Imaging reconfigurable molecular concentration on a graphene field-effect transistor

Kavli Affiliate: Michael F. Crommie | First 5 Authors: Franklin Liou, Hsin-Zon Tsai, Andrew S. Aikawa, Kyler C. Natividad, Eric Tang | Summary: The spatial arrangement of adsorbates deposited onto a clean surface in vacuum typically cannot be reversibly tuned. Here we use scanning tunneling microscopy to demonstrate that molecules deposited onto graphene field-effect transistors […]

Topological quantum interference in a pumped Su-Schrieffer-Heeger lattice

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Zeng-Zhao Li, Juan Atalaya, K. Birgitta Whaley, , | Summary: Topological quantum interference emerges from the interplay between quantum mechanics and topology. We present evidence for two types of such interference phenomenon that can result from the quantum dynamics of initial topological states. We realize both […]

Note: Nonuniqueness of generalized quantum master equations for a single observable

Kavli Affiliate: David T. Limmer | First 5 Authors: Nathan Ng, David T. Limmer, Eran Rabani, , | Summary: When deriving exact generalized master equations for the evolution of a reduced set of degrees of freedom, one is free to choose what quantities are relevant by specifying projection operators. However, obtaining a reduced description does […]

Demonstration of universal control between non-interacting qubits using the Quantum Zeno effect

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: Eliya Blumenthal, Chen Mor, Asaf A. Diringer, Leigh S. Martin, Philippe Lewalle | Summary: The Zeno effect occurs in quantum systems when a very strong measurement is applied, which can alter the dynamics in non-trivial ways. Despite being dissipative, the dynamics stay coherent within any degenerate […]
