A corner reflector of graphene Dirac fermions as a phonon-scattering sensor
H. Graef, Q. Wilmart, M. Rosticher +10
Dirac fermion optics exploits the refraction of chiral fermions across optics-inspired Klein-tunneling barriers defined by high-transparency p-n junctions. We consider the corner r…
Ultra-long wavelength Dirac plasmons in graphene capacitors
H. Graef, D. Mele, M. Rosticher +8
Graphene is a valuable 2D platform for plasmonics as illustrated in recent THz and mid-infrared optics experiments. These high-energy plasmons however, couple to the dielectric sur…
Landau velocity for collective quantum Hall breakdown in bilayer graphene
W. Yang, H. Graef, X. Lu +12
Breakdown of the quantum Hall effect (QHE) is commonly associated with an electric field approaching the inter Landau-level (LL) Zener field, ratio of the Landau gap and cyclotron…
Comment on ''Exceptional points and double poles of the S matrix''
C. Dembowski, B. Dietz, H. -D. Graef +4
In a recent paper [Phys. Rev. E 67, 026204 (2003)], Rotter calculates the geometric phases that are picked up by the eigenvectors of a two-state quantum system when an exceptional…
Latest Developments from the S-DALINAC*
M. Brunken, H. Genz, M. Gopych +15
The S-DALINAC is a 130 MeV superconducting recirculating electron accelerator serving several nuclear and radiation physics experiments as well as driving an infrared free-electron…
Wave Dynamical Chaos in Superconducting Microwave Cavities
H. Rehfeld, H. Alt, C. Dembowski +4
During the last few years we have studied the chaotic behavior of special Euclidian geometries, so-called billiards, from the quantum or in more general sense "wave dynamical" poin…
