Observation of Majorana Quantum Critical Behavior in a Resonant Level Coupled to a Dissipative Environment
H. T. Mebrahtu, I. V. Borzenets, H. Zheng +5
We investigate experimentally an exotic state of electronic matter obtained by fine-tuning to a quantum critical point (QCP), realized in a spin-polarized resonant level coupled to…
Quantum Phase Transition in a Resonant Level Coupled to Interacting Leads
Henok T. Mebrahtu, Ivan V. Borzenets, Dong E. Liu +5
An interacting one-dimensional electron system, the Luttinger liquid, is distinct from the "conventional" Fermi liquids formed by interacting electrons in two and three dimensions.…
Pb-graphene-Pb Josephson junctions: characterization in B field
I. V. Borzenets, U. C. Coskun, H. Mebrahtu +1
We fabricate superconductor-graphene-superconductor Josephson junctions with superconducting regions made of lead (Pb). The critical current through grapehene may be modulated by e…
Resonant Tunneling in a Dissipative Environment
Yu. Bomze, H. Mebrahtu, I. Borzenets +2
We measure tunneling through a single quantum level in a carbon nanotube quantum dot connected to resistive metal leads. For the electrons tunneling to/from the nanotube, the leads…
