Ramsey interferometry is a widely used tool for precisely measuring transition frequencies between two energy levels of a quantum system, with applications in time keeping, precision spectroscopy, quantum optics, and quantum information. Often, the c

Charles F. Roos, Harold T. Davis and the Quantitative Approach to Business Cycle Analysis at the Cowles Commission in the 1930s and early 1940s∗

Autor: William Veloce, Robert W. Dimand

Publikováno v: The European Journal of the History of Economic Thought. 14:519-542

While much has been written about the history of the Cowles Commission for Research in Economics after its move from Colorado Springs to Chicago in 1939, its earlier history under the first two Cowles Commission research directors, Charles F. Roos an

Sideband Thermometry of Ion Crystals

Autor: Ivan Vybornyi, Laura S. Dreissen, Dominik Kiesenhofer, Helene Hainzer, Matthias Bock, Tuomas Ollikainen, Daniel Vadlejch, Christian F. Roos, Tanja E. Mehlstäubler, Klemens Hammerer

Publikováno v: PRX Quantum, Vol 4, Iss 4, p 040346 (2023)

Coulomb crystals of cold trapped ions are a leading platform for the realization of quantum processors and quantum simulations and, in quantum metrology, for the construction of optical atomic clocks and for fundamental tests of the standard model. F

Observation of Magnon Bound States in the Long-Range, Anisotropic Heisenberg Model

Autor: Florian Kranzl, Stefan Birnkammer, Manoj K. Joshi, Alvise Bastianello, Rainer Blatt, Michael Knap, Christian F. Roos

Publikováno v: Physical Review X, Vol 13, Iss 3, p 031017 (2023)

Over the recent years, coherent, time-periodic modulation has been established as a versatile tool for realizing novel Hamiltonians. Using this approach, known as Floquet engineering, we experimentally realize a long-ranged, anisotropic Heisenberg mo
