Scientists observe how superconducting nanowires lose resistance-free state
Even with today's invisibility cloaks, people can't walk through walls. But, when paired together, millions of electrons can.

Evidence of macroscopic quantum tunneling detected in nanowires
A team of researchers at the University of Illinois has demonstrated that, counter to classical Newtonian mechanics, an entire collection of superconducting electrons in an ultrathin superconducting wire is ...

Physicists show that superfluid light is possible
(PhysOrg.com) -- Superfluidity – the phase of matter that enables a fluid to move up the sides of its container – has been known about since the 1930s. Since then, superfluidity has become a prime ...

Can fluid dynamics offer insights into quantum mechanics?
In the first decades of the 20th century, physicists hotly debated how to make sense of the strange phenomena of quantum mechanics, such as the tendency of subatomic particles to behave like both particles ...

Would a molecular horse trot, pace, or glide across a surface?
(PhysOrg.com) -- Ludwig Bartels's lab has studied a class of molecular machines that 'walk' across a flat metal surface in order to determine how a quadrupedal molecular machine would move.

Search for the bridge to the quantum world
Science fiction has nothing over quantum physics when it comes to presenting us with a labyrinthine world that can twist your mind into knots when you try to make sense of it.

Understanding light at the nanoscale: a nano-sized double-slit experiment
Before nanotechnology can reach its full potential, researchers must understand the way things work on the nanoscale—which is often very different from the macroscopic world. One of these areas is light, and ...

Electrons caught in the act of tunnelling
We have to climb a mountain in order to conquer it. In quantum physics there is a different way: objects can reach the opposite side of a hill simply by tunnelling through it, instead of laboriously climbing ...
