Dynamical time and Ashtekar variables for the Husain-Kuchař model

J. Fernando Barbero G., Juan Margalef-Bentabol, Aitor Vicente-Cano +1

The relation between the Husain-Kuchař model and some extensions thereof that incorporate a dynamical time variable is explored. To this end, we rely on the geometric approach to t…

Marginally Outer Trapped Tori in Black Hole Spacetimes

Kam To Billy Sievers, Liam Newhook, Sarah Muth +3

During a binary black hole merger, multiple intermediary marginally outer trapped tubes connect the initial pair of apparent horizons with the final (single) apparent horizon. The…

Ergodicity of the Spin-Boson Model for arbitrary coupling strength

Martin Koenenberg, Marco Merkli, Haifeng Song

We prove that the spin-boson system is ergodic, for arbitrary strengths of the coupling between the spin and the boson bath, provided the spin tunneling matrix element is small eno…
