${\displaystyle {i\hbar {\frac {\partial }{\partial t}}\Psi (\mathbf {r} ,\,t)={\hat {H}}\Psi (\mathbf {r} ,\,t)}}$ The Schrödinger equation, use to describe how the quantum state of a physical system changes with time

Between 1966 and 1968, Abdus Salam's doctoral students had returned to Pakistan after earning their doctorates and experience.[3] These physicists had been under Abdus Salam's influence and were eager to establish an institute of physics.[3] Abdus Salam enabled them to engage their research in theoretical physics and to establish the country's first school of theoretical physics.[3] Abdus Salam provided his support to establish the institute and gave the founding directorship of the institute to his pupil student, Riazuddin.[3]

Abdus Salam and Riazuddin founded the first "Theoretical Physics Group (TPG)" in 1968 that gave birth to Pakistan's school of theoretical physics.[3] The infrastructure was built by the Pakistan Atomic Energy Commission (PAEC) after Raziuddin Siddiqui also persuaded the PAEC to provide its full support to establish this institute as a birthplace of theoretical physics.[3] The new institute was re-established at the University of Islamabad and, Salam, Siddiqui and Bhutto convinced the authorities in Pakistan, specifically President Ayub Khan, to make the proposed university a research institution.[3] Siddiqui convinced the chairman of PAEC, dr IH Usmani, to send all the theoreticians in PAEC to the Institute of Physics at the University of Islamabad to form a theoretical physics group.[3]
