After conducting the dynamics of the two-spin system as described in (7) under intrinsic decoherence, we will now investigate the Hilbert-Schmidt and Bures distances, as well as the corresponding speeds through the lens of the quantum…

Lithium-ion battery RUL prediction based on optimized VMD-SSA-PatchTST algorithm
Whale optimization algorithm
The Whale Optimization Algorithm (WOA) is a metaheuristic inspired by nature that mimics humpback whale foraging behavior, specifically their spiral bubble-net hunting technique20. This algorithm integrates three…

Non-volatile electric-field control of room-temperature ferromagnetism in Fe3GaTe2 heterostructures
Construction and characterizations
In this study, we investigated a vertically vdW stacked multiferroic heterostructure comprising a 2D itinerant ferromagnet Fe3GaTe2, and a ferroelectric polymer P(VDF-TrFE), sequentially layered from the bottom…

Pseudochaotic many-body dynamics as a pseudorandom state generator
Pseudochaotic dynamics
We define pseudochaotic dynamics as a non-chaotic unitary time evolution with i. computational indistinguishability from chaotic time evolution via OTOCs, and ii. capability to generate pseudorandom states. The latter…

Aluminium-20 shatters nuclear norms with explosive triple-proton breakup
Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic nuclei. In particular, exotic decay modes like…

Physics – Characterizing a Top Superconductor
• Physics 18, s90
The material with the highest-temperature superconductivity at ambient pressure has received less attention than its easier-to-prepare relatives—until now.
The highest-temperature superconductor at…
