Spin-based phenomena are the central concept in the field of spintronics, where efficient spin current generation, spin-to-charge conversion, and spin transport are the key concepts for the development of next-generation electronic devices. With the extensive availability of femtosecond lasers a new research field of ultrafast spintronics has opened up, aiming to understand spin-transport on the ultrafast time scales. [...]

Energy efficiency is becoming increasingly critical in the exascale era, where even small improvements at the GPU or node level can translate into significant energy savings and cost reductions. JUPITER, the first exascale supercomputer powered by NVIDIA GPUs, underscores the importance of understanding energy behavior across diverse applications. [...]

Nuclear magnetic resonance (NMR) is a powerful tool for probing molecular structure and dynamics, but conventional high-field systems are bulky and suffer from field inhomogeneities. Zero- to ultralow-field (ZULF) NMR overcomes these limits by exploiting internal spin interactions in a magnet-free, shielded environment. [...]

We analyze the domain of validity of a quantum optical model that describes the effects of gravitational redshift on the quantum state of photons that propagate in curved spacetime. This model assumes that the modes defining the initial state of the photon are mixed with an auxiliary environment mode via an effective multimode mixer. [...]

As conventional CMOS technology approaches its scaling limits, alternative memory and logic device concepts are being actively pursued. Among these, resistive and ferroelectric switching mechanisms have emerged as promising candidates for non-volatile memory technologies due to their potential for high density, low power consumption, and compatibility with existing semiconductor processes.
