    • Characterization of Topological States on a Lattice with Chern Number 

      Hafezi, Mohammad; Sørensen, Anders; Lukin, Mikhail D.; Demler, Eugene A. (Institute of Physics, 2008)
      We study Chern numbers to characterize the ground state of strongly interacting systems on a lattice. This method allows us to perform a numerical characterization of bosonic fractional quantum Hall (FQH) states on a lattice ...

    • Coherent Quantum Optical Control with Subwavelength Resolution 

      Gorshkov, Alexey Vyacheslavovich; Jiang, Liang; Greiner, Markus; Zoller, Peter; Lukin, Mikhail D. (American Physical Society, 2008)
      We suggest a new method for quantum optical control with nanoscale resolution. Our method allows for coherent far-field manipulation of individual quantum systems with spatial selectivity that is not limited by the wavelength ...

    • Nuclear Spin Cooling Using Overhauser-Field Selective Coherent Population Trapping 

      Issler, Mena; Kessler, Eric M.; Giedke, Geza; Yelin, Susanne; Cirac, Ignacio; Lukin, Mikhail D.; Imamoglu, Atac (American Physical Society, 2010)
      We show that a quantum interference effect in optical absorption from two electronic spin states of a solid-state emitter can be used to prepare the surrounding environment of nuclear spins in well-defined states, thereby ...

    • On the Chemical Bonding Effects in the Raman Response: Benzenethiol Adsorbed on Silver Clusters 

      Saikin, Semion K.; Olivares-Amaya, Roberto; Rappoport, Dmitrij; Stopa, Michael; Aspuru-Guzik, Alán (Royal Society of Chemistry, 2009)
      We study the effects of chemical bonding on Raman scattering from benzenethiol chemisorbed on silver clusters using time-dependent density functional theory (TDDFT). Raman scattering cross sections are computed using a ...

    • Robust Optical Delay Lines with Topological Protection 

      Hafezi, Mohammad; Demler, Eugene A.; Lukin, Mikhail D.; Taylor, Jacob Mason (Nature Publishing Group, 2011)
      Phenomena associated with the topological properties of physical systems can be naturally robust against perturbations. This robustness is exemplified by quantized conductance and edge state transport in the quantum Hall ...
