  1. 15. Phase transitions, gravitational waves and the 2-Higgs doublet model
    Kari Rummukainen (University of Helsinki)
    6/6/23, 1:15 PM
  2. 3. Bubble nucleation and quantum initial conditions in classical statistical simulations
    Gerhard Ungersback (University of Stavanger)
    6/6/23, 1:45 PM

    Classical-statistical lattice simulations provide a useful approximation to out-of-equilibrium quantum field theory, but only for systems exhibiting large occupation numbers, and only for phenomena that are not intrinsically quantum mechanical in nature. In certain special circumstances, it can be appropriate to initialize such real-time simulations with quantum-like zero-point fluctuations....

  3. 1. Real scalar phase transitions: bubble nucleation, nonperturbatively
    Anna Kormu (University of Helsinki)
    6/6/23, 2:15 PM

    In the Standard Model the electroweak phase transition is a crossover, but in many beyond the Standard Model theories the transition is of first order. Strong first order PTs could produce gravitational waves that might be detectable by the Laser Interferometer Space Antenna (LISA). Perturbation theory is commonly used to estimate the parameters that enter the calculation of gravitational wave...

  4. 10. Lattice approaches to microphysical bubble dynamics
    Oliver Gould (University of Nottingham)
    6/6/23, 2:45 PM

    In the study of cosmological phase transitions, even apparently weakly coupled theories develop strongly coupled sectors. For static equilibrium quantities, lattice methods have been developed to tackle this which are able to yield unambiguously correct results up to small statistical errors. For real-time quantities, the problem is more complicated. In this talk, I will review approaches to...

  10. 2. Recent finite-volume developments in QED$_\textrm{L}$
    Nils Hermansson-Truedsson (Lund University/The University of Edinburgh)
    6/7/23, 1:45 PM

    In this talk I will briefly present our recent RBC/UKQCD result for isospin-breaking corrections to leptonic decay rates. With the leading systematic uncertainty coming from unknown finite-volume effects, I will discuss the analytical evaluation of these at order $1/L^3$. This order is particularly complicated in certain formulations of finite-volume QED, and requires better understanding for...
