Optimal control theory provides a mathematical framework for devising strategies that steer dynamical systems towards a desired performance while minimising a prescribed cost function. In recent ...

Recent advancements in thermodynamics have increasingly drawn on the language of differential geometry and systems control to reformulate classical principles. Geometric structures offer a rigorous ...

Controlling magnetic states in materials typically requires continuous power or only works in rare, specialized systems. Researchers developed a general theory showing how electric fields can ...

During the latter part of the 20th century, string theory was put forward as a unifying theory of physics foundations. String theory has not, however, fulfilled expectations. That is why we are of the ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...
