Fermat's Principle in General Relativity via Herglotz Variational Formalism

Joanna Piwnik, Joanna Gonera, Piotr Kosiński

New form of Fermat's principle for light propagation in arbitrary (i.e. in general neither static nor stationary) gravitational field is proposed. It is based on Herglotz extension…

Note on the Margolus-Levitin quantum speed limit for arbitrary fidelity

Krzysztof Andrzejewski, Katarzyna Bolonek-Lasoń, Piotr Kosiński

For vanishing fidelity between initial and final states two important quantum speed limits, the Mandelstam-Tamm limit (involving energy dispersion) and Margolus-Levitin one (involv…
