  abstract     = {{Laser Powder Bed Fusion (PBF-LB/M) enables significant performance enhancements in tool and mold making via the integration of complex, conformal cooling channels. However, high manufacturing costs of monolithic components and material-specific defect susceptibility still hinder widespread industrial adoption. Within the collaborative project WerKo3D, the scaling, process qualification, and structural design of the novel tool steel Printium 13 were successfully investigated to lower market entry barriers for additive tooling applications. An industrial batch of 50 kg of Printium 13 powder was produced via vacuum inert gas atomization and thoroughly characterized. Utilizing a Design of Experiments (DoE) approach on an SLM 280 system, an optimized process window was established, yielding a relative density of about 99.99%. Subsequent heat treatment parameterizations revealed a superior mechanical property profile combining high hardness with enhanced impact toughness compared to conventional AISI H13 tool steel, alongside ultimate tensile strengths up to 1,600 MPa. To reduce build times and material consumption, a segmented shell-core tool design was conceptualized and numerically optimized via coupled CFD and FEM simulations. The functional demonstrator - a sprue insert for aluminum die casting - was additively manufactured without cracking, heat-treated, and finish-machined to final dimensions. Furthermore, a two-day training and knowledge-transfer program was realized to disseminate design guidelines to industry stakeholders. The findings validate the complete process chain from powder atomization to crack-free hybrid tool manufacturing.}},

                    High-harmonic generation in solids enables probing of strong-field electron dynamics in condensed matter and the development of compact ultrafast light sources. Whereas most studies have focused on above-bandgap high-order harmonics, which are usually interpreted through short electron-hole trajectories that recombine within one optical cycle, the microscopic origin of low-order emission near the bandgap remains poorly understood. Here, we investigate near-bandgap harmonic generation in ZnO by combining semiconductor Bloch equations with a complex-time quantum-trajectory analysis. Our results indicate that these harmonics are not a continuation of the short trajectory. Rather, they originate from multiple-scattering trajectories, in which the electron-hole pair undergoes repeated Bragg scattering at the Brillouin-zone boundary and electron-hole reencounter near the

We identify that the imaginary part of the electron-hole displacement provides a practical diagnostic of the residual tunneling memory. Real-space electron-hole overlap alone does not imply coherent recombination unless the full complex displacement vanishes. These results clarify the microscopic picture of near-bandgap harmonic emission in ZnO and offer a framework for interpreting phase-resolved strong-field dynamics in solids.

  abstract     = {{Approval of products in safety-sensitive areas, such as medical technology, requires considerable effort. Companies must comply with numerous regulations for such product approvals. This results in requirements for processes, methods, tools and organizations throughout the product life cycle. A proven approach to handling regulatory requirements is the application of product lifecycle management (PLM) platforms. Applying PLM platforms (e.g. Teamcenter, 3DExperience) poses challenges in designing compliant processes as well as adapting methods and tools. For example, in medical technology, ISO 13485 specifies an industry-specific product engineering process. The exemplary adaptations of requirements engineering methods and related support – e.g. MBSE including Requirements Diagrams – are not intuitively apparent. Existing literature primarily regards these regulation-related challenges as boundary conditions, offering only vague operational solutions. Companies struggle to align PLM processes with regulatory requirements, yet few methods exist to support this integration. In this paper, a method is proposed that supports the application of regulation-centered PLM platforms and reduces effort in product approvals. The method is developed by applying a five-step approach. Existing literature on process models for applying PLM platforms is identified (1). The identified approaches are then analyzed to determine whether and to what extent they consider regulations in applying PLM platforms (2). Based on identified partial solutions from literature and findings from industry workshops, a new method is developed (3). The method comprises strategic level, process level, data level, pilot level, and operation level. Validation is conducted within a German medical technology company, containing proof of applicability determined through a pilot project (4) and proof of concept achieved through interviews (5). The method is applied to regulation-centered PLM for the use case ‘requirements engineering’. The concept is confirmed by experts in terms of applicability and transferability. The method supports engineers in applying regulation-centered PLM platforms, leading to reduced effort.}},

                    We develop a framework for identifying nonclassical speedups in systems with polarization, likewise spin degrees of freedom. By confining the dynamics to the manifold of angular momentum coherent states, which act as the classical reference in this case, we compute the speed limit that bounds the rate of change of the state achievable without generating quantum coherence. A comparison with the unrestricted quantum speed limit enables the quantitative identification of speedups arising from polarization nonclassicality. We apply this framework to the cross-Kerr interaction, demonstrating a persistent speedup scaling as

  abstract     = {{Friction spinning is a metal forming process that can be used to manufacture various shapes by rotating a metallic workpiece relative to a blunt tool. When used as a hot metal forming process, the relative velocity between workpiece and tool is increased until substantial heat is generated due to friction. This frictional heat softens the workpiece and allows it to be more readily shaped. However, the process's complex interactions between mechanical, frictional and thermal effects pose significant challenges for numerical modelling. The present study outlines a numerical model that uses the arbitrary Lagrangian–Eulerian (ALE) formulation in a rotating frame to simulate the friction spinning process. The key enabler is an incremental ALE formulation with reference‐velocity‐based remapping that allows for severe deformation and large rotational motion while preserving path‐dependent constitutive history variables. Proof‐of‐concept examples demonstrate its ability to simulate the upsetting of rods and rivets by friction spinning. The potential of the ALE formulation for modelling friction spinning is thereby confirmed, which paves the way for further research, model enhancements, parameter identifications and applications.}},
