    • Controlled Preparation and Detection of d-Wave Superfluidity in Two-Dimensional Optical Superlattices 

      Rey, A. M.; Sensarma, R.; Fölling, S.; Greiner, Markus; Demler, Eugene A.; Lukin, Mikhail D. (Institute of Physics, 2009)
      \(d\)-wave Cooper pairs are believed to be the key for understanding the phenomenon of high-temperature superconductivity in cuprates. These superconductors are an example of the emergence of strong pairing in systems with ...

    • Deterministic Coupling of a Single Nitrogen Vacancy Center to a Photonic Crystal Cavity 

      Englund, Dirk; Shields, Brendan John; Rivoire, Kelley; Hatami, Fariba; Vučković, Jelena; Park, Hongkun; Lukin, Mikhail D. (American Chemical Society, 2010)
      We describe and experimentally demonstrate a technique for deterministic, large coupling between a photonic crystal (PC) nanocavity and single photon emitters. The technique is based on in situ scanning of a PC cavity over ...

    • Inducing Vortices in a Bose-Einstein Condensate Using Holographically Produced Light Beams 

      Brachmann, Johannes; Bakr, Waseem; Gillen, Jonathon; Peng, Amy; Greiner, Markus (Optical Society of America, 2011)
      In this paper we demonstrate a technique that can create non-equilibrium vortex configurations with almost arbitrary charge and geometry in a Bose-Einstein condensate. We coherently transfer orbital angular momentum from ...

    • Magnetic Trapping of Atomic Nitrogen (\(^{14}\)N) and Cotrapping of NH (\(X\)\(^{3}\)\(\Sigma\) -) 

      Hummon, Matthew; Campbell, Wesley; Lu, Hsin-I; Tsikata, Edem; Wang, Yihua; Doyle, John M. (American Physical Society, 2008)
      We observe magnetic trapping of atomic nitrogen (\(^{14}\)N) and cotrapping of ground state imidogen (\(^{14}\)NH, \(X\)\(^{3}\)\(\Sigma\) -). Both are loaded directly from a room temperature beam via buffer gas cooling. ...

    • Theory of Cavity-Assisted Microwave Cooling of Polar Molecules 

      Wallquist, Margareta; Rabl, Peter; Lukin, Mikhail D.; Zoller, Peter (Institute of Physics, 2008)
      We analyze cavity-assisted cooling schemes for polar molecules in the microwave domain, where molecules are excited on a rotational transition and energy is dissipated via strong interactions with a lossy stripline cavity, ...

    • Time-Dependent Density-Functional Theory in Massively Parallel Computer Architectures: The Octopus Project 

      Andrade, Xavier; Alberdi-Rodriguez, Joseba; Strubbe, David A.; Oliveira, Micael J. T.; Nogueira, Fernando; Castro, Alberto; Muguerza, Javier; Arruabarrena, Agustin; Louie, Steven G.; Aspuru-Guzik, Alan; Rubio, Angel; Marques, Miguel A. L. (Institute of Physics, 2012)
      Octopus is a general-purpose density-functional theory (DFT) code, with a particular emphasis on the time-dependent version of DFT (TDDFT). In this paper we present the ongoing efforts to achieve the parallelization of ...

    • Time-Domain Measurement of Spontaneous Vibrational Decay of Magnetically Trapped NH 

      Campbell, Wesley; Groenenboom, Gerrit; Lu, Hsin-I; Tsikata, Edem; Doyle, John M. (American Physical Society, 2008)
      The \(v = 1 \to 0\) radiative lifetime of \(NH (X^3 \Sigma^-, v=1, N=0)\) is determined to be \(\tau_{rad,\text{exp.}} = 37.0 \pm 0.5_{\text{stat}}{}^{+2.0} _{-0.8\text{syst}}\) miliseconds, corresponding to a transition ...
