Abstract

Massively Parallel Simulations of the Cuprate High Temperature Superconductors

 The cuprate high-temperature superconductors hold great technological promise.  Non-perturbative, massively parallel simulations have played an essential role in developing an understanding of these materials, from establishing the validity of the most basic cuprate models, to the  inclusion of realistic effects such as lattice vibrations, disorder, and  chemical detail.  A fuller understanding of these realistic effects may lead to the development of better superconducting materials.  However, in the years since the discovery of the cuprates, the focus has shifted towards materials with  more complex phase diagrams and competing ground states, and correlated multilayers which hold the promise of new functionality. Computational  issues, such as the infamous minus-sign problem, preclude the use of conventional methods to study these systems, and are leading to the development of multi-scale many-body formalisms, algorithms and codes,  which will be an essential part of the future of computational many-body  materials physics.
