CORPES 2019 at Oxford

CORPES 2019 (international workshop on strong correlations and angle-resolved photoemission spectroscopy) is taking place at Worcester College, Oxford (UK), July 15-19, 2019. Click here for the line-up of invited speakers.

Paper published in Science Advances

Our paper on cavity materials – how to manipulate matter with pure vacuum fluctuations of light – was published in Science Advances. Here is the press release.

Gabriel’s paper in Nature Communications

Gabriel’s paper is out in Nature Communications: G. E. Topp et al., Nature Communications 9, 4452 (2018). Here is a link to the press release “Shedding light on Weyl fermions” on the MPSD website (click here for a German version). Congratulations, Gabriel!

Cavity superconductivity

Our paper on cavity QED superconductivity is online: arXiv:1802.09437. We propose to use the coupling of matter to quantized photon modes inside a cavity to enhance electron-phonon coupling and influence superconductivity.

Charge pumping in graphene

Riku’s paper with Mike Ridley on charge pumping in ac-driven graphene nanoribbons has been published in Physical Review B. Congrats! Popular summary: Typically, electronic current flowing through a conductor needs a net voltage to be applied across the conductor. However, applying an alternating voltage, which is zero on average, may induce a direct current. This… Continue reading Charge pumping in graphene

How to make a material more correlated with light

Our preprint “Light-enhanced electron-phonon coupling from nonlinear electron-phonon coupling” is available on arXiv. In this work, it is shown how one can amplify electron-lattice coupling by using lasers that are tuned to a phonon, that is coupled quadratically to the electrons of the material. Such enhanced electron-lattice coupling can lead to the formation of polarons… Continue reading How to make a material more correlated with light
