Negative Temperatures

The thermodynamic concept of temperature is defined by the following equation: $$T = \frac{\partial E}{\partial S}$$ where $E$ is the energy of the system and $S$ is the entropy. Now usually when the energy of a system increases or decreases it’s disorder, and hence it’s entropy, also increases or… Continue reading Negative Temperatures

Theoretical Physicists in India

There are many research centers and researchers in India working in hep-th (High Energy Physics, Theory), gr-qc (General Relativity/Quantum Cosmology) and quant-ph (Quantum Physics). However they are scattered all over the place and I have not been able to find a place which lists the names of places and individuals working in these fields in… Continue reading Theoretical Physicists in India
