Journal Article
Mishchenko, A., Tu, J., Cao, Y., Gorbachev, R., Wallbank, J., Greenaway, M., …Novoselov, K. (2014). Twist-controlled resonant tunnelling in graphene/boron nitride/graphene heterostructures. Nature Nanotechnology, 9, 808-813. https://doi.org/10.1038/NNANO.2014.187

Recent developments in the technology of van der Waals heterostructures made from two-dimensional atomic crystals ave already led to the observation of new physical phenomena, such as the metal-insulator transition and Coulomb drag, and to the realis...

iSense: a technology platform for cold atom based quantum technologies (2014)
Conference Proceeding
Bongs, K., Malcolm, J., Ramelloo, C., Zhu, L., Boyer, V., Valenzuela, T., …Wicht, A. (2014). iSense: a technology platform for cold atom based quantum technologies. In Research in Optical Sciences. https://doi.org/10.1364/QIM.2014.QTu3B.1

A breakthrough in cold atom quantum technology is hindered by a bottleneck in the supporting technologies. We discuss a cold atom technology platform developed within the European iSense project, aiming at a gravimeter as demonstrator.

Subterahertz chaos generation by coupling a superlattice to a linear resonator (2014)
Journal Article
Hramov, A., Makarov, V., Koronovskii, A., Kurkin, S., Gaifullin, M., Alexeeva, N., …Balanov, A. (2014). Subterahertz chaos generation by coupling a superlattice to a linear resonator. Physical Review Letters, 112(116603), https://doi.org/10.1103/PhysRevLett.112.116603

We investigate the effects of a linear resonator on the high-frequency dynamics of electrons in devices exhibiting negative differential conductance. We show that the resonator strongly affects both the dc and ac transport characteristics of the devi...
