    Li, Shiyong; Yee, Ho-Ung (American Physical Society, 2018-09)
    We compute the dynamical relaxation times for chiral transport phenomena in a strongly coupled regime using the AdS/CFT correspondence. These relaxation times can be a useful proxy for the dynamical timescale for achieving ...

    Cheung, K.; Keung, W. Y.; Tseng, P. Y.; Yuan, T. C. (Elsevier, 2015-12-17)
    Recently, the ATLAS Collaboration recorded an interesting anomaly in diboson production with excesses at the diboson invariant mass around 2 TeV in boosted jets of all the WZ, W+W-, and ZZ channels. We offer a theoretical ...

  • New class of planar ferroelectric Mott insulators via first-principles design 

    Kim, C.; Park, H.; Marianetti, C. A. (American Physical Society, 2015-12-11)
    The bulk photovoltaic effect requires a low electronic band gap (i.e., ≈1-2 eV) and large electronic polarization, which is not common in known materials. Here we use first-principles calculations to design layered double ...

    Cahill-Rowley, M.; Hewett, J. L.; Ismail, A.; Rizzo, T. G. (American Physical Society, 2015-10-21)
    We demonstrate that the 3σ excess observed by ATLAS in the Z+MET channel can be explained within the context of the MSSM. Using the freedom inherent in the pMSSM, we perform a detailed analysis of the parameter space and ...

    Ling, B; Stephanov, MA (American Physical Society, 2016-03-28)
    We argue that a crucial determinant of the acceptance dependence of fluctuation measures in heavy-ion collisions is the range of correlations in the momentum space, e.g., in rapidity, ycorr. The value of ycorr ∼ 1 for ...
