Abstract: We study the effects of pressure on the electron-phonon interaction in MgB2 using density-functional-based methods. Our results show that the superconductivity in MgB2 vanishes by 100 GPa, and then reappears at higher pressures. In particular, we find a superconducting transition temperature T-c approximate to 2 K for mu(*)=0.1 at a pressure of 137 GPa.
