How to identify a Majorana zero mode in an ultrafast way
Riku’s paper on ultrafast signatures of Majorana zero modes is online. Congrats! This was a very nice collaboration with our friends Enrico Perfetto and Gianluca Stefanucci in Rome as well as Robert van Leeuwen in Jyväskylä.
UXSS 2019 at CFEL Hamburg
Michael is organizing UXSS 2019, taking place in Hamburg, June 16-21, 2019. The ultrafast x-ray summer seminar (UXSS) is an annual school aimed at PhD students and junior postdocs working on or interested in learning about x-ray methods at free-electron laser sources. Topics range from basics of x-ray sources via atomic and molecular physics and chemical dynamics to structural biology and inelastic light scattering in correlated materials. Registration will open in early 2019.

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!
Fast computation of slow dynamics
Riku’s new paper on the adiabatic preparation of a correlated symmetry-broken initial state with the generalized Kadanoff-Baym ansatz is on arXiv.
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 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.
