Master equation for systems interacting with linearized gravity
Oliviero Angeli, Anirudh Gundhi, Angelo Bassi
We investigate the open quantum dynamics of a system of two masses interacting with an environment of linearized gravitational waves. We formulate the analysis in terms of the obse…
Towards relativistic generalization of collapse models
Anirudh Gundhi, Lajos Diósi, Matteo Carlesso
Spontaneous collapse models provide a possible, testable solution to the quantum measurement problem. While experiments are providing increasingly stronger bounds on their paramete…
Can classical theories of gravity produce entanglement?
Anirudh Gundhi, Giorgia Infantino, Angelo Bassi
A recent paper published in Nature [Nature,646,813(2025)] claims that quantum particles become entangled through their gravitational interaction, even when the gravitational potent…
From equivalent Lagrangians to inequivalent open quantum system dynamics
Anirudh Gundhi, Oliviero Angeli, Angelo Bassi
Lagrangians can differ by a total derivative without altering the equations of motion, thus encoding the same physics. This is true both classically and quantum mechanically. We sh…
Measuring Decoherence Due to Quantum Vacuum Fluctuations
Anirudh Gundhi, Hendrik Ulbricht
The interaction of a particle with vacuum fluctuations--which theoretically exist even in the complete absence of matter--can lead to observable irreversible decoherence if it were…
