Dielectric response with short-ranged electrostatics. [PDF]
Proc Natl Acad Sci U S A, 2020 Significance Much of a liquid’s ability to act as a solvent stems from its dielectric properties. The intermolecular forces between polar molecules can act over very long ranges, which complicates both theoretical descriptions and molecular simulations.

Nature of Dielectric Response of Phenyl Alcohols. [PDF]
J Phys Chem B, 2023 Phenyl alcohols (PhAs) are an interesting class of materials, for which the dielectric response reveals only the presence of single prominent Debye-like (D) relaxation, interpreted as a genuine structural (α) process. Herein, we have performed dielectric and mechanical measurements on a series of PhAs characterized by the varying length of the alkyl ...

Dielectric response as a novel marker for ablation lesion quality: Relation to conventional ablation parameters. [PDF]
J Arrhythm, 2023 Background The tissue response viewer (TRV) is a novel marker for ablation lesion quality that aims to classify lesions into transmural or nontransmural lesions (high or low dielectric response, HDR or LDR) using dielectric‐based tissue assessment.

DFT Computed Dielectric Response and THz Spectra of Organic Co-Crystals and Their Constituent Components. [PDF]
Molecules, 2019 Terahertz (THz) spectroscopy has been put forth as a non-contact, analytical probe to characterize the intermolecular interactions of biologically active molecules, specifically as a way to understand, better develop, and use active pharmaceutical ...

Electric Conductivity and Electrode Polarization as Markers of Phase Transitions
Crystals, 2022 Dielectric polarization and electric polarization of electrodes are the common features of polar materials. We described methods to analyze their contributions and showed that both dependencies on temperature of dielectric conductivity and electrode ...

Nonlocal Dielectric Response of Water in Nanoconfinement [PDF]
Physical Review Letters, 2021 Recent experiments reporting a very low dielectric permittivity for nanoconfined water have renewed the interest to the structure and dielectric properties of water in narrow gaps. Here, we describe such systems with a minimal Landau-Ginzburg field-theory composed of a nonlocal bulk-determined term and a local water-surface interaction term.

Raman Response of Quantum Critical Ferroelectric Pb-Doped SrTiO3
Crystals, 2021 A quantum paraelectric SrTiO3 is a material situated in close proximity to a quantum critical point (QCP) of ferroelectric transition in which the critical temperature to the ferroelectric state is suppressed down to 0 K.

Simulating Nanoscale Dielectric Response [PDF]
Physical Review Letters, 2006 We introduce a constrained energy functional to describe dielectric response. We demonstrate that the local functional is a generalization of the long ranged Marcus energy. Our re-formulation is used to implement a cluster Monte Carlo algorithm for the simulation of dielectric media.
