I and i
TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.

Advances in Magnetics Roadmap on Spin-Wave Computing
TL;DR: Magnonics addresses the physical properties of spin waves and utilizes them for data processing as mentioned in this paper , and many proof-of-concept prototypes have already been realized in laboratories, such as the one presented in this article.

Split spin-squeezed Bose-Einstein Condensates
TL;DR: In this article, the authors investigated the behavior of split spin-squeezed Bose-Einstein condensates (BECs) and analyzed the system's entanglement properties.

Basis-independent quantum coherence and its distribution
TL;DR: In this paper, a basis-independent formulation of quantum coherence is proposed, which is related to the purity of system rather than the superposition in a particular basis, where the maximally mixed state is used as the reference state, which allows for a way of defining coherence that is invariant under arbitrary unitary transformations.

Observation of Bose-Einstein Condensation in a Dilute Atomic Vapor
TL;DR: A Bose-Einstein condensate was produced in a vapor of rubidium-87 atoms that was confined by magnetic fields and evaporatively cooled and exhibited a nonthermal, anisotropic velocity distribution expected of the minimum-energy quantum state of the magnetic trap in contrast to the isotropic, thermal velocity distribution observed in the broad uncondensed fraction.
Bose-Einstein condensation in dilute gases
TL;DR: In this paper, a unified introduction to the physics of ultracold atomic Bose and Fermi gases for advanced undergraduate and graduate students, as well as experimentalists and theorists is provided.
