Summary: The elastocaloric effect (ECE) measures changes in entropy related to strain experienced by a material, providing valuable information about the entropy landscape near strain-tuned phase transitions. By combining ECE measurements with elastoresistivity measurements, a direct comparison of thermodynamic and transport properties can be made, revealing unexpected relationships between doping dependence and scattering intensity of low-energy quasi-particles by nematic fluctuations.

Summary: In this paper, Cs-133 nuclear magnetic resonance (NMR) measurements were used to study the magnetic properties of an A-type antiferromagnet CsCo2Se2. The results showed evidence of antiferromagnetic transition at 70 K, with increasing antiferromagnetic spin fluctuations at lower temperatures. The linear relationship between T1T-T indicated that antiferromagnetic spin fluctuations are two-dimensional in the paramagnetic state.

Summary: We propose a technique for polarizing and cooling finite many-body classical systems using feedback control. The fluctuations of non-conserved degrees of freedom are converted into the growth of a conserved one. Numerical simulations of classical spin systems validate the proposal.

Summary: We have studied the local structure of La0.5-xNa0.5+xFe2As2 superconductor and found a significant change in the structure around the arsenic atom with hole doping. The As-Fe bond becomes stronger with hole doping, while the axial As-Asa bond tends to weaken in the optimally doped regime. These results suggest the importance of electron-lattice coupling and axial As atom displacements in the superconductivity of these iron-based materials.

Summary: We investigate the possibility of using magnetic Josephson junctions as magnetic noise detectors. By considering a system of a quantum dot coupled to superconducting leads in the presence of an external magnetic field, we relate the noise in the Josephson current to magnetization noise under appropriate assumptions. At the 0-pi transition point driven by a magnetic field, the sensitivity of the junction as a magnetic noise detector is greatly enhanced and diverges at zero temperature. Furthermore, we demonstrate that, if fluctuations also affect the energy of the quantum dot, only the magnetic noise channel contributes to the Josephson current noise response when the quantum dot is in resonance with the superconducting leads.

Summary: In this study, time-of-flight inelastic neutron scattering (INS) was used to investigate the spin fluctuation spectrum in the 112-type iron-based superconductor Ca0.82La0.18Fe0.96Ni0.04As2 (CaLa-112). The results showed that in-plane dispersions and the bandwidth of spin excitations in CaLa-112 closely resemble those in 122 systems. While the total fluctuating moments were larger in CaLa-112, the dynamic correlation lengths were similar, suggesting a common magnetic origin for superconductivity in iron arsenides.

Summary: We compared the performance of different atom spin gyroscopes in terms of Allan deviation, finding that the Rb-87-Xe-129-Xe-131-N-2 atom spin gyroscope with higher SNR exhibited better performance. By applying magnetic field feedback, the magnetic-field-induced noise was eliminated, improving the system's performance.

Summary: Using x-ray photon correlation spectroscopy, fluctuations in stripe-type spin order of a layered nickelate were observed on timescales of tens of minutes across a wide temperature range. These fluctuations exhibit anomalous temperature dependence, slowing down at intermediate temperatures and speeding up during heating and cooling, reflecting a direct connection with spatial correlations. The decay of nickelate stripe correlations at low temperatures, similar to the competition between stripes and superconductivity in cuprates, occurs through loss of both spatial and temporal correlations.

Summary: Iron-based pnictides exhibit a variety of ordered states and transport properties, without evidence of a pseudo-gap opening in the normal state. The Hall coefficient changes sign at low temperatures, and the resistivity shows a broad hump in the same temperature range. These unusual transport properties are inherently associated with high temperature superconductivity in iron-based superconductors.

Summary: The study identifies a hybrid Higgs mode in iron-based high-temperature superconductors and demonstrates its quantum control by light. The tunable coherent oscillation of the complex order parameter in these superconductors suggests the appearance and control of the Higgs mode through light tuning of interband interaction.

Summary: The quasi-two-dimensional thin films of iron-based superconductors have been established as a new high-temperature platform for hosting intrinsic time-reversal-invariant helical topological superconductivity. Experimental results have shown that an applied electric field can serve as a topological switch for helical Majorana edge modes in FeSC thin films.

Summary: We demonstrate the formation of robust zero-energy modes near magnetic impurities in the iron-based superconductor FeSe1-xTex. The Zeeman field generated by the impurity favors spin-triplet interorbital pairing over the spin-singlet intraorbital pairing found in the bulk. The preferred spin-triplet pairing preserves time-reversal symmetry and exhibits topological properties, with robust, topologically protected zero modes emerging at the boundaries between different pairing states.

Summary: The study presents V-51 NMR and inelastic neutron scattering (INS) measurements on the quasi-1D antiferromagnet BaCo2V2O8 under transverse field. It reveals a 1D quantum critical point (QCP) at H-c(1D) approximately 4.7 T and provides an unambiguous experimental realization of the massive E-8 phase in the compound. The results offer a new experimental route for exploring the dynamics of quantum integrable systems and physics beyond integrability.

Summary: In this paper, we reformulate the CTMRG method into a variational bilevel optimization algorithm in the context of tensor network states. The method is successfully applied to efficiently evaluate the partition function of classical statistical models represented by infinite tensor networks. The results obtained from applications in the dimer model and classical spin models demonstrate the effectiveness of this method.

Summary: By using high-pressure 11B nuclear magnetic resonance measurements, we have observed a magnetic field-induced plaquette singlet to antiferromagnetic transition in the quantum magnet SrCu2(BO3)2. The first-order signatures of the transition weaken with increasing pressure, and quantum critical scaling is observed at the highest pressure. These findings provide an experimental platform for investigating the deconfined quantum critical point.

Summary: The single crystals of Na2Co2TeO6 exhibit complex low-temperature phase behaviors, including a new thermal phase transition with 2D and 3D long-range magnetic orders. Excitations from the 3D order support a triple-q description, contrary to the commonly accepted zigzag nature, indicating a fundamental feedback on high-energy excitations. These findings suggest Na2Co2TeO6 as a spin-orbit entangled frustrated magnet with rich physics.
