Evidence Mounting That Dark Energy Evolves Over Time

New results from the Dark Energy Spectroscopic Instrument show dark energy may currently be weakening

According to the Standard Model of Cosmology, the expansion of our universe is driven by the simplest possible version of dark energy: an unchanging 鈥榗osmological constant鈥� called lambda. That longstanding model may be about to change.

Quantum computing one ion at a time

A quantum computer uses the properties of superposition and interference to solve problems that are impossible with the computers and smartphones of today. However, building a quantum computer is an enormous physical and engineering challenge. In building a quantum computer, the first thing one needs to decide on is which quantum system, or 鈥渜ubit鈥�, is it going to use?

New quantum tool developed in groundbreaking experimental achievement

For the first time in history, scientists have created a device that recreates the properties of light using neutrons: the neutral subatomic particles found in the nucleus of an atom.

Dr. Michel Gingras: What We Can Learn from Frustrated Magnets

In the field聽of frustrated quantum magnetism, there are no textbooks. At least not yet. Dr. Michel Gingras, a leading physicist in the field of theoretical condensed matter, is engaged in a search for quantum magnets. That search has led him to study "spin ice", a magnetic material that has atomic magnetic moments as elementary degrees of freedom that are subject to "frustrated" interactions. Learn more about Dr. Gingras, spin ice, and what the future of theoretical聽condensed matter physics might hold.
