Summary: In a certain parameter regime, a large cloud of confined Rb-87 atoms in a magneto-optical trap exhibits spatiotemporal instabilities resembling that of a turbulent fluid. We utilize turbulence theory and structure function analysis to extract scaling exponents and compare them to known turbulent regimes, allowing for clear distinction between different instability regimes.

Summary: Optical isolators are important for safeguarding laser diodes from damage caused by reflected light, and achieving high-density integration with conventional methods has been challenging. However, the use of mu-transfer printing of a Ce:YIG/SGGG coupon has allowed for the experimental demonstration of a compact MO isolator based on a Mach-Zehnder interferometer with Si waveguides. This isolator has a small footprint, a thickness of approximately 1 μm, and achieved a maximum isolation ratio of 14 dB in telecom bands.

Summary: Operating magneto-optic coupled ring isolators near an exceptional point can enhance isolation bandwidth by making it depend on the square root of nonreciprocal phase shift, leading to over 50% increase in bandwidth at a specific insertion loss for a given pair of rings.

Summary: The study reveals the magneto-optical Kerr effect (MOKE) induced by the formation of magnetic skyrmions in Gd2PdSi3, referred to as topological MOKE. The presence of skyrmions leads to a significant enhancement of the optical rotation, exemplifying the light-skyrmion interaction arising from the emergent gauge field. The findings pave the way for photonic technology based on skyrmionics.

Summary: The study demonstrates how a ferrimagnetic sphere resonator made of yttrium iron garnet can function as a polarization-selective optical modulator in the telecom band. It shows that the input state of polarization contributing to each sideband is orthogonal, leading to nearly orthogonal polarizations between the sidebands and incident light in single sideband modulation. Additionally, it suggests utilizing intermodulation gain in the nonlinear regime for amplification.

Summary: We propose a scheme for loading dysprosium atoms into a narrow-line three-dimensional magneto-optical trap (3D MOT) using a two-dimensional MOT on the broad 421-nm line to generate a high-flux slow atoms beam. Efficient loading of the 3D MOT is achieved even without the push beam, and further enhancement is observed by adding push beams at either 421 nm or 626 nm. The best performance is achieved with a red-detuned push beam on the 626-nm line, resulting in an enhancement factor of 3.6.

Summary: In this study, slotted all-dielectric nanodisks made of amorphous silicon (a-Si) with double-well optical potentials are demonstrated for stable trapping of small dielectric nanoparticles. The use of infrared wavelengths with no optical loss for a-Si allows trapping without heating the surrounding environment. Numerical results show successful trapping of one to two nanoparticles, regardless of their morphology, using this all-dielectric nanostructure.

Summary: Germanatetellurite glasses doped with dysprosium at different concentrations were studied for their luminescence characteristics and temperature-dependent absorption using optical spectroscopy techniques. The findings revealed that the efficiency of dysprosium excitation decreases at higher temperatures and demonstrated the presence of effective dysprosium interactions in the studied glasses.

Summary: Melt quenching was used to prepare Dy3+ ion doped alkaline borophosphate glasses in this research. The XANES measurement confirmed that Dy ions in glass were in the +3 oxidation state. The glasses showed absorption peaks corresponding to transitions from the ground state 6H15/2 to higher energy levels of Dy3+ ion, and luminescence spectra exhibited four prominent emission bands.

Summary: In this work, a confocal-cavity-QED microscope is used to achieve cooperativity exceeding 110, which is comparable to the best single-mode cavities. This is made possible by the dispersive coupling to the atoms of many near-degenerate modes in the cavity, providing important insights for studying quantum many-body physics in the driven-dissipative setting.

Summary: We investigate the impact of tunable integrability-breaking dipole-dipole interactions on the equilibrium states of 1D Bose gases of dysprosium at low temperatures. Our experimental results show that in the strongly correlated Tonks-Girardeau regime, rapidity and momentum distributions are unaffected by the dipolar interactions. However, significant changes occur when the strength of the contact interactions is decreased. We propose a model that captures the main experimental observations by considering the system as an array of 1D gases with only contact interactions, dressed by the contribution of the short-range part of the dipolar interactions.
