Experimental implementation of a four-player quantum game
Christian Schmid, Adrian P. Flitney, Witlef Wieczorek +3
Game theory is central to the understanding of competitive interactions arising in many fields, from the social and physical sciences to economics. Recently, as the definition of i…
CAT(0) and CAT(-1) fillings of hyperbolic manifolds
Koji Fujiwara, Jason Fox Manning
We give new examples of hyperbolic and relatively hyperbolic groups of cohomological dimension for all . These examples result from applying CAT/CAT filling…
Thermal States of Anyonic Systems
S. Iblisdir, D. Perez-Garcia, M. Aguado +1
A study of the thermal properties of two-dimensional topological lattice models is presented. This work is relevant to assess the usefulness of these systems as a quantum memory. F…
Measuring interstellar magnetic fields by radio synchrotron emission
Rainer Beck
Radio synchrotron emission, its polarization and its Faraday rotation are powerful tools to study the strength and structure of interstellar magnetic fields. The total intensity tr…
Adiabatic expansion and magnetic fields in AGN jets
A. B. Pushkarev, Y. Y. Kovalev, A. P. Lobanov
Results of high-resolution simultaneous multi-frequency 8.1-15.4 GHz VLBA polarimetric observations of relativistic jets in active galactic nuclei (the MOJAVE-2 project) are analyz…
Probing parsec scale jets in AGN with geodetic VLBI
A. B. Pushkarev, Y. Y. Kovalev
We report on an ongoing effort to image active galactic nuclei simultaneously observed at 2.3 and 8.6 GHz in the framework of a long-term VLBI project RDV (Research and Development…
