The Accelerated UniverseThe universe has gone through two phases of accelerated expansion: a primordial phase called cosmic inflation and an ongoing phase that has been taking place for the last 6 billions years.To explore cosmic inflation, we are now on the hunt for the primordial cosmic microwave background (CMB) B-modes. This signal ...
Physics achaeology: unearthing a 45 year old quantum spin liquidI will introduce the topic of quantum spin liquid as a prime example of emergent behavior in strongly interacting system. Recently a new example, 1T-TaS2 has been discovered. Surprisingly this material has been thoroughly studied for 45 years as a charge density wave material but its spin liquid property has ...

Free lunches with chips and coherent beams: from Ramsey fringes to integrated circuit inspectionInterference between coherent photon pulses separated in time yields the famous Ramsey fringes, which allow the dynamics of objects exposed to the pulses to be characterized with much greater precision than suggested by the Heisenberg uncertainty relation applied to the pulse bandwidth. The same applies for coherent photon beams separated ...
The ALPHA Collaboration at CERN has combined antiprotons and positrons to create and probe antihydrogen atoms. ALPHA can now store over 1000 antihydrogen atoms at a time for thousands of seconds. We have developed techniques to conduct precision physics using minimal numbers of antiatoms. The comparison of antihydrogen and hydrogen ...

People and Robots SeminarBefore learning robots can be deployed in the real world, it is critical that probabilistic guarantees can be made about the safety and performance of such systems. In recent years, so-called "high-confidence" reinforcement learning algorithms have enjoyed success in application areas with high-quality models and plentiful data, but robotics remains ...
Hunting Dark Matter at Collider ExperimentsDark matter is believed to make up most of the matter of our Universe, but its particle origin remains a mystery. So far experimental searches for dark matter particles have largely focused on the mass window at around the Hoggs boson mass. At the same time, lighter dark matter candidates ...
Climate models suggest that keeping to within a 2° future will require us to remove excess carbon dioxide from the atmosphere. A common prediction is that we will need to be removing ten billion tons (gigatons) of CO2 per year from the air in 2050 and continue for the foreseeable ...
