Nonlinear bending of molecular films by polarized light
Yu. B. Gaididei, A. P. Krekhov, H. Buettner
A theory of photoinduced directed bending of non-crystalline molecular films is presented. Our approach is based on elastic deformation of the film due to interaction between molec…
Non-Markovian decoherence and disentanglement scenarios in quantum Brownian motion
C. Hoerhammer, H. Buettner
We study the non-Markovian decoherence and disentanglement dynamics of dissipative quantum systems with special emphasis on non-Gaussian continuous variable systems. The dynamics a…
Environment-induced two-mode entanglement in quantum Brownian motion
C. Hoerhammer, H. Buettner
The time evolution of quantum correlations of entangled two-mode continuous variable states is examined in single-reservoir as well as two-reservoir models, representing noisy corr…
Coexistence of polar order and local domain dynamics in ferroelectric SrTi18O3
A. Bussmann-Holder, H. Buettner, A. R. Bishop
Perovskite oxide ferroelectrics show classical soft mode behaviour typical for the onset of a homogeneous long-range polar state and a displacive phase transition. Besides these lo…
Polynomial invariants and Bell inequalities as entanglement measure of 4-qubit states
Jochen Endrejat, Helmut Buettner
We compare the polynomial invariants for four qubits introduced by Luque and Thibon, PRA {\bf 67}, 042303 (2003), with optimized Bell inequalities and a combination of two qubit co…
Entanglement measurement with discrete multiple coin quantum walks
Jochen Endrejat, Helmut Buettner
Within a special multi-coin quantum walk scheme we analyze the effect of the entanglement of the initial coin state. For states with a special entanglement structure it is shown th…
