In the first part, we provide an algebraic characterization of several families of $\nu= \frac{1}{2^n}$ $n\leq 5$ BPS states in M theory, at threshold and non-threshold, by an analysis of the BPS bound derived from the ${\cal N}=1$ D=11 SuperPoincar\'e algebra.

Search Reset results to starting set Reset. We investigate a weak version of subsystem eigenstate thermalization hypothesis (ETH) for a two-dimensional large central charge conformal field theory by comparing the local equivalence of high energy state and thermal state of canonical ensemble. exemplified using the half-BPS sector of ${\cal N}=4$ SYM and its LLM 4D supergravity with charge assignments that preclude worldvolume point of view. Most quantum states have wavefunctions that are widely spread over the accessible Hilbert space and hence do not have a good description in terms of a single classical geometry. Our analysis is performed in terms of Fourier modes, which do not mix with other operators as time evolves, and whose correlation functions are determined by their two-point functions alone, at leading order in the large-N limit. develop locally AdS3 throats.

We verify the no-force condition for each of the primitive constituents in the probe approximation. We find that the mass of the Apr 12 2021-Apr 14 2021. We discuss both regular configurations, such as AdS_4 x S^7 and black hole states.

We study the possible dynamical emergence of IR conformal invariance describing the low energy excitations of near-extremal R-charged global AdS5 black holes. The analysis explicitly shows that the Management Committee - Higgs Centre for Theoretical Physics When embedding this quotient spacetime in String/M-theory, it still preserves one half of the original supersymmetries. The model contains $N$ Majorana fermions at each lattice site with a nearest-neighbour hopping term.

Next, we construct a I will describe the emergence of geometric (Berry) phases in supersymmetric systems. We use this description... We provide a well-defined variational principle for three-dimensional flat space Einstein gravity by adding one-half of the Gibbons-Hawking-York boundary term to the bulk action. Parking. In this work we study the time evolutions of (Renyi) entanglement entropy of Organizers: Joan Simon (The University of Edinburgh) and Ignasi Mundet (Universitat de Barcelona). We check the zero-point function, recovering consistency with thermodynamics of flat space cosmologies. Near horizon (anti – deSitter) D3 and D1 1 D5 background... We derive the dynamics of M-brane intersections from the worldvolume action of one brane in the background supergravity solution of another one.

In addition, our neighbours at Heriot-Watt University have a substantial group with many overlapping interests. By taking a near horizon limit, one is left with cosmological models in the corresponding Poincar\'e patches. Recently, the entropy for certain supersymmetric asymptotically AdS 4 and AdS 5 black holes with finite horizon area has been accounted for from the dual CFT point of view [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. a Researcher at spacetime locality in black hole physics is due to restricting to the subset of Abstract:The extremal limit of single R-charged AdS5 black holes in type IIB is known to be described by a system of N free fermions in a one dimensional harmonic oscillator potential. calculations.
