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…
Optical solitons in curved spacetime
Felix Spengler, Alessio Belenchia, Dennis Rätzel +1
Light propagation in curved spacetime is at the basis of some of the most stringent tests of Einstein's general relativity. At the same time, light propagation in media is at the b…
Influence of cosmological expansion in local experiments
Felix Spengler, Alessio Belenchia, Dennis Rätzel +1
Whether the cosmological expansion can influence the local dynamics, below the galaxy clusters scale, has been the subject of intense investigations in the past three decades. In t…
Perspectives of measuring gravitational effects of laser light and particle beams
Felix Spengler, Dennis Rätzel, Daniel Braun
We study possibilities of creation and detection of oscillating gravitational fields from lab-scale high energy, relativistic sources. The sources considered are high energy laser…
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…
