Collective dynamics - Theoretical overview [PDF]
EPJ Web of ConferencesI overview the recent progress of phenomenological studies exploring collective dynamics in relativistic nuclear collisions to understand various QCD properties. Originally, collectivity was interpreted as a manifestation of the hydrodynamic behaviour of

Collective dynamics in optomechanical arrays [PDF]
Physical Review Letters, 2010 The emerging field of optomechanics seeks to explore the interaction between nanomechanics and light. Recently, the exciting concept of optomechanical crystals has been introduced, where defects in photonic crystal structures are used to generate both ...

Quantum Collective QCD String Dynamics [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2006 The string breaking model of particle production is extended in order to help explain the transverse momentum distribution in elementary collisions. Inspired by an idea of Bialas', we treat the string using a collective coordinate approach. This leads to

Collective dynamics from stochastic thermodynamics
New Journal of Physics, 2015 From a viewpoint of stochastic thermodynamics, we derive equations that describe the collective dynamics near the order-disorder transition in the globally coupled XY model and near the synchronization–desynchronization transition in the Kuramoto model ...

Collective Dynamics of Random Polyampholytes [PDF]
The Journal of Chemical Physics, 1998 We consider the Langevin dynamics of a semi-dilute system of chains which are random polyampholytes of average monomer charge $q$ and with a fluctuations in this charge of the size $Q^{-1}$ and with freely floating counter-ions in the surrounding.

Collective dynamics of sperm cells. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2020 While only a single sperm may fertilize the egg, getting to the egg can be facilitated, and possibly enhanced, by sperm group dynamics. Examples range from the trains formed by wood mouse sperm to the bundles exhibited by echidna sperm. In addition, observations of wave-like patterns exhibited by ram semen are used to score prospective sample fertility

Collective dynamics of kinesin [PDF]
Physical Review E, 2009 Motor proteins are biological enzymes that convert chemical energy to mechanical work in cells. Kinesin-1 is a motor protein that transports vesicles along microtubules and is widely believed to be responsible for anterograde transport of synaptic vesicles in neurons.

Biophysical basis for convergent evolution of two veil-forming microbes [PDF]
Royal Society Open Science, 2015 Microbes living in stagnant water typically rely on chemical diffusion to draw nutrients from their environment. The sulfur-oxidizing bacterium Thiovulum majus and the ciliate Uronemella have independently evolved the ability to form a ‘veil’, a ...

Quaternions in Collective Dynamics [PDF]
Multiscale Modeling & Simulation, 2018 We introduce a model of multi-agent dynamics for self-organised motion; individuals travel at a constant speed while trying to adopt the averaged body attitude of their neighbours. The body attitudes are represented through unitary quaternions. We prove the correspondance with the model presented in a previous work by the three first authors where the ...
