The case of Quantum Gravity with Spontaneous Collapse of the Wave Function
Lajos Diósi
When about half a century ago the concept of universal spontaneous collapse of the wave function was conceived it was an attempt to alter standard non-relativistic quantum physics.…

Hybrid completely positive Markovian quantum-classical dynamics
Lajos Diósi
A concise and self-contained derivation of hybrid quantum-classical dynamics is given in terms of Markovian master equations. Many previously known results are re-derived, revised,…

On the linear friction many-body equation for dissipative spontaneous wavefunction collapse
Giovanni Di Bartolomeo, Matteo Carlesso, Kristian Piscicchia +3
We construct and study the simplest universal dissipative Lindblad master equation for many-body systems with the purpose of a new dissipative extension of existing nonrelativistic…
