Phase separation in strongly correlated electron systems with wide and narrow bands: a comparison of the Hubbard-I and DMFT approximations
A. O. Sboychakov
The spinless Falicov-Kimball model on the simple cubic lattice is analyzed in the Hubbard-I and dynamical mean field (DMFT) approximations. The Matsubara and real frequency itinera…
Superradiance of a 2D-spaser array
A. V. Dorofeenko, A. A. Zyablovsky, A. P. Vinogradov +3
We demonstrate that interacting spasers arranged in a 2D array of arbitrary size can be mutually synchronized allowing them to supperradiate. For arrays smaller than the free space…
Phase separation of antiferromagnetic ground states in systems with imperfect nesting
A. L. Rakhmanov, A. V. Rozhkov, A. O. Sboychakov +1
We analyze the phase diagram for a system of weakly-coupled electrons having an electron- and a hole-band with imperfect nesting. Namely, both bands have spherical Fermi surfaces,…
Loss compensation by spasers in metamaterials
E. S. Andrianov, D. G. Baranov, A. A. Pukhov +3
We show that exact loss compensation can be achieved in active metamaterials containing spasers pumped over a wide range of pumping values both below and above the spasing threshol…
Excited states in Richardson pairing model: `probabilistic' approach
W. V. Pogosov
Richardson equations can be mapped on the classical electrostatic problem in two dimensions. We have recently suggested a new analytical approach to these equations in the thermody…
Two-qubit parametric amplifier: large amplification of weak signals
S. Savel'ev, A. M. Zagoskin, A. L. Rakhmanov +3
Using numerical simulations, we show that two coupled qubits can amplify a weak signal about hundredfold. This can be achieved if the two qubits are biased simultaneously by this w…
Pecularities of Hall effect in GaAs/δ<Mn>/GaAs/In\timesGa1-\timesAs/GaAs (\times {\approx} 0.2) heterostructures with high Mn content
M. A. Pankov, B. A. Aronzon, V. V. Rylkov +9
Transport properties of GaAs/δ<Mn>/GaAs/In\timesGa1-\timesAs/GaAs structures containing InxGa1-xAs (\times {\approx} 0.2) quantum well (QW) and Mn delta layer (DL) with relatively…
Noise studies of magnetization dynamics in dilute magnetic semiconductor heterostructures
V. Tripathi, Kusum Dhochak, B. A. Aronzon +3
We study theoretically and experimentally the frequency and temperature dependence of resistivity noise in semiconductor heterostructures delta-doped by Mn. The resistivity noise i…
Macroscopic quantum tunneling and phase diffusion in a LaSrCuO intrinsic Josephson junction stack
Yuimaru Kubo, A. O. Sboychakov, Franco Nori +5
We performed measurements of switching current distribution in a submicron LaSrCuO (LSCO) intrinsic Josephson junction (IJJ) stack in a wide temperature range. The…
