Results of a theoretical study on non-Markov response for femtosecond laser-driven coherent ring currents in chiral aromatic molecules embedded in a condensed phase are presented. Coherent ring currents are generated by coherent excitation of a pair of quasi-degenerated π-electronic excited states. The coherent electronic dynamical behaviors are strongly influenced by interactions between the e...

We measured the polarized optical conductivity of URu2Si2 from room temperature down to 5 K, covering the Kondo state, the coherent Kondo liquid regime, and the hidden-order phase. The normal state is characterized by an anisotropic behavior between the ab plane and c-axis responses. The ab-plane optical conductivity is strongly influenced by the formation of the coherent Kondo liquid: a sharp ...

Additive force fields are designed to account for induced electronic polarization in a mean-field average way, using effective empirical fixed charges. The limitation of this approximation is cause for serious concerns, particularly in the case of lipid membranes, where the molecular environment undergoes dramatic variations over microscopic length scales. A polarizable force field based on the...

The detailed optical properties of the multiband iron-chalcogenide superconductor FeTe0.55Se0.45 have been reexamined for a large number of temperatures above and below the critical temperature Tc = 14 K for light polarized in the a-b planes. Instead of the simple Drude model that assumes a single band, above Tc the normal-state optical properties are best described by the two-Drude model that ...

The boundary integral equation method is used to prove the convergence of the Drude-Born-Fedorov equations with variable coeecients, possibly non-smooth, to Maxwell's equations as chirality admittance tends to zero.

It is commonly accepted that in typical situations the rate of entropy production non-negative. We show this assertion not entirely correct, even linear regime, if a time-dependent, external perturbation compensated by rapid enough decay response function. This demonstrated for three variants Drude model to describe electrical conduction noble metals, namely classical free electron gas, Drude-S...

The ab-plane optical properties of a cleaved single crystal of La2-xBaxCuO4 for x=1/8 (Tc approximately =2.4 K) have been measured over a wide frequency and temperature range. The low-frequency conductivity is Drude-like and shows a metallic response with decreasing temperature. However, below approximately =60 K, corresponding to the onset of charge-stripe order, there is a rapid loss of spect...

A polarizable empirical force field based on the classical Drude oscillator is presented for the hexopyranose form of selected monosaccharides. Parameter optimization targeted quantum mechanical (QM) dipole moments, solute-water interaction energies, vibrational frequencies, and conformational energies. Validation of the model was based on experimental data on crystals, densities of aqueous-sug...
