anchor.diff:  * \(f\) is the kick _frequency_, _T_ is the measured _temperature_
   * Kicks that are too frequent raise the temperature

  == Studying Active Matter
  
  * Active matter is an ongoing field of research
  
  * Much of it is concerned with studying bird flocks, fish schools, and bacterial swarms
  
  * Particles are usually *responsive* and *directed*
  
  [discrete]
  ==== *Active Matter* is composed of self-driven units, active particles, each capable of converting stored or ambient free energy into systematic movement [cite:marchetti_hydrodynamics_2013]
  
  == Janus Particles
  
  
negative.code: ** WCA potential / repulsive Lennard-Jones for \(U\)
  ** Damping \(\gamma\) to simulate solution viscosity
  ** Random, instantaneous "kicks" to the particles
  *** \(\vec \Gamma_T\) for the thermostat; balanced by \(\gamma\)
  *** \(\vec \Gamma_k\) for metabolism

  |============================
  | Thermostat | Metabolism

  * \(\Gamma_T \sim \Delta t k_B T \sim {10}^{-5} k_B T\)
  * Every timestep
  * Correlated: satisfy FDT
  * Gaussian distribution
  * Balanced by \(-\gamma \vec v\)
  |
  * \(0 \le E_k \le 20 k_B T\)
  * Instantaneous
  * Infrequent, ~100—1000 timesteps
  * Uncorrelated
  * Uniform distribution
