Dynamic competition between Cooper pair and spin density wave condensation

Quantum matter phases may coexist microscopically even when they display competing tendencies. A fundamental question is whether such a competition can be avoided through the elimination of one phase while the other one condenses into the ground state. Her ...

Potential energy surfaces from many-body functionals: Analytical benchmarks and conserving many-body approximations

Giovanna Lani, Nicola Marzari

We investigate analytically the performance of many-body energy functionals, derived by Klein, Luttinger, and Ward, at different levels of diagrammatic approximations, ranging from second Born, to GW, to the so-called T matrix, for the calculation of total ...

Efficient and Stable Perovskite Solar Cells with a Multifunctional Spiro-Based Hole Transport Material

Mohammad Khaja Nazeeruddin

The widely used spiro-OMeTAD exhibits moderate interaction with the perovskite layer, which does not decrease the defect on the perovskite surface, thus limiting the photoelectric performance of perovskite solar cells. In this work, the spiro-OMeTAD struct ...
