The relativistic reason for quantum probability amplitudes
Karol Sajnok, Kacper Dębski, Andrzej Dragan
We show that the quantum-mechanical probability distribution involving complex probability amplitudes can be derived from three natural conditions imposed on a relativistically inv…
Covariant quantum field theory of tachyons
Jerzy Paczos, Kacper Dębski, Szymon Cedrowski +4
Three major misconceptions concerning quantized tachyon fields: the energy spectrum unbounded from below, the frame-dependent and unstable vacuum state, and the non-covariant commu…
Universality of quantum time dilation
Kacper Dębski, Piotr T. Grochowski, Rafał Demkowicz-Dobrzański +1
Time dilation is a difference in measured time between two clocks that either move with different velocities or experience different gravitational potentials. Both of these effects…
Relativity of superluminal observers in spacetime
Andrzej Dragan, Kacper Dębski, Szymon Charzyński +2
We develop an extension of special relativity in dimensional spacetime to account for superluminal inertial observers and show that such an extension rules out the convention…
Indefinite temporal order without gravity
Kacper Dębski, Magdalena Zych, Fabio Costa +1
According to the general theory of relativity, time can flow at different rates depending on the configuration of massive objects, affecting the temporal order of events. Recent re…
Quantum time dilation in a gravitational field
Jerzy Paczos, Kacper Dębski, Piotr T. Grochowski +2
According to relativity, the reading of an ideal clock is interpreted as the elapsed proper time along its classical trajectory through spacetime. In contrast, quantum theory allow…
Effect of relativistic acceleration on tripartite entanglement in Gaussian states
Jan A. Szypulski, Piotr T. Grochowski, Kacper Dębski +1
Efficiencies of quantum information protocols can be affected by the noninertial motion of involved parties, e.g., in a gravitational field. Most of the previous studies focused on…
Casimir effect in conformally flat spacetimes
Bartosz Markowicz, Kacper Dębski, Maciej Kolanowski +2
We discuss several approaches to determine the Casimir force in inertial frames of reference in different dimensions. On an example of a simple model involving mirrors in Rindler s…
Quantum time dilation in atomic spectra
Piotr T. Grochowski, Alexander R. H. Smith, Andrzej Dragan +1
Quantum time dilation occurs when a clock moves in a superposition of relativistic momentum wave packets. We utilize the lifetime of an excited hydrogen-like atom as a clock to dem…
