The Faculty of Physics cordially invites all interested individuals to another lecture in the ISQI series. This time, Dr Andrzej Dragan from Warsaw University will present the 'Covariant quantum field theory of tachyons'.
The event will take place on 9 November at 15:00.
Abstract:
Three major misconceptions concerning quantized tachyon fields: the energy spectrum unbounded from below, the frame-dependent and unstable vacuum state, and the non-covariant commutation rules, are shown to be a result of misrepresenting the Lorentz group in a too small Hilbert space. By doubling this space we establish an explicitly covariant framework that allows for the proper quantization of the tachyon fields eliminating all of these issues. Our scheme that is derived to maintain the relativistic covariance also singles out the two-state formalism developed by Aharonov et al. [1] as a preferred interpretation of the quantum theory.
