Many natural processes, ranging from magnetism to chemical reactions, entail the movement and rotation of particles at very small scales. In quantum mechanics, particles exhibit both particle-like and ...

Physicists have proposed a way to extract the internal quantum states of electron wave packets by analyzing how those packets scatter off atoms. The approach, grounded in theoretical derivations ...

PROVIDENCE, R.I. [Brown University] — New research by physicists from Brown University puts the profound strangeness of quantum mechanics in a nutshell — or, more accurately, in a helium bubble.

Electrons detached from atoms by photoionization carry valuable information about light-atom interactions. Characterizing and shaping the electron wave function on its natural timescale is of ...
