One of the most mind-blowing areas of quantum mechanics is
entanglement: two or more particles separated in space can
have physical properties that are correlated. A measurement performed
on one particle will tell us the result of the same measurement taken on
an entangled particle. Entanglement is important but difficult to study,
both in terms of a theoretical understanding and doing experiments. While...
The last word a physicist wants to hear at a cocktail party is “quantum.” The science of quantum mechanics has been so badly butchered and misrepresented by well-meaning writers, that others have taken the oversimplifications and run with them.
In 1927, Werner von Heisenberg documented what he referred to as an “Uncertainty Principle” governing quantum mechanics. The Uncertainty Principle holds that an observation cannot precisely reveal both the position of a particle at a point in time and its momentum. The more the...

The field of particle physics spent much of the last century converging on the "standard model" that describes subatomic particles and the forces by which they interact. Ambitious research that began in the early 1900s with hot-air balloon experiments aimed at catching cosmic rays, and followed later in the century with accelerator-based experiments, led to the extraordinary success of the standard model. Nonetheless, the excitement in particle physics often lies not with the vast body of...Read Full Story
Researchers at the Ecole Polytechnique Fédérale de Lausanne (EPFL, Switzerland) and the Max Planck Institute of Quantum Optics (MPQ, Garching near Munich) have demonstrated a microscopic system in which light can be converted into a mechanical oscillation and back. This interaction is so strong that it becomes possible to control the motion of the oscillator at the level where quantum mechanics governs its behaviour (Nature, 2 February 2012). Since the early 20th century, it is known that the...Read Full Story

Understanding Quantum Physics: An Advanced Guide for the Perplexed
Quantum physics is admittedly the most difficult subject to understand. Physicists, let alone students and laymen, are still puzzled by it today. As Richard Feynman once famously claimed, nobody understood quantum mechanics. The crux of the matter lies in the meaning of the mysterious wave function in the theory. An electron is represented by a wave...Read Full Story
Researchers shed light on the mystery surrounding energy-rich molecules in interstellar clouds Surprisingly, hydrogen cyanide and its far more energetic isomer, hydrogen isocyanide, are present in almost equal amounts in cold interstellar gas clouds. Scientists from the Max Planck Institute for Nuclear Physics have succeeded in explaining how this happens through experiments carried out in the Heidelberg ion storage ring. During interstellar synthesis hydrogen cyanide forms as a hot hybrid...Read Full Story
A research team led by physicists at the University of California, Riverside has identified a property of "bilayer graphene" (BLG) that the researchers say is analogous to finding the Higgs boson in particle physics. Graphene, nature's thinnest elastic material, is a one-atom thick sheet of carbon atoms arranged in a hexagonal lattice. Because of graphene's planar and chicken wire-like structure, sheets of it lend themselves well to stacking.
The image shows a bilayer graphene schematic...Read Full Story

Quantum mechanics news, blogs, and links. According to Wikipedia: Quantum mechanics is a fundamental branch of theoretical physics that replaces classical mechanics and classical electromagnetism at the atomic and subatomic levels. It is the underlying mathematical framework of many fields of physics and chemistry, including condensed matter physics, atomic physics, molecular physics, computational chemistry, quantum chemistry, particle physics, and nuclear physics. Along with general relativity, quantum mechanics is one of the pillars of modern physics.
