Large volumes and spectroscopy of walking theories
L. Del Debbio, B. Lucini, A. Patella +2
A detailed investigation of finite size effects is performed for SU(2) gauge theory with two fermions in the adjoint representation, which previous lattice studies have shown to be…
Renormalisation of the energy-momentum tensor in scalar field theory using the Wilson flow
Francesco Capponi, Luigi Del Debbio, Susanne Ehret +2
A non-perturbative renormalisation prescription for the energy-momentum tensor, based on space-time symmetries along the Wilson flow, has been proposed recently in the context of 4…
CP violation and Kaon weak matrix elements from Lattice QCD
Nicolas Garron
In this short review, I present the recent lattice computations of kaon weak matrix elements relevant to decays and neutral kaon mixing. These matrix elements are key to…
Implications of the absence of high-mass radion signals
Aqeel Ahmed, Barry M. Dillon, Bohdan Grzadkowski +2
Given the disappearance of the 750 GeV di-photon LHC signal and the absence of signals at high mass in this and other channels, significant constraints on the mixed Higgs-radion of…
Discrete triangulated categories
Nathan Broomhead, David Pauksztello, David Ploog
We introduce and study several homological notions which generalise the discrete derived categories of D. Vossieck. As an application, we show that Vossieck discrete algebras have…
A derivative-based approach for the leading order hadronic contribution to
Eric B. Gregory, Craig McNeile
We describe a lattice approach to calculating the leading-order hadronic contribution to the anomalous magnetic moment of the muon. We employ lattice momentum derivatives, in both…
Investigating some technical improvements to glueball calculations
Biagio Lucini, Craig McNeile, Antonio Rago
We briefly discuss some issues concerning including the pseudoscalar glueball interpolating operators into the variational basis for computing the masses of the eta and etaprime me…
The Low Energy Constants of Partially Quenched Chiral Perturbation Theory from Domain Wall QCD
P. A. Boyle, N. H. Christ, N. Garron +9
We have performed fits of the pseudoscalar masses and decay constants, from a variety of RBC-UKQCD domain wall fermion ensembles, to partially quenched chiral perturbation…
Turing Computation with Recurrent Artificial Neural Networks
Giovanni S Carmantini, Peter beim Graben, Mathieu Desroches +1
We improve the results by Siegelmann & Sontag (1995) by providing a novel and parsimonious constructive mapping between Turing Machines and Recurrent Artificial Neural Networks, ba…
renormalisation of four-quark operators
Julien Frison, Peter Boyle, Nicolas Garron
When several four-quark operators are allowed to mix through renormalisation, this can considerably amplify the problems coming from perturbative truncation and discretisation effe…
Measuring Vacuum Polarisation with High Power Lasers
B. King, T. Heinzl
When exposed to intense electromagnetic fields, the quantum vacuum is expected to exhibit properties of a polarisable medium akin to a weakly nonlinear dielectric material. Various…
An efficient algorithm for numerical computations of continuous densities of states
Kurt Langfeld, Biagio Lucini, Roberto Pellegrini +1
In Wang-Landau type algorithms, Monte-Carlo updates are performed with respect to the density of states, which is iteratively refined during simulations. The partition function and…
Lagrangian Constraints and Differential Thomas Decomposition
Vladimir P. Gerdt, Daniel Robertz
In this paper we show how to compute algorithmically the full set of algebraically independent constraints for singular mechanical and field-theoretical models with polynomial Lagr…
Charged hadrons in local finite-volume QED+QCD with C* boundary conditions
Biagio Lucini, Agostino Patella, Alberto Ramos +1
In order to calculate QED corrections to hadronic physical quantities by means of lattice simulations, a coherent description of electrically-charged states in finite volume is nee…
Non-perturbative tests of continuum HQET through small-volume two-flavour QCD
P. Fritzsch, N. Garron, J. Heitger
We study the heavy quark mass dependence of selected observables constructed from heavy-light meson correlation functions in small-volume two-flavour lattice QCD after taking the c…
Transport Conductivity of Graphene at RF and Microwave Frequencies
S. A. Awan, A. Lombardo, A. Colli +5
We measure graphene coplanar waveguides from direct current (DC) to 13.5GHz and show that the apparent resistance (in the presence of parasitic impedances) has an quadratic frequen…
Copula based generalized additive models with non-random sample selection
M. Wojtyś, G. Marra
Non-random sample selection is a commonplace amongst many empirical studies and it appears when an output variable of interest is available only for a restricted non-random sub-sam…
A cognitive neural architecture able to learn and communicate through natural language
Bruno Golosio, Angelo Cangelosi, Olesya Gamotina +1
Communicative interactions involve a kind of procedural knowledge that is used by the human brain for processing verbal and nonverbal inputs and for language production. Although c…
Fireflies: New software for interactively exploring dynamical systems using GPU computing
Robert Merrison-Hort
In non-linear systems, where explicit analytic solutions usually can't be found, visualisation is a powerful approach which can give insights into the dynamical behaviour of models…
Standard-model prediction for direct CP violation in decay
Z. Bai, T. Blum, P. A. Boyle +11
We report the first lattice QCD calculation of the complex kaon decay amplitude with physical kinematics, using a lattice volume and a single lattice spacing…
B-meson spectroscopy in HQET at order 1/m
Fabio Bernardoni, Benoît Blossier, John Bulava +7
We present a study of the B spectrum performed in the framework of Heavy Quark Effective Theory expanded to next-to-leading order in 1/m and non-perturbative in the strong coupling…
The density of states approach for the simulation of finite density quantum field theories
K. Langfeld, B. Lucini, A. Rago +2
Finite density quantum field theories have evaded first principle Monte-Carlo simulations due to the notorious sign-problem. The partition function of such theories appears as the…
Vacuum high harmonic generation in the shock regime
P. Böhl, B. King, H. Ruhl
Electrodynamics becomes nonlinear and permits the self-interaction of fields when the quantised nature of vacuum states is taken into account. The effect on a plane probe pulse pro…
