Abstract Coulomb repulsion among conduction electrons in solids hinders their motion and leads to a rise in resistivity. A regime of electronic phase separation is expected at the first-order phase transition between a correlated metal and a paramagn

Despite the apparent simplicity of a H2O molecule, the mutual ferroelectric ordering of the molecules is unresolved. Here, the authors realize a macroscopic ferroelectric phase transition in a network of dipole-dipole coupled water molecules located

We measure the real part ε^{′} of the dielectric permittivity of beryl crystals with heavy water molecules D_{2}O confined in nanosized cages formed by an ionic crystal lattice. The experiments are performed at a frequency of 1 MHz in the temperat

We studied the broadband optical conductivity of CaMnBi2, a material with two-dimensional Dirac electronic bands, and found that both components of the intraband conductivity follow a universal power law as a function of frequency at low temperatures

Ferroelectric orders hardly exist in liquid or ice state of water, despite its enormous molecular electrical polarizability. Here, Gorshunov et al. report incipient ferroelectricity in chains of interacting water molecules by placing them in the stru

The properties of organic conductors are often tuned by the application of chemical or external pressure, which change orbital overlaps and electronic bandwidths while leaving the molecular building blocks virtually unperturbed. Here, we show that, u

We measured the reflectivity of the multifold semimetal RhSi in a frequency range from 80 to 20000cm^{−1} (10 meV–2.5 eV) at temperatures down to 10 K. The optical conductivity, calculated from the reflectivity, is dominated by the free-carrier (

We present a far-infrared magneto-optical study of the gapped nodal-line semimetal ZrSiS in magnetic fields B up to 7 T. The observed field-dependent features, which represent intra- (cyclotron resonance) and interband transitions, develop as sqrt[B]

The theoretical and experimental aspects of the microwave, terahertz, and infrared properties of superconductors are discussed. Electrodynamics can provide information about the superconducting condensate as well as about the quasiparticles. The aim

Charge order affects most of the electronic properties but is believed not to alter the spin arrangement since the magnetic susceptibility remains unchanged. We present electron-spin-resonance experiments on quasi-one-dimensional (TMTTF)2X salts (X=
