Recording the birth and death of a single phonon

When light interacts with a crystal or a molecule, it can transfer energy to and from microscopic vibrations of their constituent atoms. The total energy is conserved, so that the difference in energy between the incoming and outgoing light equals the vibrational energy deposited in or recovered from the material. Physicists in Basel and Lausanne have developed a new technique to measure in real time the creation and destruction of individual quanta of vibrational energy (phonons) using ultra-short laser pulses and single photon detectors. They recorded the birth and death of single phonons in diamond and their technique can be applied to many different Raman active vibrational modes opening the way for detecting exotic vibrational quantum states such as entangled states where energy is delocalised over several vibrational modes. These results have been published in Physical Review Letters and selected as an Editor’s suggestion.

A Review on macroscopic quantum states appears in Rev. Mod. Phys. and makes the cover...

Quantum theory is by far our best description of the microscopic world. Surprisingly, there is nothing in the theory preventing macroscopic systems to be in quantum states. In principle, a cat could be dead and alive at the same time. A team of researchers around Nicolas Sangouard, in collaboration with colleagues from Innsbruck and Geneva, have written a review article presenting recent results on the difficulties and prospects of creating, maintaining, and detecting macroscopic quantum states. This review, which outlines the role of macroscopic quantum states in foundational questions as well as practical applications, has been published in the prestigious journal Reviews of Modern Physics and has been chosen for the cover of the next issue.

Individual impurity atoms detectable in graphene

A team including physicists from the University of Basel has succeeded in using atomic force microscopy to clearly obtain images of individual impurity atoms in graphene ribbons. Thanks to the forces measured in the graphene’s two-dimensional carbon lattice, they were able to identify boron and nitrogen for the first time, as the researchers report in the journal Science Advances.
