    Mou, Zong-Gang; Saffin, Paul M.; Tranberg, Anders (Peer reviewed; Journal article, 2021-02)
    We perform large-scale real-time simulations of a bubble wall sweeping through an out-of-equilibrium plasma. The scenario we have in mind is the electroweak phase transition, which may be first order in extensions of the ...

    Delgado Gaspar, Ismael; Sussman, Roberto A.; McNutt, David Duncan; Coley, Alan (Peer reviewed; Journal article, 2021-04)
    In two recently published articles, Barrow and Paliathanasis (2018, 2019) [1, 2] claim to have found exact solutions of Einstein’s field equations belonging to the class of non-trivial (i.e., spatially inhomogeneous) ...
  • An Invariant Characterization of the Levi-Civita Spacetimes 

    Watson, Cooper; Julius, William; Gorban, Matthew; McNutt, David Duncan; Davis, Eric; Cleaver, Gerald (Peer reviewed; Journal article, 2021-08)
    In the years 1917–1919 Tullio Levi-Civita published a number of papers presenting new solutions to Einstein’s equations. This work, while partially translated, remains largely inaccessible to English speaking researchers. ...
  • Correlated insulators in twisted bilayer graphene 

    Mandal, Ipsita; Yao, Jia; Mueller, Erich J. (Peer reviewed; Journal article, 2021-03)
    Experiments on graphene bilayers, where the top layer is rotated with respect to the one below, have displayed insulating behavior when the moiré bands are partially filled. We calculate the charge distributions in these ...
  • Importance Sampling-based Transport Map Hamiltonian Monte Carlo for Bayesian Hierarchical Models 

    Osmundsen, Kjartan Kloster; Kleppe, Tore Selland; Liesenfeld, Roman (Peer reviewed; Journal article, 2021-06)
    We propose an importance sampling (IS)-based transport map Hamiltonian Monte Carlo procedure for performing a Bayesian analysis in nonlinear high-dimensional hierarchical models. Using IS techniques to construct a transport ...
  • Derivations of the Young-Laplace equation 

    Siqveland, Leiv Magne; Skjæveland, Svein Magne (Journal article, 2021-04)
    The classical Young-Laplace equation relates capillary pressure to surface tension and the principal radii of curvature of the interface between two immiscible fluids. In this paper the required properties of space curves ...

    Faber, T.; Liu, Y.; Porod, W.; Hudec, M.; Malinsky, M.; Staub, F.; Kolesova, Helena (Peer reviewed; Journal article, 2020-05)
    We demonstrate that in a recently proposed unified leptoquark model based on the gauge group SU(4)C×SU(2)L×U(1) R significant deviations from the Standard Model values of R K and R K ∗ can be accommodated without any need ...
  • Matching the Nonequilibrium Initial Stage of Heavy Ion Collisions to Hydrodynamics with QCD Kinetic Theory 

    Kurkela, Aleksi; Mazeliauskas, Aleksas; Paquet, Jean-Francois; Schlichting, Sören; Teaney, Derek (Peer reviewed; Journal article, 2019-03)
    High-energy nuclear collisions produce a nonequilibrium plasma of quarks and gluons which thermalizes and exhibits hydrodynamic flow. There are currently no practical frameworks to connect the early particle production in ...
  • Improved Gauss law model and in-medium heavy quarkonium at finite density and velocity 

    Lafferty, David; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2020-03)
    We explore the in-medium properties of heavy-quarkonium states at finite baryochemical potential and finite transverse momentum based on a modern complex-valued potential model. Our starting point is a novel, rigorous ...
  • Transmission in pseudospin-1 and pseudospin-3/2 semimetals with linear dispersion through scalar and vector potential barriers 

    Mandal, Ipsita (Peer reviewed; Journal article, 2020-09)
    We investigate the tunneling of pseudospin-1 and pseudospin-3/2 quasiparticles through a barrier consisting of both electrostatic and vector potentials, existing uniformly in a finite region along the transmission axis. ...
  • Highly occupied gauge theories in 2+1 dimensions: A self-similar attractor 

    Boguslavski, K; Kurkela, Aleksi; Lappi, T; Peuron, J (Peer reviewed; Journal article, 2019-11)

  • Bottomonium suppression at RHIC and LHC 

    Krouppa, Brandon; Rothkopf, Alexander Karl; Strickland, Michael (Peer reviewed; Journal article, 2019-02)
    The strong suppression of heavy quarkonia is a good indicator that one has generated a quark-gluon plasma (QGP) in an ultrarelativistic heavy ion collision. Recent advancements in first principles calculations of the heavy ...

    Astrakhantsev, Nikita Yu.; Bornyakov, Vitaly G.; Braguta, Victor V.; Ilgenfritz, Ernst-Michael; Kotov, Andrey Yuryevich; Nikolaev, Alexander A.; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2019-05)

    Kurkela, Aleksi; Wiedemann, Urs Achim (Peer reviewed; Journal article, 2019-09)
    How physical systems approach hydrodynamic behavior is governed by the decay of nonhydrodynamic modes. Here, we start from a relativistic kinetic theory that encodes relaxation mechanisms governed by different timescales ...

    Hervik, Sigbjørn; Ortaggio, Marcello (Peer reviewed; Journal article, 2020-10)
    We explore how far one can go in constructing d-dimensional static black holes coupled to p-form and scalar fields before actually specifying the gravity and electrodynamics theory one wants to solve. At the same time, we ...
