Out-of-plane dielectric susceptibility of graphene in twistronic and Bernal bilayers

Sergey Slizovskiy, Aitor Garcia-Ruiz, Alexey I. Berdyugin +6

We describe how the out-of-plane dielectric polarizability of monolayer graphene influences the electrostatics of bilayer graphene -- both Bernal (BLG) and twisted (tBLG). We compa…

Detection of quantum interference without interference

Iliya Esin, Alessandro Romito, Yuval Gefen

Quantum interference is typically detected through the dependence of the interference signal on certain parameters (path length, Aharonov-Bohm flux, etc.), which can be varied in a…

Frequency stabilization and noise-induced spectral narrowing in resonators with zero dispersion

L. Huang, S. M. Soskin, I. A. Khovanov +3

Mechanical resonators are widely used as precision clocks and sensitive detectors that rely on the stability of their eigenfrequencies. The phase noise is determined by different f…

Nonreciprocal response theory of nonhermitian mechanical metamaterials: response phase transition from the skin effect of zero modes

Henning Schomerus

Nonreciprocal nonhermitian systems provide an unconventional localization mechanism of topological zero modes via the nonhermitian skin effect. While fundamental theoretical charac…

Synthetic dimensions and topological chiral currents in mesoscopic rings

Hannah M. Price, Tomoki Ozawa, Henning Schomerus

The recently-introduced concept of "synthetic dimensions" allows for the realization of higher-dimensional topological phenomena in lower-dimensional systems. In this work we study…

Nonlocal Spin Transport as a Probe of Viscous Magnon Fluids

Camilo Ulloa, A. Tomadin, J. Shan +3

Magnons in ferromagnets behave as a viscous fluid over a length scale, the momentum-relaxation length, below which momentum-conserving scattering processes dominate. We show theore…
