## Finite-frequency response of Rasba electron gas with two-particle scattering

Physical Review B: Condensed Matter and Materials Physics. 2021. Vol. 104. Article 075423.

Nagaev K.

Two-dimensional systems with Rashba spin-orbit coupling are not Galilean invariant and therefore electron–

electron collisions in them may affect the current. However, when taken alone, they cannot ensure a nonzero

dc resistivity, so their effects are masked by impurity scattering. Here we calculate the related finite-frequency

response and show that the electron–electron scattering in clean Rashba conductors decreases the Drude weight while resulting in a finite dissipative component of the response outside of the Drude peak.

Semimetal states of crystalline molecular hydrogen have been obtained at a temperature of 100 K in the pressure
range from 410 to 626 GPa. To analyze the nature of conductivity, the band structure is calculated in the
framework of the density functional theory using the Heyd–Scuseria–Ernzerhof hybrid exchange-correlation
functional. One of the semimetal states occurs in a monoclinic ...

Electron-electron collisions are known to cause a nonlocal voltage drop in the presence of current flow. The
semiphenomenological theory predicts this drop to be opposite to the direction of the current in the ballistic
regime. We use a microscopic approach and show that the sign of this drop may be of both signs depending
on the temperature and ...

Two techniques of manufacturing a nanocomposite based on a complex of polyaniline with polymer acid and graphene are proposed. The electric conductivity of thin nanocomposite layers is higher than that of a polymer complex of polyaniline and strongly depends on the degree of oxidation of graphene. An explanation of the effect is suggested that takes ...

Composites based on graphene and water-dispersible polyaniline-poly(2-acrylamido-2-methyl-1-propanesulfonic acid) complex were shown as materials promising for the development of hole transporting layers (HTLs). By using multimodal atomic force microscopy, transmission electron microscopy, cyclic voltammetry and conductivity measurements, the relationship between the oxidation degree of graphene and the morphology, electrical conductivity and electron energy structure of HTLs was revealed. Utilizing the ...

We calculate the electrical and thermal conductivity of a two-dimensional electron gas with strong spin-orbit
coupling in which the scattering is dominated by electron-electron collisions. Despite the apparent absence of
Galilean invariance in the system, the two-particle scattering does not affect the electrical conductivity above
the band-crossing point where both helicity bands are filled. Below the band-crossing point ...

Warm dense matter (WDM) is a state of a substance with a solid-state density and temperature from 1 to 100 eV. Researchers believe that such a state exists in the cores of giant planets. Investigation of WDM is important for some applications, such as surface treatment on the nanometer scale, laser ablation, and the formation ...

Warm dense matter conductivity and reflectivity are investigated by means of density functional theory. Both one- and two-temperature cases are considered. One-temperature mode is related to equilibrium state where temperature of electrons and ions are equal. As an example of one-temperature system xenon plasma is studied. The reflectivity of shock-compressed dense xenon plasma is calculated ...

We study regularization scheme dependence of beta-function for sigma models with two-dimensional target space. Working within four-loop approximation, we conjecture the scheme in which the beta-function retains only two tensor structures up to certain terms containing zeta_3. Using this scheme, we provide explicit solutions to RG flow equation corresponding to Yang-Baxter- and lambda-deformed SU(2)/U(1) sigma ...

In this short review, we first discuss the results, which are mainly devoted to the generalizations of the famous Kohn–Luttinger mechanism of superconductivity in purely repulsive fermion systems at low electron densities. In the context of repulsive-U Hubbard model and Shubin–Vonsovsky model we consider briefly the superconducting phase diagrams and the symmetries of the order parameter ...

In this work, we present for the first time the Lyman α intensities measured by Voyager 1/UVS in 2003–2014 (at 90–130 AU from the Sun). During this period Voyager 1 measured the Lyman α emission in the outer heliosphere at an almost fixed direction close to the upwind (i.e.“ toward the interstellar flow). The data show an unexpected behavior in 2003–2009: the ...

To date, a number of lantibiotics have been shown to use lipid II — a highly conserved peptidoglycan precursor in the cytoplasmic membrane of bacteria — as their molecular target. The α-component (Lchα) of the two-component lantibiotic lichenicidin (Lchα), previously isolated from the Bacillus licheniformis VK21 strain, seems to contain two putative lipid II binding ...

The framework of simple opposition realism - anti-realism is not enough to analyze the views on the reality of unobservable objects of quantum theory. First, it is necessary to distinguish between realism in relation to the theory and realism in relation to the theory’s objects. Secondly, realism in relation to classical objects can be combined, ...

states when N receivers are separately located. In this report, we propose optical designs that can
perform sequential state discrimination of two coherent states. For this purpose, we consider not
