Description
In honour of this year’s Nobel Prize recognition of Donna Strickland for her work on chirped-pulse amplification, we will celebrate the impact her work and highlight some current frontiers of optical science.
En l’honneur du Prix Nobel décerné à Donna Strickland pour son travail sur l’amplification d'impulsions par dérive de fréquence, nous célébrerons l’impact de son travail et soulignerons quelques initiatives aux frontières de la science optique.
We present a study that uses a technique extending upon high harmonic spectroscopy, which is generated as a function of photoexcitation pump fluence to probe the resulting ultrafast dynamics of the insulator-to-metal phase transition in VO2 [1]. When heated to above ~343 K, VO2 experience a complete atomic rearrangement of the crystal lattice structure from a monoclinic insulator (M1 phase)...
Quantum materials exhibit a range of astonishing phenomena that embody the central scientific questions currently challenging condensed matter physics. Within these systems, ultrashort light pulses can create controlled non-equilibrium electronic conditions to reveal physical properties not accessible at equilibrium. Beyond uncovering the interaction mechanisms between electrons, lattice, and...
State of the art atomic sensors operate near the standard quantum limit (SQL) of projection noise, where the precision scales as the square root of the particle number. Overcoming this limit by using atom-atom entanglement such as spin squeezing is a major goal in quantum metrology. Spin squeezing can be realized by coupling an atomic ensemble to a high-finesse optical resonator, where the...
The ALPHA (Antihydrogen Laser PHysics Apparatus) Collaboration at CERN is engaged in precision tests of fundamental symmetries between matter and antimatter. A primary goal is to study the optical spectroscopy of antihydrogen, the bound state of an antiproton and positron. Recent progress in the synthesis and confinement of antihydrogen has resulted in the availability for spectroscopy of a...
