Quantum phase transition from a superfluid to a Mott insulator in a gas of ultracold atoms
Markus Greiner, Olaf Mandel, Tilman Esslinger +2
For a system at a temperature of absolute zero, all thermal fluctuations are frozen out, while quantum fluctuations prevail. These microscopic quantum fluctuations can induce a mac…

The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Klaus Blaum, Peter Kaufmann, Jochen Kronjäger +168
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…

Quantifying hole-motion-induced frustration in doped antiferromagnets by Hamiltonian reconstruction
Henning Schlömer, Timon A. Hilker, Immanuel Bloch +3
Unveiling the microscopic origins of quantum phases dominated by the interplay of spin and motional degrees of freedom constitutes one of the central challenges in strongly correla…
