Dynamics of spinning particles in pp-wave spacetimes
K. Andrzejewski
In this work, we study the dynamics of a spinning particle in pp-wave spacetimes; in particular, plane gravitational waves and impulsive shockwaves. We present a step-by-step proce…
Group-theoretical analysis of quantum complexity: the oscillator group case
K. Andrzejewski, K. Bolonek-Lasoń, P. Kosiński
Motivated by the recent rapid development of complexity theory applied to quantum mechanical processes we present the complete derivation of Nielsen's complexity of unitaries belon…
The area and volume laws for entanglement of scalar fields in flat and cosmological spacetimes
K. Andrzejewski
We study the area and volume laws for entanglement of free quantum scalar fields. In addition to the entropy, we use the notion of the capacity of entanglement, which measures entr…
Revisiting the dynamics of a charged spinning body in curved spacetime
K. Andrzejewski
We analyse the motion of the spinning body (in the pole-dipole approximation) in the gravitational and electromagnetic fields described by the Mathisson-Papapetrou-Dixon-Souriau eq…
Evolution of capacity of entanglement and modular entropy in harmonic chains and scalar fields
K. Andrzejewski
We examine the temporal evolution of the modular entropy and capacity (in particular, the fluctuation of the entanglement entropy) for systems of time-dependent oscillators coupled…
