Symplectic integration for the collisional gravitational $N$-body problem

Posted by klaurent MIT

Kavli Affiliate: Edmund Bertschinger | Summary:We present a new symplectic integrator designed for collisional gravitational $N$-body problems which makes use of Kepler solvers. The integrator is also reversible and conserves 9 integrals of motion of the $N$-body problem to machine precision. The integrator is second order, but the order can easily be increased by the […]

Macroscopic quantum resonators (MAQRO): 2015 Update

Posted by klaurent Caltech

Kavli Affiliate: Keith Schwab | Summary:Do the laws of quantum physics still hold for macroscopic objects – this is at the heart of Schrödinger’s cat paradox – or do gravitation or yet unknown effects set a limit for massive particles? What is the fundamental relation between quantum physics and gravity? Ground-based experiments addressing these questions […]
