Standard Model Effective Field Theory and Oscillons
Z. Drogosz, E. I. Sfakianakis, K. Slawinska +1
We show that the inclusion of a dimension-six operator in the Higgs potential has a dramatic impact on the stability of oscillons in the bosonic sector of the Standard Mode…
Multifractal Signatures of Ageing and Dementia Development: A Multifractal Space-Filling Curve Analysis
Marta Lotka, Jacek Grela, Zbigniew Drogosz +2
Multifractality is an effective formalism for quantifying the nonlinear, scale-free properties of complex data. In this study, we propose a novel and efficient methodology, termed…
Machine learning in phase transition analysis of lattice quantum gravity
Jan Ambjorn, Zbigniew Drogosz, Jakub Gizbert-Studnicki +3
Using numerical data coming from Monte Carlo simulations of four-dimensional Causal Dynamical Triangulations, we study how automated machine learning algorithms can be used to reco…
Boost-invariant and cylindrically symmetric perfect spin hydrodynamics
Zbigniew Drogosz, Wojciech Florkowski, Jakub Witkowski
Equations of a boost-invariant and cylindrically symmetric perfect hydrodynamics are solved numerically for initial conditions inspired by the wounded nucleon model. The energy-mom…
Boost-invariant perfect Fermi-Dirac spin hydrodynamics
Zbigniew Drogosz, Natalia Åygan
We analyze the effect of using the Fermi-Dirac statistics, rather than its Boltzmann approximation, in numerical simulations of perfect spin hydrodynamics of particles with spin 1/…
Perfect spin hydrodynamics at all orders in spin polarization
Zbigniew Drogosz
We compare two recently developed frameworks of perfect spin hydrodynamics for spin- particles, based respectively on classical kinetic theory and the Wigner function. We show…
