My field of research is theoretical condensed matter physics. Since my PhD I have been working on different aspects of this wide research area, as summarised below. For further details, here you can find a complete list of my publications.

Graphene, Carbon nanotubes and NEMS:   The main focus of my research since few years are the electromechanical properties of graphene membranes and carbon nanotubes, and the quantum transport in nano-electromechanical systems (NEMS).

In this area I actively collaborate with the groups of Felix von Oppen (Freie Universitaet Berlin), Guillaume Weick (Strasbourg), Maura Sassetti (Genova) and Jari Kinaret (Chalmers).

Highlight papers in graphene and NEMS:

  • R. Leturcq, C. Stampfer, K. Inderbitzin, L. Durrer, C. Hierold, Eros Mariani, M.G. Schultz, F. von Oppen and K. Ensslin, "Franck-Condon blockade in suspended carbon nanotube quantum dots", Nature Physics 5, 327 - 331 (2009)
  • Eros Mariani and F. von Oppen, "Flexural phonons in free-standing graphene", Phys. Rev. Lett. 100, 076801 (2008)

Plasmonics and Polaritonics:   I recently started a new research project on cavity embedded metasurfaces. Here we showed how interactions between dipolar oscillators give rise to a polaritonic bandstructure that is tunable with the cavity width, with the emergence of chiral bosonic Dirac-like quasiparticles in 2D honeycomb arrays. 

In this area I collaborate with the groups of Bill Barnes (Exeter), Ortwin Hess (Imperial College) and Guillaume Weick and Rodolfo Jalabert (Strasbourg).

Highlight papers in plasmonics and polaritonics:

  • C-R. Mann, S.A.R. Horsley and Eros Mariani, "Tunable pseudo-magnetic fields for polaritons in strained metasurfaces", Nature Photonics 14, 669 (2020)
  • C-R. Mann, T.J. Sturges, G. Weick, W.L. Barnes and Eros Mariani, "Manipulating Type-I and Type-II Dirac Polaritons in Cavity-Embedded Honeycomb Metasurfaces", Nature Communications 9, 2194 (2018)

  • G. Weick, C. Woollacott, W. Barnes, O. Hess and Eros Mariani, "Dirac-like plasmons in honeycomb lattices of metallic nanoparticles", Phys. Rev. Lett. 110, 106801 (2013)

Quantum Hall Effects and Cold Atoms:   In the past years I also worked on cold atoms and on the fractional quantum Hall effects (Chern-Simons quantum field theory, composite fermions and non-abelian quantum Hall states).

Along this line, my main collaborations have been with the groups of Ady Stern (Weizmann Institute of Science), Felix von Oppen (Freie Universitaet Berlin), Rolf Haug (Hannover) and Maura Sassetti (Genova)
