On the Quasi-Periodic Oscillations of Magnetars (2009)

Colaiuda, A., Beyer, H., Kokkotas, K. D.

We study torsional Alfv\'en oscillations of magnetars, i.e., neutron stars with a strong magnetic field. We consider the poloidal and toroidal components of the magnetic field and a wide range of...

Study of electron bremsstrahlung in strong coulomb fields at the ESR storage ring (2007)

Ludziejewski Th, Th. Stohlker, S. Keller, H. Beyer, F. Bosch, O. Brinzanescu, ...

Electron bremsstrahlung has been investigated for collisions of 223.2 MeV/amu He-like uranium ions with N 2 and Ar gaseous targets. The doubly differential cross-sections for bremsstrahlung are...

Torsional Oscillations of Slowly Rotating Relativistic Stars (2007)

Vavoulidis, M., Stavridis, A., Kokkotas, K. D., Beyer, H.

We study the effects of rotation on the torsional modes of oscillating relativistic stars with a solid crust. Earlier works in Newtonian theory provided estimates of the rotational corrections for...

Verfahren und Vorrichtung zur schnellen Messung hoher Gangunterschiede von durchsichtigen und optisch doppelbrechenden Medien ohne und mit Falschfarben in Kleinstraeumen nach Senarmont (2004)

Kaufmann, S., Schache, H., Zeitner, U., Beyer, H.

DE 10245407 A UPAB: 20040514 NOVELTY - Device for automatically measuring high cycle differences in permeable and optically birefringent media with simultaneous digital Fourier analysis comprises a...

High thermoelectric figure of merit ZT in PbTe and Bi/sub 2/Te/sub 3/-based superlattices by a reduction of the thermal conductivity (2002)

Beyer, H., Nurnus, J., Böttner, H., Lambrecht, A., Wagner, E., Bauer, G.

Experimental evidence is presented for an enhanced thermoelectric figure of merit ZT = sigma S/sup 2/T/ lambda (where sigma is the electrical conductivity, S the thermopower, T the temperature, and...

PbTe based superlattice structures with high thermoelectric efficiency (2002)

Beyer, H., Nurnus, J., Böttner, H., Lambrecht, A., Roch, T., Bauer, G.

We report on an enhanced thermoelectric figure of merit ZT=sigmaS(2)T/lambda (where sigma is electrical conductivity, S is thermopower, T is absolute temperature, and lambda is thermal conductivity)...

Thermoelectric Si(1-x)Ge(x) and PbTe thin films for device applications (2002)

Künzel, C., Beyer, H., Braun, M., Feißt, A., Lamprecht, A., Nurnus, J., ...

In order to realize thermoelectric devices for sensors, coolers and energy conversion systems the technology of preparation of thin film thermoelectric materials has to be developed. We describe the...

HEAVY-ION COOLING AND RADIATIVE RECOMBINATION (1989)

Beyer, H.

There is presently a large number of ion storage rings under construction which will use electron cooling for increasing the phase-space density of the stored ions in order to gain luminosity and...

FEW-ELECTRON STATES OF Ne PRODUCED BY 1.4 MeV/amu HEAVY ION IMPACT (1979)

Beyer, H., Folkmann, F.

To study highly ionized atomic states, we have bombarded a Ne gas target with very heavy ions, as Ar12+, Ti14+, Ni16+, Kr18+, Xe24+ and Pb36+ of specific energy 1.4 MeV/amu from the UNILAC at GSI,...
