They can help interpret experiments, thus providing virtual laboratories that complement real laboratories and mathematical theories. Examples will illustrate quantum simulations, that is, simulations at the microscopic level , driven by the laws of quantum mechanics. After Scientific computing is now on a par with laboratory experiment and mathematical theory as a tool for research in science and engineering.
Simulations can substitute for experiments that are impossible or impracticable.
They can help interpret experiments, thus providing virtual laboratories that complement real laboratories and mathematical theories. Examples will illustrate quantum simulations, that is, simulations at the microscopic level , driven by the laws of quantum mechanics. These simulations, together with those in the last two decades, highlight the important role of computational quantum mechanics in addressing problems in condensed matter physics, materials science and chemical physics. With applied pressure, the electrical resistivity develops a peak near 30 K that initially moves to lower temperature with increasing pressure, unlike other Ce-based materials. The superconducting transition sharpens and moves to higher temperature with applied pressure.
