Summary: Spin qubits associated with color centers show promise for various quantum technologies, but their intrinsic properties need to be known precisely under external conditions such as temperature and strain. This research develops a first-principles method to determine the temperature dependence of color centers' properties and demonstrates its accuracy with the NV-center in diamond. This method can be applied to different color centers and is useful for designing high-precision quantum sensors.

Summary: Artificial spin ice structures with different lattice symmetries (square, kagome, and triangle) exhibit reconfigurable microwave properties. The magnetization dynamics were investigated using ferromagnetic resonance spectroscopy. The results show distinct resonance modes in square spin ice structures, while kagome and triangular structures have well-separated modes localized at the center of individual nanomagnets. The orientation of nanomagnets with respect to the applied magnetic field leads to the merging and splitting of modes.

Summary: The use of heat transport interferometry can reveal anyonic statistics in charge insulators, even in the absence of charged excitations. By studying the heat transport through different interferometer geometries in Kitaev spin liquids, such as Fabry-Perot and Mach-Zehnder, drastically different behaviors can be observed, demonstrating the effectiveness of this method.

Summary: The passage introduces hydrodynamic spin lattices (HSLs) of 'walking' droplets as a class of active spin systems with particle-wave coupling, revealing various non-equilibrium symmetry-breaking phenomena that can be controlled by varying lattice geometry and system rotation. Theoretical predictions based on a generalized Kuramoto model rationalize experimental observations, establishing HSLs as a versatile platform for exploring active phase oscillator dynamics. The tunability of HSLs suggests exciting directions for future research, from active spin-wave dynamics to hydrodynamic analogue computation and droplet-based topological insulators.

Summary: We conducted measurements on the photoluminescence properties of single nitrogen-vacancy centers in diamond at various temperatures. We observed a significant reduction in PL intensity and spin contrast between 10K and 100K, which recovered to high levels at lower and higher temperatures. We also discovered a diverse dependence on magnetic bias field and crystal strain.

Summary: This study systematically investigates the temperature dependence of spin properties of divacancy defects in implanted 4H-SiC, providing possible theoretical explanations for the observed temperature-dependent dynamics. Samples implanted with different nitrogen molecule ion fluences show similar temperature-dependent behaviors, with the sample implanted with a lower ion fluence having longer coherence and depolarization times. This work promotes the understanding of spin properties in solid-state systems and their temperature dependence, which can be helpful for constructing wide temperature-range thermometers based on mature semiconductor materials.

Summary: Recent experimental advances in creating dissipative couplings provide a new route for engineering exotic lattice systems and exploring topological dissipation. Using a spatial lattice of atomic spin waves, we experimentally realize a dissipative version of the Su-Schrieffer-Heeger (SSH) model. The dissipative spectrum of the topological lattices shows edge modes within a dissipative gap. This work opens up the possibility of realizing non-Hermitian topological quantum optics through dissipative couplings.

Summary: In this paper, we present a generalization of the Luttinger-Tisza-Lyons-Kaplan theory to non-Bravais lattices, by adding Lagrange parameters to the diagonal of the Fourier transformed coupling matrix. We illustrate this approach with examples of modified honeycomb and square lattices, showing that it can obtain various types of ground states.

Summary: The study revealed that spin coherence in the native NV centers in high-purity bulk diamond is limited by spin-phonon interactions, with a maximum achievable coherence time of 6.8(2) ms at 295 K. The relaxation rate on specific transitions was found to be independent of NV concentration, indicating the dominant mechanism behind relaxation may be related to spin-phonon interactions. Future measurements of the temperature dependence of this relaxation rate are recommended.

Summary: Developing new techniques to search for particles beyond the standard model is crucial for understanding the ultraviolet completion of particle physics. This study demonstrates a search for spin-dependent interactions using a spin-based amplifier, establishing constraints and improving previous limits. The technique has the potential to be extended to investigate other exotic spin-dependent interactions.

Summary: This study theoretically investigates the spin-induced spin relaxation processes of divacancy qubits in 4H-SiC, revealing the dependence of the longitudinal spin relaxation time T-1 on the concentration of point defect spins and the applied magnetic field. The results demonstrate that dipolar spin relaxation plays a significant role in limiting the coherence time of divacancy qubits in both as-grown and ion-implanted samples.

Summary: The search for exotic long-range spin-spin velocity-dependent force using two iron shielded SmCo5 electron-spin sources and two optically pumped magnetometers has led to significant improvement in our understanding of physics beyond the standard model. By optimizing the orientations of the spin sources and magnetometers, we enhanced the exotic force and effectively subtracted common-mode noise. Our experiment set a direct limit on proton-electron interaction in a wide force range, with more than 10 orders of magnitude improvement compared to previous works.

Summary: Understanding the collective behavior of strongly correlated electrons in materials remains a central problem. A study on the relaxation dynamics of doubly occupied lattice sites in the three-dimensional DFHM revealed the emergence of a dynamical regime characterized by disorder-enhanced relaxation, which provides a theoretical framework for a previously inaccessible regime. The results demonstrate the ability of quantum simulators to enable understanding of complex many-body systems through minimal models.
