Merging of Landau levels in a strongly interacting two-dimensional electron system in silicon.

Physical review letters

Shashkin AA, Dolgopolov VT, Clark JW, Shaginyan VR, Zverev MV, Khodel VA.
PMID: 24856708
Phys Rev Lett. 2014 May 09;112(18):186402. doi: 10.1103/PhysRevLett.112.186402. Epub 2014 May 08.

We show that the merging of the spin- and valley-split Landau levels at the chemical potential is an intrinsic property of a strongly interacting two-dimensional electron system in silicon. Evidence for the level merging is given by available experimental...

Quantization of the Hall conductivity well beyond the adiabatic limit in pulsed magnetic fields.

Physical review letters

Dolgopolov VT, Shashkin AA, Broto JM, Rakoto H, Askenazy S.
PMID: 11415302
Phys Rev Lett. 2001 Jun 11;86(24):5566-9. doi: 10.1103/PhysRevLett.86.5566.

We measure the Hall conductivity, sigma(xy), on a Corbino geometry sample of a high-mobility AlGaAs/GaAs heterostructure in a pulsed magnetic field. At a bath temperature about 80 mK, we observe well expressed plateaux in sigma(xy) at integer filling factors....

Stimulated scattering of indirect excitons in coupled quantum wells: signature of a degenerate Bose-gas of excitons.

Physical review letters

Butov LV, Ivanov AL, Imamoglu A, Littlewood PB, Shashkin AA, Dolgopolov VT, Campman KL, Gossard AC.
PMID: 11415313
Phys Rev Lett. 2001 Jun 11;86(24):5608-11. doi: 10.1103/PhysRevLett.86.5608.

We observe and analyze strongly nonlinear photoluminescence kinetics of indirect excitons in GaAs/AlGaAs coupled quantum wells at low bath temperatures, > or = 50 mK. The long recombination lifetime of indirect excitons promotes accumulation of these Bose particles in...

Numerical investigation of thermally induced birefringence in optical elements of solid-state lasers.

Applied optics

Parfenov V, Shashkin V, Stepanov E.
PMID: 20856332
Appl Opt. 1993 Sep 20;32(27):5243-55. doi: 10.1364/AO.32.005243.

We have developed a method of computational simulation and estimation of thermo-optical distortions in solid-state laser rods, electro-optic shutters, and modulators, considering real heat-transfer conditions, anisotropic material properties, and an arbitrary cross-section shape of the element. Numerical investigations for...

Phys Rev Lett. 2012 Aug 31;109(9):096405. doi: 10.1103/PhysRevLett.109.096405. Epub 2012 Aug 28.

With decreasing density n(s) the thermopower S of a low-disorder two-dimensional electron system in silicon is found to exhibit a sharp increase by more than an order of magnitude tending to a divergence at a finite disorder-independent density n(t)...
