Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in ...

Mathematical classical mechanics is underpinned by Hamiltonian flows on symplectic and more general Poisson manifolds, with conserved energy functions defining vector fields whose integrability is ...

(University of Birmingham) The quantum world is mind-bogglingly counterintuitive: at the smallest scales, basic physical qualities like position and speed are murky, and time as we know it doesn't ...

Physicists have built a real-number version of quantum mechanics that makes all the same predictions as the standard theory, ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

Input/output is the term for time before and after a particular physical moment or scenario, and in certain quantum scenarios, those ‘befores’ and ‘afters’ can be interchangeable. Researchers have ...

In a new study published in Physical Review D, Professor Ginestra Bianconi, Professor of Applied Mathematics at Queen Mary University of London, proposes a new framework that could revolutionize our ...

Add Yahoo as a preferred source to see more of our stories on Google. Theoretical physicists have figured out how to reverse the arrow of time in a quantum system. The arrow of time marches forward.

Quantum mechanics has long relied on complex numbers to describe the strange behavior of particles, from tunneling to ...
