Measuring Phonon Dispersion and Electron-Phason Coupling in Twisted Bilayer Graphene with a Cryogenic Quantum Twisting Microscope
John Birkbeck, Jiewen Xiao, Alon Inbar +7
The coupling between electrons and phonons is one of the fundamental interactions in solids, underpinning a wide range of phenomena such as resistivity, heat conductivity, and supe…
Hunting for Majoranas
Ali Yazdani, Felix von Oppen, Bertrand I. Halperin +1
Over the last decade, there have been considerable efforts to observe non-abelian quasi-particles in novel quantum materials and devices. These efforts are motivated by the goals o…
Elastic theory of quantum Hall smectics: effects of disorder
Stefan Scheidl, Felix von Oppen
We study the effect of disorder on quantum Hall smectics within the framework of an elastic theory. Based on a renormalization group calculation, we derive detailed results for the…
The half-filled Landau level - composite fermions and dipoles
Felix von Oppen, Bertrand I. Halperin, Steven H. Simon +1
The composite-fermion approach as formulated in the fermion Chern-Simons theory has been very successful in describing the physics of the lowest Landau level near Landau level fill…
General Localization Lengths for Two Interacting Particles in a Disordered Chain
Pil Hun Song, Felix von Oppen
The propagation of an interacting particle pair in a disordered chain is characterized by a set of localization lengths which we define. The localization lengths are computed by a…
Composite Fermions in Modulated Structures: Transport and Surface Acoustic Waves
Felix von Oppen, Ady Stern, Bertrand I. Halperin
Motivated by a recent experiment of Willett et al. [Phys. Rev. Lett. 78, 4478 (1997)], we employ semiclassical composite-fermion theory to study the effect of a periodic density mo…
Current noise, electron-electron interactions, and quantum interference
Felix von Oppen, Ady Stern
It is shown that electron-electron interactions lead to a novel quantum-interference contribution to non-equilibrium current noise in mesoscopic conductors. The corresponding noise…
Semiclassical theory of transport in antidot lattices
Gregor Hackenbroich, Felix von Oppen
We present a detailed study of quantum transport in large antidot arrays whose classical dynamics is chaotic. We calculate the longitudinal and Hall conduc- tivities semiclassicall…
