Erweiterte Suche der Leibniz Universität Hannover

The "Welfenschloss" Foto: Philip Bartz / LUH The heart of Leibniz Universität Hannover beats in the idyllic Welfenschloss, the Guelph Palace. The year 1879 saw the Higher Vocational School, originally founded in 1831, move into the palace. While 64 pupils first attended the Vocational School, the university now has around 28.000 students.

Conference formats The well known traditional conference formats such as papers and panels, roundtables and plenary sessions are the foundation of the DVRW conference 2019.

In particular, coherence of such systems, in the context of matter-wave interference experiments, can be measurably affected by relativity even at low-energies and in weak gravitational fields through time dilation [1-4]. Testing validity of the EEP in quantum theory requires testing equivalence of the internal energy operators. [5] M. Zych, and C.

Quantum sensing limits from energy, space and time Morgan W. Mitchell1, 2 1 ICFO-Institut de Ciencies Fotoniques, The Barcelona Institute of Science and Technology, 08860 Castelldefels (Barcelona), Spain. We describe a class of quantum sensing limits that – unlike the standard quantum limit and Heisenberg limit – make no reference to particle number [1]. Rather, these “energy resolution limits” constrain 𝐸𝐸𝑅𝑅, the energy resolution per bandwid...

Quantum metrology with Rydberg atoms S. Gleyzes1, A. Larrouy1, S. Patsch2, R. Richaud1, J.M. It is possible to manipulate the state of the atom using an rf field with a well-defined polarization to prepare states with large electric or magnetic dipole. In our experiment, we generate Schrödinger cat states of the Rydberg atom of rubidium by preparing quantum superposition of two trajectories with very different classical property. The relative ...

Our value can then be p d compared with the combined results from atomic hydrogen spectroscopy and mass spectrometry in Penning traps [7, 8]. The results of the analysis will be presented at the conference. Fig. 1. 6 hyperfine components of the fundamental rotational transition. The line center frequencies of the components differ by values of the order 10 MHz.

Tests of quantum mechanics and gravitation with atom interferometry P. Asenbaum, J. Martinez, B. Pichler, Y. Wu, T. Kovachy, J. Hogan and M. Kasevich Dept. of Physics and Applied Physics, Stanford University, Stanford CA Abstract: Recent de Broglie wave interference experiments with atoms have achieved wavepacket separations as large as 54 cm over time intervals of 2 sec [1, 2]. These experiments, and their impact on gravitational and quantum ...

The MPO formalism allows for spatial and temporal noise correlations, in particular, one may determine the maximal achievable estimation precision in such models, as well as the optimal probe states in p...

We propose to use a three-photon CPT to reach spectroscopy in the THz domain, which is so far associated to rotation transitions in light molecules. When fulfilled, the three-photon resonance condition implies a relation between the three laser frequencies and the frequency of the 1.82 THz magnetic dipole transition between the two fine-structure terms of the 3D level, which appears as the atomic reference for the dark line. Basing a THz refer...

Testing of Quantum Gravity with ~kg scale acoustic resonators A.P. The prediction of most of the QG theories (such as, string theory) and the physics of black holes lead to the existence of the minimum measurable length set by the Plank length. The latter is equivalent to the non-linear modification of the Hamiltonian and results in the dependence of the oscillator resonance frequency on its energy [3]. Therefore, the remarkable high-Q and fre...
