Seeded bubble nucleation on the lattice
Simone Blasi, Andreas Ekstedt, Jaakko Hällfors +1
We provide the first non-perturbative lattice determination of the bubble nucleation rate as seeded by topological defects during a first order phase transition. Our case of study…
Lattice study of the critical bubble in deconfinement transition
Kari Rummukainen, Riikka Seppä, David J. Weir
Strongly coupled theories are of phenomenological interest, for example as dark matter candidates. Theories that can undergo first order thermal phase transitions are particularly…
Confined-deconfined interface tension and latent heat in SU(N) gauge theory
Tobias Rindlisbacher, Kari Rummukainen, Ahmed Salami
We present high-precision lattice results for the confined-deconfined interface tension and the latent heat of pure SU() gauge theories up to and investigate their asympt…
The confined-deconfined surface tension in SU(N) gauge theories at large N
Tobias Rindlisbacher, Kari Rummukainen, Ahmed Salami
We present results from an investigation of the -dependency of the confined-deconfined interface tension and latent heat in pure SU() gauge theory at large . The interface…
Improved Dirichlet boundary conditions for lattice gauge-fermion theories
Tobias Rindlisbacher, Kari Rummukainen, Ahmed Salami
Hybrid Monte Carlo (HMC) simulations of lattice gauge theories with fermionic matter rely on the invertibility of the lattice Dirac operator. Near-zero modes of the latter can ther…
The Standard Model cross-over on the lattice
Michela D'Onofrio, Kari Rummukainen
With the physical Higgs mass the Standard Model symmetry restoration phase transition is a smooth cross-over. We study the thermodynamics of the cross-over using numerical lattice…
Investigating the Sharpe-Singleton scenario on the lattice by direct eigenvalue computation
Joni M. Suorsa, T. Rantalaiho, K. Rummukainen +2
We investigate the phase structure of lattice QCD with dynamical Wilson fermions. Wilson chiral perturbation theory predicts that the Aoki phase and the Sharpe-Singleton scenario m…
Perturbative Improvement of the Schrodinger Functional for Lattice Strong Dynamics
T. Karavirta, K. Rummukainen, K. Tuominen
Lattice simulations on SU(2) and SU(3) gauge theories with matter fields in the fundamental, adjoint and two index symmetric representations are needed to determine if these theori…
Hard Thermal Loops and the Sphaleron Rate on the Lattice
D. Bodeker, G. D. Moore, K. Rummukainen
We measure the sphaleron rate (topological susceptibility) of hot SU(2) gauge theory, using a lattice implementation of the hard thermal loop (HTL) effective action. The HTL degree…
Finite T Electroweak Phase Transition on the Lattice
K. Rummukainen
This talk reviews recent lattice results on the high electroweak phase transition. A remarkably accurate picture emerges: a) the transition is of first order for $m_H \lsim 80$…
Interface Tension in Quenched QCD
Y. Iwasaki, K. Kanaya, Leo Kärkkäinen +2
We calculate the tension of the interface between the confined and deconfined phases by the histogram method in SU(3) lattice gauge theory for temporal extents of 4 and 6 using…
Computing Masses from Effective Transfer Matrices
M. Hasenbusch, K. Pinn, K. Rummukainen
We study the use of effective transfer matrices for the numerical computation of masses (or correlation lengths) in lattice spin models. The effective transfer matrix has a strongl…
Multicanonical Cluster Algorithm
K. Rummukainen
In this talk I present a multicanonical hybrid-like two-step algorithm, which consists of a microcanonical spin system update with demons, and a multicanonical demon refresh. The d…
Multicanonical Cluster Algorithm and the 2-D 7-State Potts Model
K. Rummukainen
I present a hybrid-like two-step algorithm, which combines a microcanonical update of a spin system using demons, with a multicanonical demon refresh. The algorithm is free from th…
