Nonlinear causality and stability of perfect spin hydrodynamics and its nonperturbative character
Samapan Bhadury, Zbigniew Drogosz, Wojciech Florkowski +2
Four formulations of perfect spin hydrodynamics for spin-1/2 particles, distinguished by their treatment of spin (classical vs. quantum) and by the underlying particle statistics (…
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…
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…
Spin hydrodynamics -- recent developments
Samapan Bhadury, Zbigniew Drogosz, Wojciech Florkowski +1
After briefly touching on relativistic hydrodynamics, we provide a detailed description of recent developments in spin hydrodynamics. We discuss the theory of perfect spin hydrodyn…
Application range of perfect spin hydrodynamics
Zbigniew Drogosz, Wojciech Florkowski, Valeriya Mykhaylova
The application range of perfect spin hydrodynamics is studied in two cases: one based on the classical spin description and the other using a quantum spin density matrix (Wigner f…
Local equilibrium Wigner function for spin-1/2 particles
Samapan Bhadury, Zbigniew Drogosz, Wojciech Florkowski +2
Formal connections between the spin density matrix and the Wigner function for spin-1/2 particles forming a relativistic gas are explored to determine their general structures. The…
Hybrid framework of Fermi-Dirac spin hydrodynamics
Zbigniew Drogosz
We outline the hybrid framework of spin hydrodynamics, combining classical kinetic theory with the Israel-Stewart method of introducing dissipation. We obtain the local equilibrium…
H and He nuclei production in a combined thermal and coalescence framework for heavy-ion collisions in the few-GeV energy regime
Zbigniew Drogosz, Wojciech Florkowski, Radoslaw Ryblewski +1
A thermal model describing hadron production in heavy-ion collisions in the few-GeV energy regime is combined with the idea of nucleon coalescence to make predictions for the H…
Using Space-Filling Curves and Fractals to Reveal Spatial and Temporal Patterns in Neuroimaging Data
Jacek Grela, Zbigniew Drogosz, Jakub Janarek +6
We present a novel method, Fractal Space-Curve Analysis (FSCA), which combines Space-Filling Curve (SFC) mapping for dimensionality reduction with fractal Detrended Fluctuation Ana…
