Collective states of active matter with stochastic reversals: Emergent chiral states and spontaneous current switching

open access: yesPhysical Review Research, 2022
We study the collective dynamical behavior of active particles with topological interactions and directional reversals. Surprising phenomena are shown to emerge as the interaction relaxation time is varied relative to the reversal rate, such as the ...

Oscillations and collective behavior in convective flows [PDF]

open access: yesPhysics of Fluids, 2021
Oscillations and collective behavior in convection-driven fluid columns are investigated and discussed in analogy with similar phenomenon observed for the flickering flames of candle bundles. Experimentally, it is shown that an ascending circular helium gas column performs an oscillation which is similar in several aspects to the oscillation of ...

Collective flow and QCD phase transition [PDF]

open access: yes, 1999
In the first part I discuss the sensitivity of collective matter expansion in ultrarelativistic heavy-ion collisions to the transition between quark and hadronic matter (physics of the softest point of the Equation of State).

The High-Density Symmetry Energy in Heavy-Ion Collisions and Compact Stars

open access: yesUniverse, 2018
High-density nuclear symmetry energy is of crucial importance in astrophysics. Information on such energy has been obtained from mass–radius determinations of neutron stars (NSs), and in the future NS mergers will increasingly contribute.

Strange hadron collectivity in pPb and PbPb collisions

open access: yesJournal of High Energy Physics, 2023
The collective behavior of K S 0 $$ {\textrm{K}}_{\textrm{S}}^0 $$ and Λ / Λ ¯ $$ \Lambda /\overline{\Lambda} $$ strange hadrons is studied by measuring the elliptic azimuthal anisotropy (v 2) using the scalar-product and multiparticle correlation ...

Positive Emotions at Work and Job Crafting: Results From Two Prospective Studies

open access: yesFrontiers in Psychology, 2019
To date, research confirmed the effects of job crafting on the functioning of employees and organizations. In contrast, the evidence for the predictors of job crafting is limited.

Exact and Efficient Inference for Collective Flow Diffusion Model via Minimum Convex Cost Flow Algorithm

open access: yesAAAI Conference on Artificial Intelligence, 2020
Collective Flow Diffusion Model (CFDM) is a general framework to find the hidden movements underlying aggregated population data. The key procedure in CFDM analysis is MAP inference of hidden variables.

Collective dynamics of dense hairy surfaces in turbulent flow

open access: yesScientific Reports, 2023
Flexible filamentous beds interacting with a turbulent flow represent a fundamental setting for many environmental phenomena, e.g., aquatic canopies in marine current. Exploiting direct numerical simulations at high Reynolds number where the canopy stems

Direct Photon Production in Heavy-Ion Collisions: Theory and Experiment

open access: yesParticles, 2023
Direct photons provide a possibility to test properties of hot matter created in proton–proton (pp), proton–nucleus (p–A) or nucleus–nucleus (A–A) collisions.

Angle and magnitude decorrelation in the factorization breaking of collective flow [PDF]

open access: yesPhysical Review C, 2018
The collective harmonic flow in heavy-ion collisions correlates particles at all transverse momenta to be emitted preferably some directions. The factorization breaking coefficient measures the small decorrelation of the flow harmonics at two different ...
