more and more digital, our homes are
growing in intelligence. Standards like DLNA and UPnP AV propose to
exchange our digital media (photos, audio, video) in an automatic way.
The UPnP forum is a industrial initiative created to allow easy connectivity
and robustness between independent devices from di erent fabricators. The
objective of this forum is to develop templates to discriminate the protocols
and XML schemes involved in the process of interoperability in a scalable
network.

part of the home to their information present in other devices. This idea is
possible through a creation of a network with DLNA certi cated devices.
A DLNA network o ers automatic inter-connectivity between devices to the
consumers. It is an opportunity to innovate an di erentiate the products of
their fabricators. From the operator point of view, increases the diagnose

Phasing Delta-V for transfers from Sun–Earth halo orbits to the Moon
No full textInspired by successful extended missions such as the ISEE-3, an investigation for the extended mission that involves a lunar encounter following a Sun-Earth halo orbit mission is considered valuable. Most previous studies present the orbit-to-orbit transfers where the lunar phase is not considered. Intended for extended missions, the present work aims to solve for the minimum phasing ∆V for various initial lunar phases. Due to the solution multiplicity of the two-point boundary value problem, the general constrained optimization algorithm that does not identify multiple feasible solutions is shown to miss minima. A two-step differential corrector with a two-body Lambert solver is developed for identifying multiple solutions. The minimum ∆V associated with the short-way and long-way approaches can be recovered. It is acquired that the required ∆V to cover all initial lunar phases is around 45 m/s for the halo orbit with out-of-plane amplitude Az greater than 3.5×105 km, and 14 m/s for a small halo orbit with Az=1×105 km. In addition, the paper discusses the phasing planning based on the ∆V result and the shift of lunar phase with halo orbit revolution.</p

What lattice theorists can do for superstring/M-theory
No full textThe gauge/gravity duality provides us with nonperturbative formulation of superstring/M-theory. Although inputs from gauge theory side are crucial for answering many deep questions associated with quantum gravitational aspects of superstring/M-theory, many of the important problems have evaded analytic approaches. For them, lattice gauge theory is the only hope at this moment. In this review I give a list of such problems, putting emphasis on problems within reach in a five-year span, including both Euclidean and real-time simulations
