We present theoretical study and numerical simulation of Marangoni convection within ellipsoidal isotropic droplets embedded in free standing smectic films (FSSF). The thermocapill…
Engineering underdoped CuO nanoribbons in nm-thick -axis YBaCuO films
Riccardo Arpaia, Núria Alcalde-Herraiz, Andrea D'Alessio +5
In underdoped cuprate high superconductors, various local orders and symmetry breaking states, in addition to superconductivity, reside in the CuO planes. The…
Evidence of electronic phase separation in the strongly correlated semiconductor YbB12
A. Azarevich, N. Bolotina, O. Khrykina +9
The studies of high-quality single-domain crystals of YbB12 were carried out by the precise x-ray diffraction technique in combination with the low temperature polarized THz - infr…
Size-dependent thermal stability and optical properties of ultra-small nanodiamonds synthesized under high pressure
E. A. Ekimov, A. A. Shiryaev, Yu. Grigoriev +4
Diamond properties down to the quantum-size region are still poorly understood. High-pressure high-temperature (HPHT) synthesis from chloroadamantane molecules allows precise contr…
One-dimensional quasi bound states in the continuum in the ω~k space for nonlinear optical applications
