About
Much of modern technology owes to our deep understanding of electronic properties of materials. That understanding is rooted in intertwined empirical, experimental and theoretical knowledge. I work on the theoretical aspects of materials, in other words, I solve mathematical models and perform large scale computer simulations to understand electronic properties of materials that escape conventional tools of theoretical physics. The challenge of these “quantum materials” is rooted in the difficulties of handling problems where wave-particle duality is prevalent. Some of the algorithms that we have developed are used today in powerful software that allows to predict on a computer the properties of classes of materials that were impossible to simulate before. Some of these materials have exceptional properties, such as transporting electricity without resistance (superconductors), or the conversion of heat in electrical current in a very efficient way (large thermopower) or exceptional cooling properties without greenhouse gases (large magnetocaloric effect).
