Heriot-Watt Team Simulates Path to Higher Temperature Superconductivity

Two-dimensional mixed dimensional models support high-Tc superconductivity, overcoming previous simulation limitations imposed by classical computational methods. Thomas Köhler and Adrian Kantian at Heriot-Watt University used matrix product state plus mean field theory, a technique combining established modelling approaches, to identify conditions under which these systems exhibit superconducting behaviour. This provides practical guidelines determining when size limitations affect constructing larger systems from smaller units. Combining one-dimensional systems creates two-dimensional models potentially exhibiting high-Tc superconductivity; this approach bypasses…
