Probabilistic Time Series Forecasting with Implicit Quantile Networks
Adèle Gouttes, Kashif Rasul, Mateusz Koren +2
Here, we propose a general method for probabilistic time series forecasting. We combine an autoregressive recurrent neural network to model temporal dynamics with Implicit Quantile…
Extraction of bare Form Factors for Decays in non-perturbative HQET
Felix Bahr, Debasish Banerjee, Fabio Bernardoni +3
We discuss the extraction of the ground state matrix elements from Euclidean lattice correlation functions. The em…
The spectrum of 2+1 dimensional Yang-Mills theory on a twisted spatial torus
Margarita García Pérez, Antonio González-Arroyo, Mateusz Koren +1
We compute and analyse the low-lying spectrum of 2+1 dimensional Yang-Mills theory on a spatial torus of size with twisted boundary conditions. This paper exten…
HQET form factors for decays beyond leading order
Debasish Banerjee, Mateusz Koren, Hubert Simma +1
We compute semi-leptonic decay form factors using Heavy Quark Effective Theory on the lattice. To obtain good control of the expansion, one has to take into account n…
SU(3) Yang Mills theory at small distances and fine lattices
Nikolai Husung, Mateusz Koren, Philipp Krah +1
We investigate the SU(3) Yang Mills theory at small gradient flow time and at short distances. Lattice spacings down to fm are simulated with open boundary conditions to…
Extraction of the bare form factors for the semi-leptonic decays
F. Bahr, D. Banerjee, M. Koren +2
The computation of the form factors for the decay is presented. The b quark is treated by means of Heavy Quark Effective Theory, currently in the static approxim…

Felix Bahr, Debasish Banerjee, Fabio Bernardoni +4
We discuss the computation of form factors for semi-leptonic decays of -, - mesons in lattice QCD. Considering in particular the example of the static for…
Glueball masses in 2+1 dimensional SU(N) gauge theories with twisted boundary conditions
Margarita García Pérez, Antonio González-Arroyo, Mateusz Koren +1
We analyze 2+1 dimensional Yang-Mills theory regularized on a lattice with twisted boundary conditions in the spatial directions. In previous work it was shown that the observables…
Volume reduction in large-N lattice gauge theories [with adjoint fermions]
Mateusz Koren
This work covers volume reduction in quantum field theories on a lattice at large (number of colors), as first described by Eguchi and Kawai in 1982. The volume reduction (or v…
Screening in two-dimensional gauge theories
Piotr Korcyl, Mateusz Koren
We analyze the problem of screening in 1+1 dimensional gauge theories. Using QED2 as a warm-up for the non-abelian models we show the mechanism of the string breaking, in particula…
Large-N reduction with adjoint Wilson fermions
Barak Bringoltz, Mateusz Koren, Stephen R. Sharpe
We analyze the large-N behavior of SU(N) lattice gauge theories with adjoint fermions by studying volume-reduced models, as pioneered by Eguchi and Kawai. We perform simulations on…

Piotr Korcyl, Mateusz Koren, Jacek Wosiek
In this Letter we point out that the analytic solution of the two dimensional U(1) gauge theory, on a finite lattice, reveals in the continuum limit the renowned Manton's spectrum…

Piotr Korcyl, Mateusz Koren
Two-dimensional non-abelian quantum field models provide a useful laboratory for analytic and numerical investigations of quantum theories with gauge symmetry. They can exhibit var…

Barak Bringoltz, Mateusz Koren, Stephen R. Sharpe
We study the single site SU(N) lattice gauge theory with N_f=2 adjoint Wilson fermions for values of N up to 53. We determine the phase diagram of the theory as a function of the h…

Barak Bringoltz, Mateusz Koren, Stephen R. Sharpe
We use lattice simulations to study the single-site version of SU(N) lattice gauge theory with two flavors of Wilson-Dirac fermions in the adjoint representation, a theory whose la…
