Some Aspects of Hyperscaling Violating Geometries at Finite Radial Cutoff

School
PARTICLES AND ACCELERATORS

Abstract: In this talk, I will first briefly review the proposal that a Toverline{T} deformed CFT is dual to a gravity theory in an asymptotically AdS spacetime at finite radial cutoff. Next, I will review Hyperscaling Violating geometries at finite radial cutoff and zero temperature which might be dual to Toverline{T}-like deformed HV QFTs in which Lorentz and scaling symmetries are broken. At the end, I will present our results for some measures of quantum entanglement such as: holographic entanglement entropy (HEE), mutual information (HMI) and entanglement wedge cross section (EWCS) which are calculated for entangling regions in the shape ...

Large-scale biomembrane modeling: thermodynamics, kinetics, and membrane-mediated interactions

School
NANO SCIENCES

Biomembranes are two-dimensional assemblies of phospholipids that are only a few nanometres thick, but form micrometer-sized structures vital to cellular function. All-atom simulations of biologically relevant membrane systems are computationally expensive, especially when the large number of solvent particles and slow membrane kinetics are taken into account. This necessitates the development of coarse-grained models for different scales of interest. In this talk, I present an ultra-coarse-grained membrane model that mimics the thermodynamics and kinetics of bilayer systems at large-scale. I describe our method for coupling this model to sol ...

Properly Ergodic Structures

School
MATHEMATICS

One natural notion of "random (countably infinite) L-structure" is a probability measure on the space of L-structures with domain omega which is invariant and ergodic for the natural action of the symmetric group Sym(omega) on this space. We call such a measure an ergodic structure. The most famous example of an ergodic structure is the Erdos-Renyi random graph model on domain omega, which gives measure 1 to the isomorphism type of the Rado graph. Ergodic structures also arise naturally as limits of sequences of finite structures which are convergent in the appropriate sense, generalizing the graph limits of Lovasz and Szegedy. Some ergod ...
