TL;DR: This work develops dynamical features of quantum memory-assisted entropic uncertainty relations (QMA-EUR) in a two-qubit Heisenberg XXZ spin chain with an inhomogeneous magnetic field and puts forward a possible physical interpretation to explain the evolutionary phenomenon of the uncertainty.

TL;DR: This work derives the dynamical evolution of the entropic uncertainty with respect to the measurement affecting by the canonical GAD noises when particle A is initially entangled with quantum memory B and presents a possible physical interpretation for the behavior of the uncertainty evolution by means of the mixedness of the observed system.

TL;DR: The relationship between the lower bound of the measured uncertainty and quantum coherence is investigated under a one-dimensional Heisenberg XXZ spin model with Dzyaloshinskii–Moriya (DM) interactions, and the effect of DM interaction on the entropic uncertainty is examined in details.

TL;DR: The structural, magnetic, electrical and dielectric properties of an Ir-based double perovskite compound, La2CoIrO6, have been investigated and it is shown that a clear magnetodielectric coupling effect exists in La2 coirO6 at low temperatures.

TL;DR: In this article, the development of S-band photocathode RF guns at Tsinghua University, with especial attention on the progress of guns developed after 2011, is explained.
