Riku receives Academy of Finland funding

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!

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
