Quantum effects in condensed matter at high pressure
Institute for High Pressure Physics, Russian Academy of Sciences, Troitsk, Moscow, Russian Federation
Experimental data characterizing influence of quantum effects on the equation of state and melting of substances at high pressure are reviewed. It is shown that quantum isotope effects tend to increase upon compression of substances with a predominately Coulomb interaction, whereas compression of
the ’van der Waals substances’ reveals the opposite trend. The ’cold’ melting of ’Coulomb substances’ at high pressure is discussed.
