Superconductivity in two-band systems with variable charge carrier density. The case of MgB2
M. E. Palistrant, V. A. Ursu
The theory of thermodynamic properties of two-band superconductor with reduced density charge carriers is developed on the base of phonon superconducting mechanism with strong elec…
Radiation Emission by Extreme Relativistic Electrons and Pair Production by Hard Photons in a Strong Plasma Wakefield
E. Nerush, I. Kostyukov
Radiation spectrum of extreme relativistic electrons and a probability of electron-positron pair production by energetic photons in a strong plasma wakefield are derived in the fra…
Synchrotron emission in the fast cooling regime: which spectra can be explained?
E. V. Derishev
We consider the synchrotron emission from relativistic shocks assuming that the radiating electrons cool rapidly (either through synchrotron or any other radiation mechanism). It i…
Spin-phonon coupling in ZnCr2Se4
T. Rudolf, Ch. Kant, F. Mayr +3
Spin-phonon coupling and magnetodielectric effects of ZnCr2Se4 were investigated by means of infrared (IR) spectroscopy as a function of temperature and magnetic field. ZnCr2Se4 is…
Complexity of Self-similar Hierarchical Ensembles
A. I. Olemskoi
Within the framework of generalized combinatorial approach, the complexity is determined for infinite set of self-similar hierarchical ensembles. This complexity is shown to increa…
Multiferroicity and colossal magneto-capacitance in Cr-thiospinels
J. Hemberger, P. Lunkenheimer, R. Fichtl +3
The sulfur based Cr-spinels RCr2S4 with R = Cd and Hg exhibit the coexistence of ferromagnetic and ferroelectric properties together with a pronounced magnetocapacitive coupling. W…
Chemical differentiation in regions of high-mass star formation I. CS, dust and N2H^+ in southern sources
L. Pirogov, I. Zinchenko, P. Caselli +1
Aims. Our goals are to compare the CS, N2H+ and dust distributions in a representative sample of high-mass star forming dense cores and to determine the physical and chemical prope…
Colossal magnetostriction and negative thermal expansion in the frustrated antiferromagnet ZnCr2Se4
J. Hemberger, H. -A. Krug von Nidda, V. Tsurkan +1
A detailed investigation of ZnCr2Se4 is presented which is dominated by strong ferromagnetic exchange but orders antiferromagnetically at T_N = 21 K. Specific heat C and thermal ex…
Anomalous bond stretching phonons as a probe of charge fluctuations in perovskites
S. Cojocaru, R. Citro, M. Marinaro
Important information on momentum resolved low energy charge response can be extracted from anomalous properties of bond stretching in plane phonons observed in inelastic neutron a…
Verification of bootstrap conditions for amplitudes with quark exchanges in QMRK
A. V. Bogdan, A. V. Grabovsky
The compatibility of the multi--Regge form of QCD amplitudes in the quasi--multi--Regge kinematics (QMRK) and the s--channel unitarity imposes some constraints on the effective jet…
Fluctuations in Ideal and Interacting Bose-Einstein Condensates: From the laser phase transition analogy to squeezed states and Bogoliubov quasiparticles
Vitaly V. Kocharovsky, Vladimir V. Kocharovsky, Martin Holthaus +4
We review the phenomenon of equilibrium fluctuations in the number of condensed atoms in a trap containing N atoms total. We start with a history of the Bose-Einstein distribution,…
Off-axis emission from relativistic plasma flows
E. V. Derishev, F. A. Aharonian, Vl. V. Kocharovsky
We show that there is no universal law describing how the spectra and luminosity of synchrotron and inverse Compton radiation from relativistic jets change with increasing observat…
