The microscopic origins of terahertz (THz) vibrational modes in biological systems are an active and open area of current research. Recent experiments [ Physical Review X 8, 031061 (2018)] have revealed the presence of a pronounced mode at ∼ 0.3 THz in fluorophore-decorated bovine serum albumin (BSA) protein in aqueous solution under nonequilibrium conditions induced by optical pumping. This result was heuristically interpreted as a collective elastic fluctuation originating from the activation…

From Micro to Macro: A Relativistic Treatment of the Chiral Energy Shifts Caused by Static Electromagnetic Effects on Free Electrons

Free electron systems are ubiquitous in nature and have demonstrated intriguing effects in their collective interactions with weak electric and magnetic fields, especially in aqueous environments.



Dissecting the THz spectrum of liquid water from first principles via correlations in time and space

This result provides a molecular mechanism explaining the experimentally determined sensitivity of absorption changes in the THz domain in terms of distinct, solute-induced dynamical properties in solvation shells of (bio)molecules—even in the absence of well-defined resonances.

Terahertz radiation induces non-thermal structural changes associated with Fröhlich condensation in a protein crystal

This work presents the first experimental observation of Fröhlich condensation in a protein structure using terahertz techniques with a highly sensitive X-ray crystallographic method to visualize low-frequency vibrational modes in the protein structure of hen-egg white lysozyme.

Sub-terahertz spectroscopy reveals that proteins influence the properties of water at greater distances than previously detected.

The derived estimate of hydration shell thickness for each protein supports previous findings that protein-water interaction dynamics extends beyond 2-3 water solvation-layers as predicted by molecular dynamics simulations and other techniques such as NMR, X-ray scattering, and neutron scattering.

Watching the low-frequency motions in aqueous salt solutions: the terahertz vibrational signatures of hydrated ions.

A systematic terahertz absorption spectroscopy and molecular dynamics simulation study of a series of aqueous solutions of divalent salts, which adds a new piece to the puzzle of ion hydration.

Quantum Fluctuations in the Fröhlich Condensate of Molecular Vibrations Driven Far From Equilibrium.

The energy redistribution among vibrational modes with nonlinearity included is shown to be essential for realizing the condensate and the phonon-number distribution, revealing the transition from quasithermal to super-Poissonian statistics with the pump.

Out-of-Equilibrium Collective Oscillation as Phonon Condensation in a Model Protein

We describe the activation of out-of-equilibrium collective oscillations of a macromolecule as a classical phonon condensation phenomenon. If a macromolecule is modeled as an open system-that is, it

Energy transfer to the phonons of a macromolecule through light pumping

In the present paper we address the problem of the energy downconversion of the light absorbed by a protein into its internal vibrational modes. We consider the case in which the light receptors are

New insights into the role of water in biological function: studying solvated biomolecules using terahertz absorption spectroscopy in conjunction with molecular dynamics simulations.

This work highlights recent findings that show the significance of hydrogen bond dynamics for the function of antifreeze proteins and for molecular recognition, and provides new evidence for a specific water-protein coupling as the cause of the observed dynamical heterogeneity.

Ion Hydration and Ion Pairing as Probed by THz Spectroscopy.

This study provides evidence for a non-additive behavior, thus questioning the simplified Hofmeister model, and introduces THz-FTIR spectroscopy as a powerful method to answer the open questions about ion hydration.
