How quantum weirdness is improving electronmicroscopes physrevlett
Two new advances from the lab of UO physicist Ben McMorran are refining the microscopes. Both come from taking advantage of a fundamental principle of quantum mechanics: that an electron can behave simultaneously like a wave and a particle. It's one of many examples of weird, quantum-level quirks in whichOne of the studies finds a way to study an object under the microscope without making contact with it, preventing the scope from damaging fragile samples.
With the right alignment of these beam-splitting diffraction gratings,"the electron comes in and gets split into two paths, but then recombines such that it only goes to one of the two possible outputs," said Amy Turner, a graduate student in McMorran's lab who led the first study."The idea is that when you put in a sample, the electron's interaction with itself is interrupted.
That approach could reveal sensitive atomic-level nuances about a sample, understanding the way that particles are interacting in a sample.

Physicists embark on a hunt for a long-sought quantum glowFor 'Star Wars' fans, the streaking stars seen from the cockpit of the Millennium Falcon as it jumps to hyperspace is a canonical image. But what would a pilot actually see if she could accelerate in an instant through the vacuum of space? According to a prediction known as the Unruh effect, she would more likely see a warm glow.

Study points to physical principles that underlie quantum DarwinismAt the atomic and subatomic scales, objects behave in ways that challenge the classical worldview based on day-to-day interactions with macroscopic reality. A familiar example is the discovery that electrons can behave as both particles and waves, depending on the experimental context in which they are observed. To explain this and other phenomena, which appear contrary to the laws of physics inherited from previous centuries, models that are self-consistent but have contradictory interpretations have been proposed by scientists such as Louis de Broglie (1892-1987), Niels Bohr (1885-1962), Erwin Schrödinger (1887-1961) and David Bohm (1917-1992), among others.
