## Material physics

### iodine lasers

##### Materials science; Material physics

A chemical laser that users iodine as a gain medium, and pumping is achieved by chemical or photo-dissociation of the molecules. It operates at a wavelength of 1253.73 nm in the far infrared region. ...

### gauge pressure

##### Materials science; Material physics

Gauge pressure is a relative pressure measured with respect to the atmospheric pressure. P absolute = P gauge + P atmospheric .

### transmission matrix

##### Materials science; Material physics

A matrix relating the transmitted wave amplitudes, transmitting through a structure to the incident wave amplitudes. \begin{pmatrix} B_1 \\ B_2 \\ \cdots \\ B_n \end{pmatrix} = \begin{pma ...

### Rankine cycle

##### Materials science; Material physics

A realistic heat engine cycle that more accurately approximates the pressure-volume cycle of a real steam engine than the Carnot cycle. The Rankine cycle consists of four stages: First, heat is added ...

### Dirac matrix

##### Materials science; Material physics

A four-dimensional matrix which is a component of the Dirac equation and which describes the operations of parity and space-time rotations of the spin degrees of freedom. There are several ...

### Gerard t'Hooft

##### Materials science; Material physics

Physicist from the University of Utrecht who notably contributed to the theory of electroweak forces, QED, gauge theories, etc. and won the Nobel Prize in physics.

### grand unification

##### Materials science; Material physics

Physics attempts to explain natural phenomenon in terms of a set of fundamental axioms. It is the general goal of physics to reduce this set to its simplest, or most fundamental form. Thus there are ...
