Theoretical prediction of improved figure-of-merit in Si/Ge quantum dot superlattices
New Journal of Physics, 2013 A detailed theoretical model for thermoelectric transport perpendicular to the multilayers of a Si–Ge heterostructure is presented. The electronic structure of a three-dimensional superlattice, consisting of a regular array of Ge quantum dots in each ...

, 2017 A manifestation of electron-hole pairing in nonlinear electromagnetic response of a double layer graphene system is studied. It is shown that the pairing causes the appearance of a number of peaks in the frequency dependence of the intensity of the third

Nonlinear chiral transport from holography
, 2019 Nonlinear transport phenomena induced by the chiral anomaly are explored within a 4D field theory defined holographically as $U(1)_V\times U(1)_A$ Maxwell-Chern-Simons theory in Schwarzschild-$AdS_5$. First, in presence of external electromagnetic fields,

Nonlinear Nonreciprocal Electric Conductivity Driven by Magnetic Field Gradients
Journal of the Physical Society of JapanWe theoretically propose the emergence of nonlinear nonreciprocal conductivity in centrosymmetric paramagnetic systems when a spatially gradient magnetic field is externally applied. The key essence lies in the appearance of magnetic toroidal dipole moment under the gradient field that breaks both spatial inversion and time-reversal symmetries.

Emergence of domains and nonlinear transport in the zero-resistance state
, 2013 We study transport in the domain state, the so-called zero-resistance state, that emerges in a two-dimensional electron system in which the combined action of microwave radiation and magnetic field produces a negative absolute conductivity.

Electronic Journal of Differential Equations, 2009 The steady motion of a viscous fluid in pipes of arbitrary cross-sections under a transverse magnetic field is studied, assuming that the viscosity and the electric and thermal conductivity are given functions of the temperature. Theorems of existence

Influence of optical nonlinearities on plasma waves in graphene
, 2017 A theory of the nonlinear plasma waves in graphene is developed in the nonperturbative regime. The influence of strong electric fields on the position and linewidth of plasma resonances in the far-infrared transmission experiments, as well as on the ...
