A self-trapped Bose-Einstein condensate is shown to be stabilized in
two-dimensional free space by Rabi oscillations between two hyperfine states
which make an effective interatomic interaction oscillate in time. The

In 1955 George Mackey suggested that there is a fundamental dichotomy in the

arxiv_dataset-182708.0349 | Observational Constraints on Agegraphic Dark Energy
astro-ph
In this paper, we use the Type Ia supernova data as well as the CMB and LSS

arxiv_dataset-183708.0449 | Unitary Solution to a Quantum Gravity Information Paradox
quant-ph gr-qc
We consider a toy model of the interaction of a qubit with an exotic
space-time containing a time-like curve. Consistency seems to require that the
global evolution of the qubit be non-unitary. Given that quantum mechanics is
globally unitary,... | arxiv topic:quant-ph gr-qc |
