Photothermal effects in ultra-precisely stabilized tunable microcavities
Johannes F. S. Brachmann, Hanno Kaupp, Theodor W. Hänsch +1
We study the mechanical stability of a tunable high-finesse microcavity under ambient conditions and investigate light-induced effects that can both suppress and excite mechanical…
Calibrating an interferometric laser frequency stabilization to MHz precision
Johannes F. S. Brachmann, Thomas Kinder, Kai Dieckmann
We report on a calibration procedure that enhances the precision of an interferometer based frequency stabilization by several orders of magnitude. For this purpose the frequency d…
Inducing vortices in a Bose-Einstein condensate using holographically produced light beams
Johannes F. S. Brachmann, Waseem S. Bakr, Jonathon Gillen +2
In this paper we demonstrate a technique that can create out-of-equilibrium vortex configurations with almost arbitrary charge and geometry in a Bose-Einstein condensate. We cohere…
Current Status of Quark Gluon Plasma Signals
D. Zschiesche, S. Bass, M. Bleicher +9
Compelling evidence for the creation of a new form of matter has been claimed to be found in Pb+Pb collisions at SPS. We discuss the uniqueness of often proposed experimental signa…
Hydrodynamic Models for Heavy-Ion Collisions, and beyond
A. Dumitru, J. Brachmann, E. S. Fraga +5
A generic property of a first-order phase transition in equilibrium, and in the limit of large entropy per unit of conserved charge, is the smallness of the isentropic speed of sou…
Observing compact quark matter droplets in relativistic nuclear collisions
K. Paech, J. Brachmann, M. A. Lisa +3
Compactness is introduced as a new method to search for the onset of the quark matter transition in relativistic heavy ion collisions. That transition supposedly leads to stronger…
