Non-linear media in weakly curved spacetime: optical solitons and probe pulses for gravimetry
Alessio Belenchia, Felix Spengler, Dennis Rätzel +1
That light propagating in a gravitational field gets frequency-shifted is one of the basic consequences of any metric theory of gravity rooted in the equivalence principle. At the…

Dynamical Quark Mass Generation in QCD\textsubscript{3} within the Hamiltonian approach in Coulomb gauge
Felix Spengler, Davide Campagnari, Hugo Reinhardt
We investigate the equal-time (static) quark propagator in Coulomb gauge within the Hamiltonian approach to QCD in spatial dimensions. Although the underlying Clifford algebr…

Branching of Center Vortices in SU(3) Lattice Gauge Theory
Felix Spengler, Markus Quandt, Hugo Reinhardt
We analyze the branching of center vortices in Yang-Mills theory in maximal center gauge. When properly normalized, we can define a branching probability that turns out to…
