183. Toolbox for HEP and sustainability of HEP event generators

Szabolcs Molnár (HUN-REN Wigner RCP)

29/05/2026, 10:50

Tuning a Monte Carlo Event Generator requires many tools and a lot of en-
ergy. For demonstrating what can be achieved with a toolbox—that contains all
of the required packages and dependencies to work out-of-the-box—HIJING++
is a perfect candidate for tuning. The tools—by default—can only be installed
separately and maintaining them one-by-one is a tedious task. The toolbox in
question...

198. Mixed Hamming-packings for benchmarking QUBO solvers

Péter Naszvadi (Wigner RCP)

29/05/2026, 11:10

In a recent work (Naszvadi, Adam and Koniorczyk, Mathematics 2025, 13(16), 2633) we have introduced an ILP model for solving the code-theoretic problem of finding the maximal cardinality of codes with a minimum codeword Hamming distance. Our method is not based on algebraic structure of the alphabets, it is suitable for decomposing bigger problem instances into equivalent smaller ones, and can...

206. Quantum Circuit and Tensor Network Simulation of the Acoustic Wave Equation

Prof. Gabor Vattay (Eötvös Loránd University)

29/05/2026, 11:30

Lecture

We present a cohesive framework for simulating seismic wave propagation utilizing quantum computing paradigms and their classical tensor network equivalents.
We detail a quantum circuit-based formulation for the explicit finite-difference time-domain (FDTD) solution of the two-dimensional acoustic wave equation and
map this quantum architecture onto a tensor train representation, namely...

195. Cognitive algebra: contexts, concepts and knowledge space

Antal Jakovac (Wigner RCP, Department of Computational Sciences)

29/05/2026, 11:50

Lecture

We introduce a minimal structural framework for cognitive representations based on the notion of context as a partition of the world state space. The framework treats invariance recognition and representative selection as fundamental operations and realizes them through a coupled Concept Graph and Procedure Graph. Together, these define a minimal cognitive algebra for constructing and...

192. Macroscopic quantum simulation of high-order harmonic generation in a gas jet, using upgraded 1d atomic model potentials

Attila Czirják (ELI-ALPS, and University of Szeged)

29/05/2026, 12:10

Lecture

We numerically investigate high-order harmonic generation (HHG) in a noble gas jet or cell with a supercomputer code [1] which computes the single atom response based on the one-dimensional (1D) time-dependent Schrödinger equation (TDSE) and couples it to the macroscopic propagation of the electromagnetic radiation, thus it enables to compare 1D TDSE-based HHG simulations with experimental...
