Statistical predictions from anarchic field theory landscapes

Statistical Predictions From Anarchic Field Theory Landscapes

Consistent coupling of effective field theories with a quantum theory of gravity appears to require bounds on the the rank of the gauge group and the amount of matter. We consider landscapes of field theories subject to such to boundedness constraints. We argue that appropriately “coarse-grained” aspects of the randomly chosen field theory in such landscapes, such as the fraction of gauge group...

Statistical Mechanics of Vortices from Field Theory

We study with lattice Monte Carlo simulations the interactions and macroscopic behaviour of a large number of vortices in the 3-dimensional U(1) gauge+Higgs field theory, in an external magnetic field. We determine non-perturbatively the (attractive or repelling) interaction energy between two or more vortices, as well as the critical field strength H c , the thermodynamical discontinuities, an...

Predictions for Orientifold Field Theories from Type 0’ String Theory

Two predictions about finite-N non-supersymmetric “orientifold field theories” are made by using the dual type 0’ string theory on C /Z2 × Z2 orbifold singularity. First, the mass ratio between the lowest pseudoscalar and scalar color-singlets is estimated to be equal to the ratio between the axial anomaly and the scale anomaly at strong coupling, M−/M+ ∼ C−/C+. Second, the ratio between the do...

Anarchic centromeres: deciphering order from apparent chaos☆

Specialised chromatin in which canonical histone H3 is replaced by CENP-A, an H3 related protein, is a signature of active centromeres and provides the foundation for kinetochore assembly. The location of centromeres is not fixed since centromeres can be inactivated and new centromeres can arise at novel locations independently of specific DNA sequence elements. Therefore, the establishment and...
