New Cell September, 2012
The third fabrication facility (fab3, dedicated to photonics) is completed. This, together with the lithography center (fab2) and the production hall (fab1), completes Ron's longtime effort to build a cutting edge fabrication facility at BGU. In the picture, Ron pointing out the planned location for the third clean room (September 2010).
New Cell July, 2012
The BEC2 experiment observes matter-wave fringes (interference pattern) after recombining a BEC which was split by a new field-gradient-beam-splitter on the atom chip. (S. Machluf et al, arXiv:1208.2526, published in Nature Communications)
New Cell January, 2012
Our BEC2 experiment observes interference fringes in a 1D BEC on an AtomChip.
These fringes are due to phase fluctuations when a BEC is extremely elongated.
New Cell November, 2011
New book edited by Ron is out: Quantum computing with neutral particles.
New Cell October, 2011
Rabi oscillations observed in room temperature solid matter (NV centers in Diamond).
Rabi oscillations, as well as Ramsey fringes, are a hall mark of quantum behavior and have been observed in our lab in three systems so far: cold atoms, vapor (room temperature gas) and solid state.
New Cell August, 2011

New Cell June, 2011
First homemade vapor cell gives nice spectroscopy
This is the first cell in Israel with paraffin coating. Our students from material engineering are studying different combinations of buffer gas and paraffin cell coating for enhanced coherence times. The eventual goal is to to understand and suppress dephasing in the vapor. In addition to new physics insights and applications such as quantum memory and magnetic sensors, such a cell will be miniaturized and manufactured inside the substrate of a semi-conductor chip for integrated devices.
