In the last decade, graphene has become an exciting platform for electron optical
experiments, in some aspects superior to conventional two-dimensional electron gases …

The dispersion of any given material is crucial for its charge carriers' dynamics. For all-
electronic, gate-defined cavities in gapped bilayer graphene, we developed a trajectory …

Ballistic, gate-defined devices in two-dimensional materials offer a platform for electron
optics phenomena influenced by the material's properties and gate control. We study the ray …

Recent results on electron tunneling across a potential barrier, inferred from observations or
obtained from theoretical models, have suggested superluminal or instantaneous barrier …

In sufficiently clean materials where electron-electron interactions are strong compared to
momentum-relaxing scattering processes, electron transport resembles the flow of a viscous …

We investigate relativistic wavepacket dynamics for an electron tunneling through a potential
barrier employing space-time resolved solutions to relativistic quantum field theory (QFT) …

We present the first experimental observation of quantized Klein tunneling in a bounded
Dirac system, implemented by a dimer chain of dielectric microwave resonators. Both the …

Klein tunneling is an old topic in relativistic quantum physics, and has been observed
recently in graphene where massless particles reside. Here, we propose a new …
