Celestial mechanics of elastic bodies
Robert Beig, Bernd G. Schmidt
We construct time independent configurations of two gravitating elastic bodies. These configurations either correspond to the two bodies moving in a circular orbit around their cen…
Helically symmetric N-particle solutions in scalar gravity
Robert Beig, J. Mark Heinzle, Bernd G. Schmidt
Within a scalar model theory of gravity, where the interaction between particles is given by the half-retarded + half-advanced solution of the scalar wave equation, we consider an…
Static self-gravitating elastic bodies in Einstein gravity
Lars Andersson, Robert Beig, Bernd Schmidt
We prove that given a stress-free elastic body there exists, for sufficiently small values of the gravitational constant, a unique static solution of the Einstein equations coupled…
Quantum liquid of repulsively bound pairs of particles in a lattice
David Petrosyan, Bernd Schmidt, James R. Anglin +1
Repulsively interacting particles in a periodic potential can form bound composite objects, whose dissociation is suppressed by a band gap. Nearly pure samples of such repulsively…
Exact numerical simulations of a one-dimensional, trapped Bose gas
Bernd Schmidt, Michael Fleischhauer
We analyze the ground-state and low-temperature properties of a one-dimensional Bose gas in a harmonic trapping potential using the numerical density matrix renormalization group.…
How to bypass Birkhoff through extra dimensions (a simple framework for investigating the gravitational collapse in vacuum)
Piotr Bizoń, Bernd G. Schmidt
It is fair to say that our current mathematical understanding of the dynamics of gravitational collapse to a black hole is limited to the spherically symmetric situation and, in fa…
