The spheromak tilting and how it affects modelling coronal mass ejections
Eleanna Asvestari, Tobias Rindlisbacher, Jens Pomoell +1
Spheromak type flux ropes are increasingly used for modelling coronal mass ejections (CMEs). Many models aim in accurately reconstructing the magnetic field topology of CMEs, consi…
SU(2) gauge theory with quarks at non-zero mass
Jarno Rantaharju, Tobias Rindlisbacher, Kari Rummukainen +2
We study SU(2) gauge field theory with quarks. The theory is asymptotically non-free and, at vanishing quark mass, governed by a Gaussian fixed point at long distances. On…
Bulk-preventing actions for SU(N) gauge theories
Tobias Rindlisbacher, Kari Rummukainen, Ahmed Salami
We introduce a one-parameter family of SU(N) gauge actions which, when used in combination with an HMC update algorithm, prevent the gauge system from entering an artificial bulk-"…
Non-perturbative decoupling of massive fermions
Tobias Rindlisbacher, Kari Rummukainen, Ahmed Salami +1
SU(2) gauge theory with Nf=24 massless fermions is non-interacting at long distances, i.e. it has an infrared fixed point at vanishing coupling. With massive fermions the fermions…
Spectrum of SU(2) gauge theory at large number of flavors
Jarno Rantaharju, Tobias Rindlisbacher, Kari Rummukainen +2
We present a numerical study of the spectrum of an asymptotically non-free gauge theory with massive fermion flavors. For such large number of flavors, asymptotic…
