Berry phase jumps and giant nonreciprocity in Dirac quantum dots
Joaquin F. Rodriguez-Nieva, Leonid S. Levitov
We predict that a strong nonreciprocity in the resonance spectra of Dirac quantum dots can be induced by the Berry phase. The nonreciprocity arises in relatively weak magnetic fiel…
Resonant Tunneling and Intrinsic Bistability in Twisted Graphene Structures
Joaquin F. Rodriguez-Nieva, Mildred S. Dresselhaus, Leonid S. Levitov
We predict that vertical transport in heterostructures formed by twisted graphene layers can exhibit a unique bistability mechanism. Intrinsically bistable - characteristics…
Creating and Probing Electron Whispering Gallery Modes in Graphene
Yue Zhao, Jonathan Wyrick, Fabian D. Natterer +7
Designing high-finesse resonant cavities for electronic waves faces challenges due to short electron coherence lengths in solids. Previous approaches, e.g. the seminal nanometer-si…
Enhanced thermionic-dominated photoresponse in graphene Schottky junctions
Joaquin F. Rodriguez-Nieva, Mildred S. Dresselhaus, Justin C. W. Song
Vertical heterostructures of van der Waals materials enable new pathways to tune charge and energy transport characteristics in nanoscale systems. We propose that graphene Schottky…
Is the apparent period-doubling in Blazhko stars actually an illusion?
Paul H. Bryant
The light curves of many Blazhko stars exhibit intervals in which successive pulsation maxima alternate between two levels in a way that is characteristic of period-doubling. In ad…
