Summary: In this study, the transient evolution of charge density wave (CDW) correlations in cuprate superconductors after the quench of superconductivity was tracked using ultrafast resonant soft x-ray scattering. The results showed a nonthermal response of CDW order characterized by a doubling of the correlation length within approximately 1 picosecond of the superconducting quench. These findings suggest that the interaction between superconductivity and CDWs manifests inhomogeneously through disruption of spatial coherence.

Summary: Combining magnetism and nontrivial band topology can achieve the quantum anomalous Hall (QAH) effect at high temperatures for lossless transport applications. In this study, a heterostructure consisting of two single-septuple layers (1SL) of MnBi2Te4, an ultrathin few quintuple layer (QL) Bi2Te3, and another 1SL MnBi2Te4 was grown via molecular beam epitaxy. The electronic structure was probed using angle-resolved photoelectron spectroscopy, and strong hexagonally warped massive Dirac fermions and a bandgap of 75 +/- 15 meV were observed. The magnetic origin of the gap was confirmed, and these findings provide insights into magnetic proximity effects in topological insulators and a promising platform for realizing the QAH effect at elevated temperatures.

Summary: We have investigated the electric and thermal transport properties of two-dimensional van der Waals ferromagnetic Fe3GeTe2. The low-temperature longitudinal resistivity in the ab plane is influenced by impurity scattering, quantum correction, and electron-electron interaction. The low-temperature specific heat consists of linear and cubic temperature terms, corresponding to contributions from electrons and phonons. The heavy-fermion state in Fe3GeTe2 can be described by Landau's Fermi liquid theory. The Kadowaki-Woods ratio in Fe3GeTe2 is five times larger and smaller than that of transition metals and heavy-fermion compounds, respectively. Moreover, the thermal conductivity along the c axis increases monotonically with temperature, exhibiting a phonon glass electron crystal behavior due to boundary scattering of phonons. The observed T1.35 dependence of the lattice thermal conductivity at low temperatures arises from the combined effect of highly anisotropic dispersion and strong impurity scattering of phonons.

Summary: Recent studies have shown that the ultimate load-bearing and deformation capacity of weldments from ultra-high-strength steel are affected by the heat-affected zone, necessitating analysis of its mechanical properties. A model for fracture assessment of friction-welded joints in direct-quenched armor steel was successfully developed, with the impact of subcritically heated zones on model accuracy examined. Different numerical models were tested, with neglecting the subcritical zone resulting in an overestimation of joint strength and alternative models failing to accurately assess fracture.

Summary: This study investigates the heat exchange phenomena during fast transient processes, especially in the context of Reactivity-Initiated Accidents (RIA) in nuclear reactors. The research focuses on quantifying the heat exchanges between a heating wall and a coolant, with a particular emphasis on the single phase convection mechanisms in the CABRI reactor. The study proposes a method to model the heat transfer coefficient during transient events in the CABRI-RIA system, demonstrating the analytical model's potential for implementation in computational tools.

Summary: The study investigates the effect of interlayer exchange coupling J on chiral domain wall dynamics in synthetic antiferromagnetic spintronics. Different behaviors of domain walls are observed in regions with antiferromagnetic and ferromagnetic exchange couplings. The strongest antiferromagnetic exchange coupling point is determined, and a simple phenomenological model is proposed to explain the experimental results.

Summary: Quench hardening aims to improve the hardness and mechanical strength of steels by transforming their microstructure, often using polymeric solutions for quenching. The concentration of these solutions affects the formation of martensite and the resulting hardness of the steel. Increasing concentration leads to reduced martensite formation and lower hardness.

Summary: Through magnetotransport experiments, researchers observed Rashba-driven unidirectional magnetoresistance in few-nanometer-thick films of PdCoO2, which competes with the anomalous Nernst effect below the Curie point. They estimated the Rashba coefficient and suggested that delafossites qualify as a new family of oxides for nanospintronics and spinorbitronics.

Summary: This study reports the magnetic susceptibility of LiHoF4 near a transverse-field quantum critical point and reveals a new type of phase transition called mesoscale quantum criticality. The results show that the observed mesoscale pattern formation in the surroundings of quantum phase transitions is in excellent agreement with the theoretical predictions. These findings provide valuable insights into the understanding of mesoscale patterns in the vicinity of quantum phase transitions.

Summary: In this study, an exchange bias of approximately 90 mT in a van der Waals ferromagnet encapsulated by two antiferromagnets at 5 K is reported. The value of this exchange bias can be highly tunable by field coolings, paving the way for designing and controlling 2D spintronic devices made of atomically thin van der Waals magnets.

Summary: This study investigates the saturation of defect density in an atomic Bose gas rapidly cooled into a superfluid phase. Results show that the number of quantum vortices exhibits a Poissonian distribution in both slow and fast quenches, with the mean vortex number saturating in the latter case. The saturation is attributed to early-time coarsening in an emerging condensate, indicating an effect beyond the Kibble-Zurek mechanism.

Summary: Through lattice Boltzmann simulations, the rheological properties of an active emulsion were numerically studied, revealing the sensitivity of polar droplets to active injection and external forcing. Depending on the conditions, the system may exhibit asymmetric or symmetric states, shear thickening, and even negative effective viscosity with large external forcing. Additionally, a region of multistability was observed at intermediate activity levels, where a maximum entropy production principle played a role in selecting the most favorable state.

Summary: This study further explores systems in contact with multiple baths of different temperatures, considering their thermalization behavior. By using thermodynamic integration, the stationary distribution can be recovered based on measurements from a 'multi-reversible' transformation. The research shows that the system at each step can be described by a generalization of the Boltzmann-Gibbs distribution.

Summary: After a zero temperature quench, the kinetics of a one-dimensional Ising model with long-range interactions were studied. The interaction between spins decays as r-a, where a ≤ 1. It was found that only a fraction of the non-equilibrium trajectories exhibit coarsening domains, while the remaining trajectories quickly reach a magnetized state. The probability distribution of the domain sizes was computed for the cases displaying coarsening, showing a scaling behavior with an unusual a-dependent power-law decay. The average domain size was found to grow asymptotically linearly in time, which differs from the exponential decay observed when a > 1.

Summary: This study investigates the effect of long-range interactions on the abundance of striped metastable states in two-dimensional Ising ferromagnets. Monte Carlo simulations reveal that long-range interactions suppress the occurrence of striped metastable states at zero temperature, while at non-zero temperature the final state is always ordered.

Summary: The study reveals that in the two-dimensional Ising model with long-range coupling, when the temperature is quenched to zero, interfaces experience drift due to long-range interactions, making the system dynamics peculiar. In this case, the growth exponent is found to be z = 4/3, independent of sigma, demonstrating its universality.
