Michael is a co-organizer of a minicolloquium on “Magnetism and Correlations in 2D Materials in and out of Equilibrium” at CMD2020GEFES in Madrid, August 31 – September 4, 2020. Featuring invited talks by Efrén Navarro-Moratalla, James McIver, Dante Kennes, and Ralph Ernstorfer.
The IMPRS-UFAST is looking for bright young minds willing to dive into research on ultrafast dynamics and imaging of matter. Application deadline is December 2nd, 2019.
For the Sentef group we are specifically looking for candidates in two areas of research:
If you are interested and would like to learn more, please do not hesitate to contact Michael.
Riku Tuovinen has been granted an Academy of Finland 3-year independent funding award starting in September 2019. In his project “Ultrafast many-body correlations in quantum transport and spectroscopy” Riku will develop and apply novel theoretical and computational methods for many-body quantum phenomena out of equilibrium. Congratulations, Riku!
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).
Riku’s new paper on the adiabatic preparation of a correlated symmetry-broken initial state with the generalized Kadanoff-Baym ansatz is on arXiv.
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.
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 mechanism is known in the engineering literature as AC-DC conversion or rectification. Here we investigated this mechanism in a quantum transport setup consisting of graphene nanoribbons, and derived some general “rules of thumb” for quantum pumping.
