Kirigami/Origami Metasurfaces for Controlling Electromagnetic Waves

Kirigami and origami provide versatile spatial deformations in the design of reconfigurable metasurfaces, leading to various applications in deployable devices. In article number 2400213, Yilin Zheng, Ke Chen, and Yijun Feng provide an overview highlighting the implementations of kirigami/origami metasurfaces and their applications in controlling electromagnetic waves.

Negative-Mass Black Holes under Antichronous Transformations

Black hole's gravitational singularities are solved by interior negative energies and masses through time transformations of relativistic quantum mechanics and antichronous transformations of the full Lorentz group, which, if taking place at event horizons, respect Einstein's equivalence principle. For further details, see article number 2400139 by Manuel Uruena Palomo.

Enhancement of Quantum Entanglement in Cavity–Magnon systems

In article number 2400221, Rong-Can Yang, Hong-Yu Liu, and co-workers focus on the enhancement of quantum entanglement and quantum steering in cavity–magnon hybrid systems using quantum coherent feedback (QCFB) control loops, as shown in the cover image. In the scheme, SQUID is applied to realize Josephson parametric amplification, driving the 3D microwave cavity with two-photon field. Moreover, quantum correlation of the two magnon modes is indirectly established through the magnetic dipole interaction, and the enhancement is implemented effectively with QCFB.

With the help of the Annalen der Physik, we can trace the young Einstein's footsteps in Italy in various ways: the interest in the topic of his first article on capillarity probably dates back to an earlier meeting with Carlo Marangoni in Casteggio; Einstein's reading of articles by Paul Drude and Wilhelm Wien allow us to identify the library of the Lombard Institute, Milan's Academy of Sciences and Letters, where the young man is working on his bibliography; this bibliography provides elements for a better understanding of the turnaround of his thesis, in mid-April 1901, on molecular forces in gases; and finally we see Einstein use his papers in the Annalen in his search for university posts, in connection with Giuseppe Jung, Michele Besso's uncle.

The paper introduces the concept of interferometric quantum teleportation. Based on this concept, a quantum secure communication (QSC) protocol, operating in a single-photon regime is proposed. The proposed protocol is characterized with higher efficiency and data rate than its original counterpart, namely, the teleportation-based quantum secure communication (T-QSC). The proposal is verified to be secure. Its security relies on both quantum (polarization of qubits) and relativistic (speed of light) restrictions. The relativistic restriction is possible due to the use of an interferometric quantum channel, like the relativistic quantum key distribution.

Self-Organizing Trivalent Spin Network

Spin dynamics in a Loop Quantum Gravity model with self-organized criticality leads to avalanches. Employing ergodic concepts, a perimeter–entropy relation is derived for the dimensionally reduced black hole. This entropy originates from the excitation–relaxation spin dynamics during avalanche cycles. For further details, see article number 2400109 by Christine C. Dantas.
