In a joint work of Anna Viatkina, Victor Flambaum and Amy Geddes, a single-particle relativistic formula found to estimate the isotope shift (IS) in many-electron atoms. It is used to predict the behavior of IS in superheavy atoms. They further analyse different contributions to the non-linearity of King plot arising from Standard Model. Their estimates […]

One of the results of the visit of Prof. Dmitri D. Ryutov to Mainz in the summer of 2017 is a paper (co-authored by Profs. D. Budker and V. V. Flambaum) on a possible influence of a finite mass of the photon on galactic rotation curves. The leading current explanation of the anomalous stellar velocities […]

We perform optical pumping of 87Rb atoms in a way that shows no power-broadening or light-shift effects. https://arxiv.org/abs/1708.08605

We have published a detailed description of an experiment we are conducting which will search for axion in yet-to-be explored parameter space. Best case scenario – we will find an axion. Otherwise we will set useful limits on axion’s mass and coupling strength. https://arxiv.org/abs/1707.05312

We propose a new method to measure parity non-conservation in molecules and conduct proof-of-principle experiment. link: https://arxiv.org/abs/1707.01759

A miniaturized cavity-enhanced room-temperature magnetic-field sensor based on nitrogen-vacancy centers was demonstrated by our group. The sensitivity and small size of the detector make it an ideal candidate for endoscopic magnetic field measurements aiming at biomedical applications. In contrast to most NV-based magnetometers the magnetic signal is extracted by observing infrared absorption of the NV […]

Prof. Dmitry Budker was awarded the following grants: A European Research Council (ERC) Advanced Grant of EUR 2.5 million to search for dark matter and dark energy. The funded project is entitled “Experimental Searches for Oscillating and Transient Effects from the Dark Sector”. Read the press release here. An EU-funded grant for the HORIZON 2020 […]

The Cosmic Axion Spin Precession Experiment (CASPEr), deserved a prize for being a breakthrough in physics.

First news post as test. More to come!
