Growth of surface undulations at the Rosensweig instability
Holger Knieling, Reinhard Richter, Ingo Rehberg +2
We investigate the growth of a pattern of liquid crests emerging in a layer of magnetic liquid when subjected to a magnetic field oriented normally to the fluid surface. After a st…
A Raman study of the Charge-Density-Wave State in AMoO (A = K,Rb)
D. M. Sagar, D. Fausti, S. Yue +3
We report a comparative Raman spectroscopic study of the quasi-one-dimensional charge-density-wave systems \ab (A = K, Rb). The temperature and polarization dependent experiments r…
Dynamic probes of quantum spin chains with the Dzyaloshinskii-Moriya interaction
Oleg Derzhko, Taras Verkholyak, Taras Krokhmalskii +1
We consider the spin-1/2 anisotropic XY chain in a transverse (z) field with the Dzyaloshinskii-Moriya interaction directed along z-axis in spin space to examine the effect of the…
Coherent backscattering of light from saturated atoms
Vyacheslav Shatokhin, Thomas Wellens, Cord Müller +1
We survey recent progress achieved in understanding the impact of inelastic processes on coherent backscattering of light from cold atoms that are saturated by a powerful laser fie…
Information and entropy in quantum Brownian motion: Thermodynamic entropy versus von Neumann entropy
Christian Hoerhammer, Helmut Buettner
We compare the thermodynamic entropy of a quantum Brownian oscillator derived from the partition function of the subsystem with the von Neumann entropy of its reduced density matri…
Use of resonance Raman spectroscopy to study the phase diagram of PbZr0.52Ti0.48O3
Jerome Rouquette, Julien Haines, Véronique Bornand +3
Evidence is presented for the first time that the sharp and continuous spectral changes observed in PbZr0.52Ti0.48O3 (PZT) between 350 and 10 K with the 647.1 nm wavelength are due…
