Bethe Ansatz for Quantum Strings

by Gleb Arutyunov, Sergey Frolov, Matthias Staudacher , 2004
"... We propose Bethe equations for the diagonalization of the Hamiltonian of quantum strings on AdS5×S 5 at large string tension and restricted to certain large charge states from a closed su(2) subsector. The ansatz differs from the recently proposed all-loop gauge theory asymptotic Bethe ansatz by add ..."

by additional factorized scattering terms for the local excitations. We also show that our ansatz quantitatively reproduces everything that is currently known about the string spectrum of these states. Firstly, by construction, we recover the integral Bethe equations describing semiclassical spinning strings

Higher-spin gauge interactions for massive matter fields

by S. F. Prokushkin, M. A. Vasiliev - in 3D AdS space-time,” Nucl. Phys. B 545 , 1999
"... A remarkable feature of the models with interactions exhibiting higher-spin (HS) gauge symmetries in d> 2 is that their most symmetric vacua require (anti)-de Sitter (AdS) geometry rather than the flat one. In striking parallelism to what might be expected of M theory HS gauge theories describe i ..."

-Simons) Yang-Mills interactions) of massive spin-0 and spin-1/2 matter fields in d = 2 + 1 AdS space-time. The parameter of mass of the matter fields is identified with the vev of a certain auxiliary field in the model. The matter fields are shown to be arranged into d3 N = 2 massive hypermultiplets in certain

Gauge Invariance and Phases of Massive Higher Spins in

by S. Deser, A. Waldron
"... The (m 2,Λ) plane of spin s> 1 massive fields in (A)dS backgrounds is shown to consist of separate phases, divided by lines of novel “partially massless ” gauge theories that successively remove helicities, starting from the lowest, 0 or ±1/2. The norms of the excluded states flip as the gauge li ..."

"... We treat free large N superconformal field theories as holographic duals of higher spin (HS) gauge theories expanded around AdS spacetime with radius R. The HS gauge theories contain massless and light massive AdS fields. The HS current correlators are written in a crossing symmetric form including ..."

Institutional transitions and strategic choices

by Mike W. Peng - Academy of Management Review
"... How do organizations make strategic choices during the time of fundamental institutional transitions such as those sweeping numerous emerging economies? To answer this question, a two-phase model of institutional transitions is developed in this article. I focus on the longitudinal process to move f ..."

; and delineate their performance implications. How do organizations make strategic choices during the time of fundamental and comprehensive institutional transitions? In three decades of research since the publication of Child's (1972) seminal paper, researchers have produced an impressive body of knowledge

Bulk Spin-Resonance Quantum Computation

by Neil A. Gershenfeld, Isaac L. Chuang - Computation,” Science , 1997
"... This article presents a new approach to quantum computing based on using bulk samples rather than isolated degrees of freedom. The problem, of course, is that such samples microscopically are in a thermal distribution of states, and it is impractical to hope to cool macroscopic materials to their gr ..."
Abstract - Cited by 118 (6 self) - Add to MetaCart
of this approach is that, because of the massive redundancy provided by having a large ensemble of identical copies of the system, environmental interactions or intentional measurements only weakly perturb the computer's state. Thus, quantum computation becomes experimentally accessible in many naturally

Gravito-electromagnetism versus electromagnetism

by A. Tartaglia, M. L. Ruggiero - Eur. J. Phys , 2004
"... The paper contains a discussion of the properties of the gravitomagnetic interaction in non stationary conditions. A direct deduction of the equivalent of Faraday-Henry law is given. A comparison is made between the gravito-magnetic and the electro-magnetic induction, and it is shown that there is n ..."

that there is no Meissner-like effect for superfluids in the field of massive spinning bodies. The impossibility of stationary motions in directions not along the lines of the gravito-magnetic field is found. Finally the results are discussed in relation with the behavior of superconductors. 1
