5 October 2019 - Open Day in Amsterdam
|
iqClock was present during the Sciene Park Open Day at the University of Amsterdam. Around 1000 visitors of all ages came to the Open Day; many visited the iqClock lab, followed a short lecture about clocks and timekeeping, and were able to see a magneto-optical trap (one of the key components of our optical atomic clocks) in action.

2 October 2019 - Girls' Day in Copenhagen
|
The Girls' Day at the Niels Bohr Institute in Copenhagen was a big success! Here iqClock's Stefan Alaric Schäffer is explaining how lenses work to our next generation of physicists.

30 September 2019 - A coated vacuum chamber
|
Optical atomic clocks require good vacuum chambers. One of the crucial aspects of these chambers is the coating. iqClock partner Acktar recently developed a coating for the vacuum chamber of one of our new ultra-precise clocks and made a nice video to present it.

15-20 September 2019 - Autumn School on Clocks, Cavities and Fundamental Physics
|
The iqClock Quantum Flagship consortium is pleased to announce the upcoming Autumn School on “Clocks, Cavities, and Fundamental Physics”, which will take place at the Institute of Physics, Nicolaus Copernicus University in Toruń, Poland, 15-20 September 2019.
The school welcomes students and postdocs from all over the world, and will focus on experiments and concepts that lie on the border of future optical atomic clocks, fundamental physics table-top experiments, and cosmology. Topics covered by the school include
Registration for the school is open until August 15, acceptance is on a rolling basis. The fee is EUR 200 and covers coffee breaks, lunches and the social program. Convenient accommodation can be booked through the conference secretary. Many choices for dinner are available at restaurants in downtown Toruń. For more information on the program, speakers, and registration, please see http://ccfp.pl/. We look forward to welcome you at the CCFP autumn school! |

28 August 2019 - PhD Stefan A. Schäffer
|
Congratulations to Stefan Alaric Schäffer (UCPH) for successfully defending his PhD thesis! In his work Stefan has investigated two approaches to cavity-enhanced clock operation using cold Strontium atoms – one based on cavity-enhanced spectroscopy, and one based on active lasing in the bad cavity regime, a forerunner for the superradiant lasers that will be built by the iqClock consortium. Additionally Stefan has taken part in the development of the Yb-clock at NIST, Boulder.
Stefan's thesis was titled Cavity-Enhanced Optical Clocks. In the picture, besides the proud laureate, are his supervisor Jan W. Thomsen and the committee consisting of Jérôme Lodewyck (LNE-SYRTE), Christain Lisdat (PTB), and Jörg H. Müller (NBI - UCPH). |

29 March 2019 - First iqClock preprint
The first iqClock-related preprint, Lasing on a narrow transition in a cold thermal strontium ensemble, was pre-published on the arXiv today. The authors are Stefan A. Schäffer, Mikkel Tang, Martin R. Henriksen, Asbjørn A. Jørgensen, Bjarke T. R. Christensen and Jan W. Thomsen (NBI Copenhagen). The paper was submitted to Physical Review A.
25 January 2019 - Video: iqClock - Building the most accurate clock in the world
|
During the annual Viva Fysica meeting for high school teachers and pupils in Amsterdam, Shayne Bennetts (UVA) gave a popular science talk iqClock: Building the most accurate clock in the world. The talk gives a nice overview of the methods and goals of the iqClock project. It can be watched on the UvA website by clicking here.
