Distributive and anti-distributive Mendelsohn triple systems
Diane M. Donovan, Terry S. Griggs, Thomas A. McCourt +2
We prove that the existence spectrum of Mendelsohn triple systems whose associated quasigroups satisfy distributivity corresponds to the Loeschian numbers, and provide some enumera…
Double Compton scattering in a constant crossed field
B. King
Two-photon emission of an electron in an electromagnetic plane wave of vanishing frequency is calculated. The unpolarised probability is split into a two-step process, which is sho…
Testing numerical implementations of strong field electrodynamics
C. N. Harvey, A. Ilderton, B. King
We test current numerical implementations of laser-matter interactions by comparison with exact analytical results. Focussing on photon emission processes, it is found that the num…
High-precision quark masses and QCD coupling from lattice QCD
Bipasha Chakraborty, C. T. H. Davies, G. C. Donald +6
We present a new lattice QCD analysis of heavy-quark pseudoscalar-pseudoscalar correlators, using gluon configurations from the MILC collaboration that include vacuum polarization…
Sideband Mixing in Intense Laser Backgrounds
Martin Lavelle, David McMullan
The electron propagator in a laser background has been shown to be made up of a series of sideband poles. In this paper we study this decomposition by analysing the impact of the r…
Optimal alignments of longest common subsequences and their path properties
Jüri Lember, Heinrich Matzinger, Anna Vollmer
We investigate the behavior of optimal alignment paths for homologous (related) and independent random sequences. An alignment between two finite sequences is optimal if it corresp…
Interaction of photons traversing a slowly varying electromagnetic background
B. King, P. Böhl, H. Ruhl
When two electromagnetic fields counterpropagate, they are modified due to mutual interaction via the polarised virtual electron-positron states of the vacuum. By studying how phot…
Photon polarisation in light-by-light scattering: finite size effects
Victor Dinu, Tom Heinzl, Anton Ilderton +2
We derive a simple expression for the photon helicity and polarisation-flip probabilities in arbitrary background fields, in the low energy regime. Taking the background to model a…
Default Probability Estimation via Pair Copula Constructions
Luciana Dalla Valle, Maria Elena De Giuli, Claudia Tarantola +1
In this paper we present a novel approach for firm default probability estimation. The methodology is based on multivariate contingent claim analysis and pair copula constructions.…
The density of states approach to dense quantum systems
Kurt Langfeld, Biagio Lucini
We develop a first-principle generalised density of state method for studying numerically quantum field theories with a complex action. As a proof of concept, we show that with our…
Critical exponents of the 3d Ising and related models from Conformal Bootstrap
Ferdinando Gliozzi, Antonio Rago
The constraints of conformal bootstrap are applied to investigate a set of conformal field theories in various dimensions. The prescriptions can be applied to both unitary and non…
Finding the effective Polyakov line action for SU(3) gauge theories at finite chemical potential
Jeff Greensite, Kurt Langfeld
Motivated by the sign problem, we calculate the effective Polyakov line action corresponding to certain SU(3) lattice gauge theories on a lattice via the "relativ…
Vacuum refractive indices and helicity flip in strong-field QED
Victor Dinu, Tom Heinzl, Anton Ilderton +2
Vacuum birefringence is governed by the amplitude for a photon to flip helicity or polarisation state in an external field. Here we calculate the flip and non-flip amplitudes in ar…
Recent progress in the effective string theory description of LGTs
Marco Billò, Michele Caselle, Davide Fioravanti +4
In presence of a static pair of sources, the spectrum of low-lying states of any confining gauge theory in D space-time dimensions is described, at large source separations, by an…
BSMBench: a flexible and scalable supercomputer benchmark from computational particle physics
Ed Bennett, Luigi Del Debbio, Kirk Jordan +4
Lattice Quantum ChromoDynamics (QCD), and by extension its parent field, Lattice Gauge Theory (LGT), make up a significant fraction of supercomputing cycles worldwide. As such, it…
