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…
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…
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…
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…
Decoherence due to the Casimir effect?
Anirudh Gundhi
Open system dynamics of an electron is studied in the presence of radiation field, confined between two parallel conducting pates. It has been suggested in previous works that the…
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…
Motion of an electron through vacuum fluctuations
Anirudh Gundhi, Angelo Bassi
We study the effects of the electromagnetic vacuum on the motion of a nonrelativistic electron. First, we derive the equation of motion for the expectation value of the electron's…
Impact of dynamical collapse models on inflationary cosmology
Anirudh Gundhi, José Luis Gaona-Reyes, Matteo Carlesso +1
Inflation solves several cosmological problems at the classical and quantum level, with a strong agreement between the theoretical predictions of well-motivated inflationary models…
Scalaron-Higgs inflation reloaded: Higgs-dependent scalaron mass and primordial black hole dark matter
Anirudh Gundhi, Christian F. Steinwachs
We propose an extension of the scalaron-Higgs model by a non-minimal coupling of the Standard Model Higgs boson to the quadratic Ricci scalar resulting in a Higgs-dependent scalaro…
Primordial black hole dark matter in dilaton-extended two-field Starobinsky inflation
Anirudh Gundhi, Sergei V. Ketov, Christian F. Steinwachs
We investigate the production of primordial black holes and their contribution to the presently observed dark matter in a dilaton two-field extension of Starobinsky's quadratic $f(…
Scalaron-Higgs inflation
Anirudh Gundhi, Christian F. Steinwachs
In scalaron-Higgs inflation the Standard Model Higgs boson is non-minimally coupled to gravity and the Einstein-Hilbert action is supplemented by the quadratic scalar curvature inv…
