Where are you right now? Until you interact with another particle you could be any number of places within a wave of probabilities. This is only one way that quantum mechanics challenges our perception of reality. Matt dives into these...

Paradoxically, the most promising prospects for moving matter around faster than light may be to put a metaphorical brick wall in its way. New efforts in quantum tunneling - both theory and experiment - show that superluminal motion may...

How does a robin know to fly south? The answer might be weirder than you think: Quantum physics may be involved. Jim Al-Khalili rounds up the extremely new, extremely strange world of quantum biology, where something Einstein once called...

In the late 1970s, two physicists in Switzerland set out to invent a new type of microscope using quantum physics that would allow them to do something no one had ever done before: see the individual atoms in a sheet of metal.

While you might not think about quantum mechanics being part of your everyday life, it turns out that it might play a role in some of the most familiar things, from the sunlight in the trees to the nose on your face! Chapters View all...

The biggest surprise of discovering the Higgs boson? That there were no surprises. Gian Giudice talks us through a problem in theoretical physics: what if the Higgs field exists in an ultra-dense state that could mean the collapse of all...

Quantum tunneling happens when a particle seemingly teleports across a barrier. But despite how instantaneous this event sounds, recent research suggests that it doesn’t happen nearly as fast as you might think.

Could the universe be in a metastable, or false vacuum state? Could there be a looming vacuum catastrophe waiting to happen? Is the universe doomed?



This is related to the Higgs boson and the heaviest...

What is this mysterious quantum tunneling effect, where does it come from? And why is it one of the most important phenomena in physics?

Quantum mechanics shows that quantum objects have a wave-particle...

In this video, I summarize All Nuclear Physics in about 10 minutes. Atoms are made of a positively charged nucleus surrounded by negatively charged electrons. The nuclei of atoms are made up of protons and neutrons. These are called...

Now that we've covered the particle in a box, we are familiar with the concept of a quantum problem. Let's move on to our second quantum problem, that of the quantum barrier potential. With this one, we don't have an infinite square well...

In the previous tutorial we introduced our second quantum problem, that of the quantum barrier potential. Again, this involves a free particle that encounters a barrier of finite potential. We've already solved the Schrödinger equation...

Particle in a Finite Potential Well: Quantum Tunneling

With the Schrödinger equation for the quantum harmonic oscillator solved, we are ready to analyze and interpret our results. What can we learn from the probability density function? How does the probability of finding a quantum particle...
