Incommensurate magnetic order and phase separation in the two-dimensional Hubbard model with nearest and next-nearest neighbor hopping
P. A. Igoshev, M. A. Timirgazin, A. A. Katanin +2
We consider the ground state magnetic phase diagram of the two-dimensional Hubbard model with nearest and next-nearest neighbor hopping in terms of electronic density and interacti…
Sensitivity of microwave and FIR spectra to variation of fundamental constants
M. G. Kozlov, A. V. Lapinov, S. A. Levshakov
We estimate sensitivity coefficients to variation of the fine-structure constant alpha and electron-to-proton mass ratio mu for microwave Lambda-type transitions in CH molecule and…
Manifestation of the strong quadrupole light-molecule interaction in the SEHR spectra of symmetrical molecules
A. M. Polubotko
The paper demonstrates possibility of giant enhancement of Surface Enhanced Hyper Raman Scattering on the base of qualitative consideration of electromagnetic field near some model…
Directional Radiation and Photodissociation Regions in Molecular Hydrogen Clouds
S. A. Balashev, D. A. Varshalovich, A. V. Ivanchik
Some astrophysical observations of molecular hydrogen point to a broadening of the velocity distribution for molecules at excited rotational levels. This effect is observed in both…
A solar cycle lost in 1793--1800: Early sunspot observations resolve the old mystery
Ilya G. Usoskin, Kalevi Mursula, Rainer Arlt +1
Because of the lack of reliable sunspot observation, the quality of sunspot number series is poor in the late 18th century, leading to the abnormally long solar cycle (1784--1799)…
Pump-Probe Faraday Rotation and Ellipticity in an Ensemble of Singly Charged Quantum Dots
I. A. Yugova, M. M. Glazov, E. L. Ivchenko +1
A description of spin Faraday rotation, Kerr rotation and ellipticity signals for single- and multi-layer ensembles of singly charged quantum dots (QDs) is developed. The microscop…
Electron-electron scattering effect on spin relaxation in multi-valley nanostructures
M. M. Glazov, E. L. Ivchenko
We develop a theory of effects of electron-electron collisions on the Dyakonov-Perel' spin relaxation in multi-valley quantum wells. It is shown that the electron-electron scatteri…
On the spectrum of the periodic Dirac operator
L. I. Danilov
The absolute continuity of the spectrum for the periodic Dirac operator $$ \hat D=\sum_{j=1}^n(-i\frac {\partial}{\partial x_j}-A_j)\hat α_j + \hat V^{(0)}+\hat V^{(1)}, x\in R^n,…
Nuclear fusion reaction rates for strongly coupled ionic mixtures
A. I. Chugunov, H. E. De Witt
We analyze the effect of plasma screening on nuclear reaction rates in dense matter composed of atomic nuclei of one or two types. We perform semiclassical calculations of the Coul…
Models of magnetized neutron star atmospheres: thin atmospheres and partially ionized hydrogen atmospheres with vacuum polarization
V. F. Suleimanov, A. Y. Potekhin, K. Werner
Observed X-ray spectra of some isolated magnetized neutron stars display absorption features, sometimes interpreted as ion cyclotron lines. Modeling the observed spectra is necessa…
Decoherence in qubits due to low-frequency noise
J Bergli, Y M Galperin, B L Altshuler
The efficiency of the future devices for quantum information processing is limited mostly by the finite decoherence rates of the qubits. Recently a substantial progress was achieve…
Restoring integrability in one-dimensional quantum gases by two-particle correlations
I. E. Mazets, J. Schmiedmayer
We show that thermalization and the breakdown of integrability in the one dimensional Lieb-Liniger model caused by local three-body elastic interactions is suppressed by pairwise q…
Density ripples in expanding low-dimensional gases as a probe of correlations
A. Imambekov, I. E. Mazets, D. S. Petrov +6
We investigate theoretically the evolution of the two-point density correlation function of a low-dimensional ultracold Bose gas after release from a tight transverse confinement.…
Fano Resonance Between Mie and Bragg Scattering in Photonic Crystals
M. V. Rybin, A. B. Khanikaev, M. Inoue +4
We report the observation of a Fano resonance between continuum Mie scattering and a narrow Bragg band in synthetic opal photonic crystals. The resonance leads to a transmission sp…
Reversible state transfer between superconducting qubits and atomic ensembles
D. Petrosyan, G. Bensky, G. Kurizki +3
We examine the possibility of coherent, reversible information transfer between solid-state superconducting qubits and ensembles of ultra-cold atoms. Strong coupling between these…
Spin-orbit effect on electron-electron interaction and fine structure of electron complexes in quantum dots
M. M. Glazov, V. D. Kulakovskii
Spin-orbit effects on electron-electron interaction are studied theoretically. The corrections to the Coulomb interaction of quantum well electrons induced by the spin-orbit coupli…
