Two famous results of Einstein derived from the Jarzynski equality
Fred Gittes
The Jarzynski equality (JE) is a remarkable statement relating transient irreversible processes to infinite-time free energy differences. Although twenty years old, the JE remains…
Ion-sensitive phase transitions driven by Debye-Hückel non-ideality
Kyle J. Welch, Fred Gittes
We find that the Debye-Hückel nonideality of dilute aqueous electrolytes is sufficient to drive volume phase transitions and criticality, even in the absence of a self-attracting o…
Ionic phase transitions in non-ideal systems
Kyle J. Welch, Fred Gittes
We construct an explicitly solvable Landau mean-field theory for volume phase transitions of confined or fixed ions driven by relative concentrations of divalent and monovalent cou…
Determining Microscopic Viscoelasticity in Flexible and Semiflexible Polymer Networks from Thermal Fluctuations
B. Schnurr, F. Gittes, F. C. MacKintosh +1
We have developed a new technique to measure viscoelasticity in soft materials such as polymer solutions, by monitoring thermal fluctuations of embedded probe particles using laser…
Microscopic Viscoelasticity: Shear Moduli of Soft Materials Determined from Thermal Fluctuations
F. Gittes, B. Schnurr, P. D. Olmsted +2
We describe a high-resolution, high-bandwidth technique for determining the local viscoelasticity of soft materials such as polymer gels. Loss and storage shear moduli are determin…
