Low Temperature Physics

The science which deals with the production and maintenance of below normal temperature or at absolute zero and the processes and phenomena that takes place only at those temperatures is referred to as Low Temperature Physics. It is also known as “Cryogenics” which means producing cold in Greek language. Kelvin temperature scale which is based on the behavior of an idealized gas  is used as scale or measure the temperatures in low-temperature physics. The simplest way by which we can achieve low temperature is or to cool a substance is to bring it into contact with another substance that is already at a low temperature.
