Nonperturbative infrared finiteness in super-renormalisable scalar quantum field theory

1 code implementation30 Sep 2020 Guido Cossu, Luigi Del Debbio, Andreas Juttner, Ben Kitching-Morley, Joseph K. L. Lee, Antonin Portelli, Henrique Bergallo Rocha, Kostas Skenderis

We present a study of the IR behaviour of a three-dimensional super-renormalisable quantum field theory (QFT) consisting of a scalar field in the adjoint of $SU(N)$ with a $\varphi^4$ interaction.

Machine learning determination of dynamical parameters: The Ising model case

1 code implementation26 Oct 2018 Guido Cossu, Luigi Del Debbio, Tommaso Giani, Ava Khamseh, Michael Wilson

We train a set of Restricted Boltzmann Machines (RBMs) on one- and two-dimensional Ising spin configurations at various values of temperature, generated using Monte Carlo simulations.

Accelerating HPC codes on Intel(R) Omni-Path Architecture networks: From particle physics to Machine Learning

no code implementations13 Nov 2017 Peter Boyle, Michael Chuvelev, Guido Cossu, Christopher Kelly, Christoph Lehner, Lawrence Meadows

This displays how a factor of ten speedup in strongly scaled distributed machine learning could be achieved when synchronous stochastic gradient descent is massively parallelised with a fixed mini-batch size.
