    • Anomaly-Induced Inhomogeneous Phase in Quark Matter without the Sign Problem 

      Brauner, Tomas; Filios, Georgios; Kolesova, Helena (Peer reviewed; Journal article, 2019)
      We demonstrate the existence of an anomaly-induced inhomogeneous phase in a class of vectorlike gauge theories without the sign problem, thus disproving the long-standing conjecture that the absence of the sign problem ...

    • Chemical equilibration in hadronic collisions 

      Kurkela, Aleksi; Mazeliauskas, Aleksas (Peer reviewed; Journal article, 2019)
      We study chemical equilibration in out-of-equilibrium quark-gluon plasma using the first principles method of QCD effective kinetic theory, accurate at weak coupling. In longitudinally expanding systems—relevant for ...

    • Discovering Partonic Rescattering in Light Nucleus Collisions 

      Huss, Alexander; Kurkela, Eero Aleksi; Mazeliauskas, Aleksas; Paatelainen, Risto; van der Schee, Wilke; Wiedemann, Urs Achim (Peer reviewed; Journal article, 2021-05)
      We demonstrate that oxygen-oxygen collisions at the LHC provide unprecedented sensitivity to parton energy loss in a system whose size is comparable to those created in very peripheral heavy-ion collisions. With leading ...

    • Early- and Late-Time Behavior of Attractors in Heavy-Ion Collisions 

      Kurkela, Aleksi; van der Schee, Wilke; Wiedemann, Urs Achim; Wu, Bin (Peer reviewed; Journal article, 2020)
      Whether, how, and to what extent solutions of Bjorken-expanding systems become insensitive to aspects of their initial conditions is of importance for heavy-ion collisions. Here we study 1+1D and phenomenologically relevant ...

    • Fractional Soft Limits of Scattering Amplitudes 

      Brauner, Tomas; Esposito, Angelo; Penco, Riccardo (Peer reviewed; Journal article, 2022)
      It is a common lore that the amplitude for a scattering process involving one soft Nambu-Goldstone boson should scale like an integer power of the soft momentum. We revisit this expectation by considering the 2 → 2 scattering ...

    • 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 ...

    • Multimode Quasinormal Spectrum from a Perturbed Black Hole 

      Capano, Collin D.; Cabero, Miriam; Westerweck, Julian; Abedi, Jahed; Kastha, Shilpa; Nitz, Alexander H.; Wang, Yi-Fan; Nielsen, Alex Bentley; Krishnan, Badri (Peer reviewed; Journal article, 2023)
      When two black holes merge, the late stage of gravitational wave emission is a superposition of exponentially damped sinusoids. According to the black hole no-hair theorem, this ringdown spectrum depends only on the mass ...

    • Nonequilibrium attractor in high-temperature QCD plasmas 

      Almaalol, Dekrayat; Kurkela, Aleksi; Strickland, Michael (Peer reviewed; Journal article, 2020)
      We establish the existence of a far-from-equilibrium attractor in weakly coupled gauge theory undergoing one-dimensional Bjorken expansion. We demonstrate that the resulting far-from-equilibrium evolution is insensitive ...

    • Nonperturbative analysis of the electroweak phase transition in the two Higgs doublet model 

      Andersen, Jens Oluf; Gorda, Tyler; Helset, Andreas; Niemi, Lauri; Tenkanen, Tuomas V.I.; Tranberg, Anders; Vuorinen, Aleksi; Weir, David J. (Journal article; Peer reviewed, 2018-11)
      We perform a nonperturbative study of the electroweak phase transition (EWPT) in the two Higgs doublet model (2HDM) by deriving a dimensionally reduced high-temperature effective theory for the model, and matching to known ...

    • Soft Interactions in Cold Quark Matter 

      Gorda, Tyler; Kurkela, Eero Aleksi; Paatelainen, Risto; Säppi, Saga; Vuorinen, Aleksi (Peer reviewed; Journal article, 2021-10)
      Accurate knowledge of the thermodynamic properties of zero-temperature, high-density quark matter plays an integral role in attempts to constrain the behavior of the dense QCD matter found inside neutron-star cores, ...
