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…
Reply to the comment on "Quantum priniple of relativity"
Andrzej Dragan, Artur Ekert
We refute criticisms by Del Santo and Horvat towards our paper "Quantum principle of relativity": most of their counterarguments can be dismissed, and the rest provides further evi…
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…
