Studies of the electromagnetic response of various classes of correlated electron materials
including transition-metal oxides, organic and molecular conductors, intermetallic …

In conventional ferroelectrics the polarization is induced either by the relative displacement
of positive and negative ions due to a lattice distortion or by the collective alignment of …

This review provides a perspective on recent developments and their implications for our
understanding of novel quantum phenomena in the physics of two-dimensional organic …

Utilizing infrared vibrational spectroscopy we have investigated dimerized two-dimensional
organic salts in order to search for possible charge redistribution that might constitute …

This short review article provides the reader with a summary of the history of organic
conductors. To retain a neutral and objective point of view regarding the history …

We report on the anisotropic response, the charge and lattice dynamics of normal and
charge ordered phases with horizontal stripes in single crystals of the organic conductor α …

Organic metals exhibit unusual electronic properties in their charge and spin degrees of
freedom that have puzzled physicists for decades. By now this behaviour is established as …

Charge ordering in the (TMTTF) 2 X salts with centrosymmetric anions (X= PF 6−, AsF 6−,
SbF 6−) leads to a ferroelectric state around 100 K. For the first time and in great …

Infrared optical investigations of α-(BEDT-TTF) 2 I 3 have been performed in the spectral
range from 80 to 8000 cm− 1 down to temperatures as low as 10 K by applying hydrostatic …

A complete analysis of the vibrational dynamics of the most important molecule in the field of
organic superconductors, bis (ethylenedithio)-tetrathiafulvalene (BEDT-TTF), has been …
