Exact QFT duals of AdS black holes

open access: yesJournal of High Energy Physics, 2023
We construct large N saddle points of the matrix model for the N $$ \mathcal{N} $$ = 4 Yang- Mills index dual to the BPS black holes in AdS 5 × S 5, in two different setups.

Density of critical points for a Gaussian random function

open access: yes, 2007
Critical points of a scalar quantitiy are either extremal points or saddle points. The character of the critical points is determined by the sign distribution of the eigenvalues of the Hessian matrix.

Loop expansion around the Bethe-Peierls approximation for lattice models [PDF]

open access: yes, 2005
We develop an effective field theory for lattice models, in which the only non-vanishing diagrams exactly reproduce the topology of the lattice. The Bethe-Peierls approximation appears naturally as the saddle point approximation.

Covalent Organic Frameworks for Photocatalysis

open access: yesAdvanced Materials, EarlyView.
This review provides an overview of recent advances in covalent organic frameworks (COFs) for photocatalysis, focusing on sustainable energy applications like water splitting, hydrogen peroxide generation, and CO2 and N2 reduction. It discusses design principles, structure‐function relationships, challenges in COF photocatalysis, and strategies to ...

The Influence of Nonius Variety Amelioration with P.S.E. on Animals Productive Capacity

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
In the view of controlling the energetic capacity of the horse is necessary the constitutive elements measurement: force, speed and resistance. In the state studs starting with year 1920 were been applied different tests named qualification tests.

Role of saddles in mean-field dynamics above the glass transition

open access: yes, 2001
Recent numerical developments in the study of glassy systems have shown that it is possible to give a purely geometric interpretation of the dynamic glass transition by considering the properties of unstable saddle points of the energy.

Effect of second-rank random anisotropy on critical phenomena of random field O(N) spin model in the large N limit [PDF]

open access: yes, 2005
We study the critical behavior of a random field O($N$) spin model with a second-rank random anisotropy term in spatial dimensions ...

Labrador Sea freshening at 8.5 ka BP caused by Hudson Bay Ice Saddle collapse

open access: yesNature Communications, 2019
A significant reduction in the Atlantic Meridional Overturning Circulation and rapid northern Hemisphere cooling 8200 years ago have been linked to the final melting of the Laurentide Ice Sheet.
