Exact Evaluation of Lattice-Regularized Scalar Field Vacuum Amplitude via Site Permutations
Vadim Asnin
A novel approach to a computation of vacuum amplitude for a single scalar field in any number of dimensions with arbitrary potential on a lattice is proposed. The computation invol…
Algorithm for multivariate data standardization up to third moment
Vadim Asnin
An algorithm for transforming multivariate data to a form with normalized first, second and third moments is presented.
On metric geometry of conformal moduli spaces of four-dimensional superconformal theories
Vadim Asnin
Conformal moduli spaces of four-dimensional superconformal theories obtained by deformations of a superpotential are considered. These spaces possess a natural metric (a Zamolodchi…
On evolutionary processes in large N quantum mechanics
Vadim Asnin
Equations of motion of large N quantum mechanics are solved for infinite N in the case of unbroken global O(N) symmetry. It is shown that the only correction to the action is a cha…
On rolling, tunneling and decaying in some large N vector models
Vadim Asnin, Eliezer Rabinovici, Michael Smolkin
Various aspects of time-dependent processes are studied within the large N approximation of O(N) vector models in three dimensions. These include the rolling of fields, the tunneli…
High and Low Dimensions in The Black Hole Negative Mode
Vadim Asnin, Dan Gorbonos, Shahar Hadar +3
The negative mode of the Schwarzschild black hole is central to Euclidean quantum gravity around hot flat space and for the Gregory-Laflamme black string instability. We analyze th…
