Detection of quantum entanglement across the event horizon
Patryk Michalski, Andrzej Dragan
We investigate the problem of distinguishing between separable and entangled states of two quantum wave packets, one of which falls into a black hole. Intuitively, one might expect…
Reply to 'Comment on "Ideal clocks -- a convenient fiction"'
Krzysztof Lorek, Jorma Louko, Andrzej Dragan
For a quantum scalar field that is confined in a uniformly linearly accelerated cavity in Minkowski spacetime and interacts linearly with a scalar field that is not confined in the…
Higgs-like field interactions before symmetry breaking
Jerzy Paczos, Szymon Cedrowski, Krzysztof TurzyÅski +1
We investigate the Brout-Englert-Higgs mechanism of spontaneous symmetry breaking and show that, before symmetry breaking, the interaction of Higgs fields with massless gauge field…
Stories in the two-state vector formalism
Patryk Michalski, Andrzej Dragan
The two-state vector formalism of quantum mechanics is a time-symmetrized approach to standard quantum theory. In our work, we aim to establish rigorous foundations for the future…
Gravitationally Induced Entanglement Between Particles in Harmonic Traps: Limits for Gaussian States
Julia Tokarska, Andrzej Dragan
Gravitationally induced entanglement has been proposed as a probe of the quantum nature of gravity. This work analyzes a system of two particles in harmonic traps interacting only…
The relativistic reason for quantum probability amplitudes
Karol Sajnok, Kacper DÄbski, Kacper Dębski +1
We show that the quantum-mechanical probability distribution involving complex probability amplitudes can be derived from three natural conditions imposed on a relativistically inv…
