Asymmetric Ions in Solution are Similar to Active Brownian Particles
Setare Mostajabi Sarhangi, Dmitry V. Matyushov
Molecular dynamics simulations of electrolyte ions with charge shifted by the distance from the ion geometrical center have shown that mechanical equilibrium in the ion's body…
Nonlinear dielectric relaxation of polar liquids
Tuhin Samanta, Dmitry V. Matyushov
Molecular dynamics of two water models, SPC/E and TIP3P, at a number of temperatures is used to test the Kivelson-Madden equation connecting single-particle and collective dielectr…
Screening of Coulomb interactions in liquid dielectrics
Salman Seyedi, Daniel R. Martin, Dmitry V. Matyushov
The interaction of charges in dielectric materials is screened by the dielectric constant of the bulk dielectric. In dielectric theories, screening is assigned to the surface charg…
Terahertz absorption of lysozyme in solution
Daniel R. Martin, Dmitry V. Matyushov
Absorption of radiation by solution is described by the solution dielectric constant and can be viewed as a specific application of the dielectric theory of solutions. For ideal so…

Salman Seyedi, Daniel R. Martin, Dmitry V. Matyushov
Mean square displacements of hydrogen atoms in glass-forming materials and proteins, as reported by incoherent elastic neutron scattering, show kinks in their temperature dependenc…
Dielectric constant of water in the interface
Mohammadhasan Dinpajooh, Dmitry V. Matyushov
We define the dielectric constant (susceptibility) that should enter the Maxwell boundary value problem when applied to microscopic dielectric interfaces. The dielectric constant (…
Mobility of nanometer-size solutes in water driven by electric field
Mohammadhasan Dinpajooh, Dmitry V. Matyushov
We investigate the mobility of nanometer-size solutes in water in a uniform external electric field. General arguments are presented to show that a closed surface cutting a volume…
Electrostatics of liquid interfaces
Dmitry V. Matyushov
The standard Maxwell formulation of the problem of polarized dielectrics suffers from a number of difficulties, both conceptual and practical. These difficulties are particularly s…
Depolarized light scattering and dielectric response of a peptide dissolved in water
Daniel R. Martin, Daniele Fioretto, Dmitry V. Matyushov
The density and orientational relaxation of bulk water can be separately studied by depolarized light scattering (DLS) and dielectric spectroscopy (DS), respectively. Here we ask t…
Electrophoretic mobility without charge driven by spontaneous polarization of the nanoparticle/water interface
Dmitry V. Matyushov
Polarization of the interface, spontaneously occurring when water is in contact with hydrophobic solutes or air, couples with the uniform external field to produce a non-zero force…
Electric field inside a "Rossky cavity" in uniformly polarized water
Daniel R. Martin, Allan D. Friesen, Dmitry V. Matyushov
Electric field produced inside a solute by a uniformly polarized liquid is strongly affected by dipolar polarization of the liquid at the interface. We show, by numerical simulatio…
Non-Gaussian statistics of electrostatic fluctuations of hydration shells
Allan D. Friesen, Dmitry V. Matyushov
We report the statistics of electric field fluctuations produced by SPC/E water inside a Kihara solute given as a hard-sphere core with a Lennard-Jones layer at its surface. The st…
Potential-tuning molecular dynamics studies of fusion, and the question of ideal glassformers: (I) The Gay-Berne model
Vitaliy Kapko, Dmitry V. Matyushov, C. Austen Angell
The ability of some liquids to vitrify during supercooling is usually seen as a consequence of the rates of crystal nucleation (and/or crystal growth) becoming small- thus a matter…
