Algorithms for determining resistances in quantum Hall annuli with p-n junctions
Chieh-I Liu, Dominick S. Scaletta, Dinesh K. Patel +4
Just a few of the promising applications of graphene Corbino pnJ devices include two-dimensional Dirac fermion microscopes, custom programmable quantized resistors, and mesoscopic…
Broadband Microwave Spectroscopy for Two-Dimensional Material Systems
Antonio Levy, Neil Zimmerman
In recent years, interesting materials have emerged which are only available as micron-scale flakes, and whose novel physics might be better understood through broadband microwave…
Algorithm for constructing customized quantized resistances in graphene junctions
Albert F. Rigosi, Martina Marzano, Antonio Levy +6
An algorithm is introduced for predicting quantized resistances in graphene p-n junction devices that utilize more than a single entry and exit point for electron flow. Depending o…
Optical evidence of the chiral magnetic anomaly in Weyl semimetal TaAs
Antonio L. Levy, Andrei B. Sushkov, Fengguang Liu +4
Chiral pumping from optical electric fields oscillating at THz frequencies is observed in the Weyl material TaAs with electric and magnetic fields aligned along both the a- and c-a…
Optical emission spectroscopy study of competing phases of electrons in the second Landau level
A. L. Levy, U. Wurstbauer, Y. Y. Kuznetsova +6
Quantum phases of electrons in the filling factor range are probed by the weak optical emission from the partially populated second Landau level and spin wave measu…
Gapped Excitations of unconventional FQHE states in the Second Landau Level
U. Wurstbauer, A. L. Levy, A. Pinczuk +5
We report the observation of low-lying collective charge and spin excitations in the second Landau level at ν = 2 + 1/3 and also for the very fragile states at ν = 2 + 2/5, 2 + 3/8…
