Observations on A as a function of excitation frequency (for undamped response) For low frequencies of excitation (omega < omega n ), the response amplitude A is approximately F 0 /K, or the static ...

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.

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

The balance between neural excitation and neural inhibition is crucial to healthy cognition and behavior. A brain dominated by glutamate would only be capable of exciting itself in repeated bursts ...

Cassidy notes that the investigating engineers identified a process called “synchronous lateral excitation” that was at the root of the problems, ... he or she produces a slight sideways force.
