CMB Alignment in Multi-Connected Universes
R. Aurich, S. Lustig, F. Steiner +1
The low multipoles of the cosmic microwave background (CMB) anisotropy possess some strange properties like the alignment of the quadrupole and the octopole, and the extreme planar…
Persistent currents through a quantum impurity: Protection through integrability
Johan Nilsson, H. -P. Eckle, Henrik Johannesson
We consider an integrable model of a one-dimensional mesoscopic ring with the conduction electrons coupled by a spin exchange to a magnetic impurity. A symmetry analysis based on a…
Self-rotating wave approximation via symmetric ordering of ladder operators
Jonas Larson, Hector Moya-Cessa
We show how some Hamiltonians may be approximated using rotating wave approximation methods. In order to achieve this we use the algebra of boson ladder operators, and transformati…
Dropping cold quantum gases on Earth over long times and large distances
G. Nandi, R. Walser, E. Kajari +1
We describe the non-relativistic time evolution of an ultra-cold degenerate quantum gas (bosons/fermions) falling in Earth's gravity during long times (10 sec) and over large dista…
Collaborative Decoding of Interleaved Reed-Solomon Codes and Concatenated Code Designs
Georg Schmidt, Vladimir R. Sidorenko, Martin Bossert
Interleaved Reed-Solomon codes are applied in numerous data processing, data transmission, and data storage systems. They are generated by interleaving several codewords of ordinar…
Persistence of Quantum Information
Michael Schulz, Steffen Trimper
There is an increasing interest in the role of macroscopic environments to our understanding of the basics of quantum theory. The knowledge of the implications of the quantum theor…
