Harvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control ...

Dr. Myerburg answers the question: 'What Is Pre-Excitation, Is It Dangerous?' — -- Question: On a routine EKG I was diagnosed to have pre-excitation. What is that and is it dangerous?

Quantum materials exhibit remarkable emergent properties when they are excited by external sources. However, these excited ...

A new molecule that lets energy hop around quickly within its structure makes the upcycling of light more efficient and ...

To make a working nervous system, only two forces are necessary: excitation and inhibition. Excitatory signaling from one cell to the next makes the latter cell more likely to fire. Inhibitory ...

The exceptionally low 8 eV excitation energy corresponds to light in the vacuum ultraviolet, which can be generated by a laser. As a result, the transition could be used to create an accurate clock.

The Excitation Emission Matrix (EEM) is a specific measurement that is becoming more and more respected and widely used within the field of fluorescence spectroscopy. An EEM is essentially a three ...

From this procedure we are able to see that the response of the building is dominated by the jth mode when the frequency of excitation is tuned to near the jth natural frequency. Shown below are ...
