Massive quantum systems as interfaces of quantum mechanics and gravity
The traditional view from particle physics is that quantum gravity effects should only become
detectable at extremely high energies and small length scales. Due to the significant …

Non-inertial quantum clock frames lead to non-Hermitian dynamics
The operational approach to time is a cornerstone of relativistic theories, as evidenced by
the notion of proper time. In standard quantum mechanics, however, time is an external …
