Effective temperature concept evaluated in an active colloid mixture.
Thermal energy agitates all matter, and its competition with ordering tendencies is a fundamental organizing principle in the physical world; this observation suggests that an effective temperature might emerge when external energy input enhances agitation. However, despite the repeated proposal of this concept based on kinetics for various nonequilibrium systems, the value of an effective temp...
متن کاملEffective temperature of active matter.
We follow the dynamics of an ensemble of interacting self-propelled motorized particles in contact with an equilibrated thermal bath. We find that the fluctuation-dissipation relation allows for the definition of an effective temperature that is compatible with the results obtained using a tracer particle as a thermometer. The effective temperature takes a value which is higher than the tempera...
متن کاملConcept mapping: an effective, active teaching-learning method.
Nurse educators, under pressure to prepare graduates who are able to think critically and solve problems in a variety of clinical practice settings, require active teaching strategies to promote meaningful learning, instead of relying on traditional methods that promote rote memorization. A review of the current state of the science with regard to concept mapping demonstrates that this teaching...
متن کاملAn experimental study of a model colloid-polymer mixture
We report an experimental study of the phase bebaviour of a model hard sphere colloid + non-adsorbing polymer mixture sterically stabilised PMMA (radius = 217 nm) and polystyrene (r~ = 12.8 nm ) in cis-decalin. It was found'that the main effect of adding polymer was to expand the fluid-crystal coexistence region of the colloidal suspension, which
متن کاملEffective temperature of active complex matter
We use molecular dynamics simulations to study the dynamics of an ensemble of interacting self-propelled semi-flexible polymers in contact with a thermal bath. Our intention is to model complex systems of biological interest. We find that an effective temperature allows one to rationalize the out of equilibrium dynamics of the system. This parameter is measured in several independent ways – fro...
