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.

Quantum nano-mechanics. Quantum jumps in atomic physics. Continuous transitions between quantum states in quantum‒classical mechanics for molecular and chemical physics involve both chaotic (dozy ...

Physicists have now demonstrated experimentally the ability to coherently manipulate the wave function of a free electron down to the attosecond timescale (10-18 of a second). The team also developed ...

Solving the Schrödinger equation for the many-electron wave function has been a key challenge in quantum chemistry for decades. Anything other than a one-electron problem, such as a hydrogen atom, ...

For the first time, researchers have successfully measured the shape of an electron as it moves through a solid, opening a new window into understanding how electrons behave in different materials.

How it works: illustration of the quantum twisting microscope in action. Electrons tunnel from the probe (inverted pyramid at the top) to the sample (bottom) in several places at once (green vertical ...

Philosophical Transactions: Mathematical, Physical and Engineering Sciences, Vol. 376, No. 2115, Theme issue: Modern theoretical chemistry (13 March 2018), pp. 1-16 (16 pages) An implementation of the ...

INTRODUCTION: Density functional theory (DFT) is a widely used method for calculating the electronic properties of materials. The method is based on the idea of approximating the many-electron wave ...

Australian researchers made a quantum leap in leading the push towards creating a fully functional quantum computer. Michelle Simmons and her team at the University of New South Wales were able to ...

Fractals are a source of endless fascination to me. Life itself relies on many of the concepts of fractals: trees are fractal, as are feathers, coast lines, and many other things in nature. Indeed, it ...
