Field theory model of brain extracellular matrix

Field theory model of brain extracellular matrix

The perineural net (PNN) is responsible for synaptic stabilization of adult brain. It plays an important role in brain signal processing and non-synaptic signal transfer as well [1]. Since it is composed of largely negatively charged chains of disaccharides, it can be easily affected by strong external electromagnetic field irradiated by high-energy particles passing brain tissues. One of the e...

Matrix model and string field theory

In this short note we would like to show the relation between the cubic open string field theory for N D-instantons and the string field theory in the presence of the background B field.

Matrix Model from String Field Theory

We show that the boundary string field theory (BSFT) on unstable D0-branes in 2d string theory is equivalent to the double scaled c = 1 matrix model (i.e. quadratic action), even though we naively expect many interaction terms in BSFT. It is checked that S-matrices are trivial in the open string theory on the D0-branes. We discuss how to take the closed string decoupling limit in our model in o...

0 Field Theory as a Matrix Model

A new formulation of four dimensional quantum field theories, such as scalar field theory, is proposed as a large n limit of a special n × n matrix model. Our reduction scheme works beyond planar approximation and applies for QFT with finite number of fields. It uses quenched coordinates instead of quenched momenta of the old Eguchi-Kawai reduction known to yield correctly only the planar secto...
