Importance of Varying Permittivity on the Conductivity of Polyelectrolyte Solutions [PDF]
Physical Review Letters 115, page 118301 (2015), 2015 Dissolved ions can alter the local permittivity of water, nevertheless most theories and simulations ignore this fact. We present a novel algorithm for treating spatial and temporal variations in the permittivity and use it to measure the equivalent conductivity of a salt-free polyelectrolyte solution.
