Quantum mechanical theory of optomechanical
... A major advantage of triply resonant optomechanical systems is the ability to provide resonant enhancement for both optical-pump and anti-Stokes light in addition to the mechanical mode [1] (Figure 1a). Such systems have been predicted to cool acoustical modes [2]. Of particular interest is a recent ...

... True: A photon is a unit of light energy. Can have one photon, two photons, etc. Cannot have 1.5 photons of red light. 2. Every blue photon has the same amount of energy as every other blue photon. True: A photon of a specific color of light has a specific energy. All photons of that exact color of ...

... found, we can’t define the magnetic field B in terms of the magnetic force per unit north pole. We will see instead that magnetic fields result from charges in motion—not from stationary charge or poles. This fact will be covered later. ...

... Regarding academic integrity, I will enforce policies as laid down in Section IV:D of the Student Responsibilities outlined in the Student Code. Specifically, no cheating or other forms of academic dishonesty will be tolerated. The first instance of cheating will result in a zero on that assignment. ...

Time in physics
Time in physics is defined by its measurement: time is what a clock reads. In classical, non-relativistic physics it is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.
