      Generation of monoenergetic ion bunch from a double-layer thin-foil target irradiated by an intense linearly polarized laser pulse is investigated using two-dimensional particle-in-cell simulation. The protons in the front ...
    • Accessing Rydberg-dressed interactions using many-body Ramsey dynamics 

      Mukherjee, Rick; Killian, Thomas C.; Hazzard, Kaden R.A. (2016)
      We demonstrate that Ramsey spectroscopy can be used to observe Rydberg-dressed interactions in a many-body system well within experimentally measured lifetimes, in contrast to previous research, which either focused on ...
    • Actinide chemistry using singlet-paired coupled cluster and its combinations with density functionals 

      Garza, Alejandro J.; Alencar, Ana G. Sousa; Scuseria, Gustavo E. (2016)
      Singlet-paired coupled cluster doubles (CCD0) is a simplification of CCD that relinquishes a fraction of dynamic correlation in order to be able to describe static correlation. Combinations of CCD0 with density functionals ...
    • Active quantum plasmonics 

      Marinica, Dana Codruta; Zapata, Mario; Nordlander, Peter; Kazansky, Andrey K.; Echenique, Pedro M.; Aizpurua, Javier; Borisov, Andrei G. (2015)
      The ability of localized surface plasmons to squeeze light and engineer nanoscale electromagnetic fields through electron-photon coupling at dimensions below the wavelength has turned plasmonics into a driving tool in a ...
    • Adiabatic cooling of atoms by an intense standing wave 

      Chen, Jian; Story, J.G.; Tollett, J.J.; Hulet, Randall G. (1992)
      Lithium atoms channeled in the nodes of an intense standing-wave radiation field are cooled to near the recoil limit by adibatically reducing the radiation intensity. The final momentum distribution has a narrow component ...
    • Aging, Jamming, and the Limits of Stability of Amorphous Solids 

      Lubchenko, Vassiliy; Wolynes, Peter G. (2018)
      Apart from not having crystallized, supercooled liquids can be considered as being properly equilibrated and thus can be described by a few thermodynamic control variables. In contrast, glasses and other amorphous solids ...
    • Alignment of the CMS tracker with LHC and cosmic ray data 

      Adair, A.; Akgun, B.; Ecklund, K.M.; Geurts, F.J.M.; Li, W.; Michlin, B.; Padley, B.P.; Redjimi, R.; Roberts, J.; Zabel, J. (2014)
