Title: Speed of evolution in entangled fermionic systems
Authors: Sahory Canseco J. and Andrea Vald\'es-Hern\'andez
Abstract summary: We consider the simplest identical-fermion system that exhibits the phenomenon of entanglement (beyond exchange correlations) A characterization of the quantum speed limit and the orthogonality times is performed, throwing light into the general structure of the faster and the slower states. It is shown that the connection between speed of evolution and entanglement in the fermionic system, though more subtle than in composites of distinguishable parties, may indeed manifest for certain classes of states.

Abstract: We consider the simplest identical-fermion system that exhibits the phenomenon of entanglement (beyond exchange correlations) to analyze its speed of evolution towards an orthogonal state, and revisit the relation between this latter and the amount of fermionic entanglement. A characterization of the quantum speed limit and the orthogonality times is performed, throwing light into the general structure of the faster and the slower states. Such characterization holds not only for fermionic composites, but apply more generally to a wide family of 6-dimensional states, irrespective of the specific nature of the system. Further, it is shown that the connection between speed of evolution and entanglement in the fermionic system, though more subtle than in composites of distinguishable parties, may indeed manifest for certain classes of states.

Non-coherent evolution of closed weakly interacting system leads to equidistribution of probabilities of microstates [0.0]
We show that for weakly interacting systems such evolution is a Markovian process. We search for time dependence of mean numbers of particles in single-particle states and find that under made assumptions it is governed by Boltzmann integral collision. In this theory, the non-coherence is the mechanism that transforms time-reversible unitary evolution into time-irreversible evolution.

A magnetic clock for a harmonic oscillator [89.99666725996975]
We study how the quantum dynamics transforms into a classical-like behaviour when conditions related with macroscopicity are met by the clock alone. In the description of this emerging behaviour finds its place the classical notion of time, as well as that of phase-space and trajectories on it.

Exact universal bounds on quantum dynamics and fast scrambling [0.0]
We show that the spectral form factor sets a universal state-independent bound on the quantum dynamics of a complete set of initial states over arbitrarily long times. We use this result to constrain the scrambling of information in interacting many-body systems.

Exotic correlation spread in free-fermionic states with initial patterns [0.0]
We describe a relation between the light-cone velocities after a quantum quench and the internal structure of the initial state. We find that the observed velocities range from zero to the Fermi velocity and may not always be obtained from the dispersion relation for valid momenta.

Optimal bounds on the speed of subspace evolution [77.34726150561087]
In contrast to the basic Mandelstam-Tamm inequality, we are concerned with a subspace subject to the Schroedinger evolution. By using the concept of maximal angle between subspaces we derive optimal bounds on the speed of such a subspace evolution. These bounds may be viewed as further generalizations of the Mandelstam-Tamm inequality.

Quantum speed limits for time evolution of a system subspace [77.34726150561087]
In the present work, we are concerned not with a single state but with a whole (possibly infinite-dimensional) subspace of the system states that are subject to the Schroedinger evolution. We derive an optimal estimate on the speed of such a subspace evolution that may be viewed as a natural generalization of the Fleming bound.
