Summary: This article examines the relaxation process of strongly disordered systems of interacting quantum dipoles when locally excited, analyzing the dependence on frequency, temperature, and polarization. Both energy relaxation rates (T-1 times) and dephasing rates (T-2 times) are considered, leading to the discovery of a rich set of scaling laws for different systems in various dimensions.

Summary: In this study, a newly introduced mean-field model for the density of vibrational states of a structurally disordered system is explored. The investigation focuses on the vibrational properties of the system's ground state at zero temperature. The results show that different types of pseudogaps, from quadratic and delocalized to quartic and localized, emerge based on the parameters set, providing insights into the behavior of disordered systems at glass transition.

Summary: We investigate the effect of introducing a weak nonlinear on-site potential on the average number of critical points N over bar in a many-body system with disordered two-body interactions. We find that this dramatically increases N over bar exponentially with system size and provides a comprehensive understanding of the organization of critical points. Our findings extend solvable spin-glass models to more realistic models and have implications for glassy systems, nonlinear oscillator networks, and many-body interacting systems.

Summary: This study demonstrates the broadband enhancement of transmission through an opaque barrier due to mirror symmetry in microwave measurements. The impact of mirror symmetry can be further increased by tuning the degree of disorder within the cavity. Symmetrically placing randomly located scatterers can lead to an additional enhancement of the conductance.

Summary: We present a solution for the nonequilibrium dynamics of an interacting disordered system by adapting the equilibrium dynamical mean-field theory and the equilibrium coherent potential approximation methods. Our approach uses the Kadanoff-Baym-Keldysh complex time contour to study the dynamics of interacting disordered systems away from equilibrium. We obtain the equilibrium density of states of the disordered interacting system and observe the effect of disorder on the relaxation of the system.

Summary: This work justifies the linear response formula for the Hall conductance of a two-dimensional disordered system by controlling the dynamics associated with a random time-dependent Hamiltonian. A local adiabatic theorem is proven to tackle the unstable nature of spectral and dynamical localization and establish the failure of global spectral flow in disordered systems.

Summary: By combining experiment and molecular dynamics simulation, the ultrafast nanoscale crystal nucleation process in shocked soda-lime silicate glass is investigated. The connectivity of the atomic network is found to govern the propensity of nucleation, as revealed by adopting topological constraints theory. The densification of local networks inhibits further crystallization by creating an underconstrained shell around the growing crystal. These findings provide insights into the nanoscale crystallization mechanism of shocked materials from the perspective of topological constraint theory.

Summary: The biological evolution of a population is controlled by the fitness landscape. Evolution in changing environments resembles the athermal dynamics of disordered physical systems. By studying a model of antibiotic resistance evolution in bacteria, it is found that adaptive evolution also exhibits hysteresis loops and memory formation. The research provides a general framework for studying the evolutionary dynamics of biological systems in a changing environment.

Summary: In this study, we focused on investigating the necessary conditions for the appearance of infinite avalanches in disordered systems below the critical point. By examining the impact of factors such as the interface of flipped spins and the number of independent islands of flipped spins, we aimed to distinguish the effects originating from finite system size from the real necessary conditions for the appearance of infinite avalanches. We conducted numerical simulations on lattices of different sizes and explored other key parameters related to avalanche propagation.

Summary: This work investigates the long-term behavior of occupation imbalance in diffusive or subdiffusive transport regimes of disordered one- and two-dimensional many-body systems. It shows that memory effects from coupling slow and fast modes lead to a power-law decay of the imbalance, with the exponent determined by the transport law and spatial dimensionality.

Summary: The study introduces a machine learning model for predicting local electronic properties of disordered correlated electron systems. It shows that local electronic properties mainly depend on the immediate environment, and demonstrates good agreement between machine learning predictions and experimental data.

Summary: The critical exponents of continuous phase transitions in a Hermitian system depend only on its dimensionality and symmetries, known as the universality of continuous phase transitions. This study numerically investigates Anderson localization transitions in non-Hermitian two-dimensional systems with exceptional points. The results show that non-Hermitian systems with different symmetries exhibit the same critical exponent at exceptional points, which differs from known 2D disordered Hermitian and non-Hermitian systems. This suggests a superuniversality notion of Anderson localization transitions.

Summary: Studies have shown that real-world networks follow preferential attachment and detachment principles, but the dynamics of node ranking do not adhere to these principles. The ranking dynamics exhibit a non-monotonic curve, suggesting the existence of qualitatively distinct stability categories for nodes. These findings provide explanations for observed phenomena.

Summary: In composite materials composed of a soft polymer matrix and rigid, high aspect-ratio particles, the mechanical strength of the composite undergoes a transition when the density of incorporated particles exceeds a critical value. This phenomenon, known as rheological percolation, has been extensively studied in polymer-rod and polymer-platelet composites. However, the complete theoretical explanation and predictive description of mechanical percolation have remained elusive. In this study, the authors develop an algorithm to detect the rigidity percolation threshold in rod-polymer composites and explore its dependence on rod aspect ratio.
