Measuring Zak phase in room-temperature atoms

In topological insulators, global geometric phases of energy bands determine the existence of unidirectionally propagating edge states, which are immune to local defects, bringing a new stage for designing noise-resilient ...

How quantum physicists are looking for life on exoplanets

The world that quantum physicists study with a trained eye is the very same world that we non-scientists navigate every day. The only difference is that it's been magnified to scales incomprehensibly small and large.

Research improves upon conventional LED displays

LED lights have become ubiquitous lighting solutions for homes and businesses, but when it comes to large, high-resolution displays, traditional LEDs have documented disadvantages. LED displays use a high voltage and a factor ...

Developing the building blocks of the future for photovoltaics

An international research team led by the University of Göttingen has, for the first time, observed the build-up of a physical phenomenon that plays a role in the conversion of sunlight into electrical energy in 2D materials. ...

New quantum technology combines free electrons and photons

Faster computers, tap-proof communication, better car sensors—quantum technologies have the potential to revolutionize our lives just as the invention of computers or the internet once did. Experts worldwide are trying ...

Ultracold atoms dressed by light simulate gauge theories

Our modern understanding of the physical world is based on gauge theories: mathematical models from theoretical physics that describe the interactions between elementary particles (such as electrons or quarks) and explain ...
