| | | | | | Excitons, Superconductivity and Charge Order
Going against the popular belief in condensed matter theory that excitons and charge order are always bad for superconductivity, we show that in some cases the presence of excitons can actually enhance the superconducting transition temperature. | |  |

|  | | Broken Unitarity and Quantum Measurement
Unitarity, the guiding principle of quantum physics, can spontaneously break down in macroscopic objects. In addition to explaining their classical dynamics, this loss of unitarity may also help to better understand the ability of large objects to function as quantum measurement machines. |

| Thin Spectrum in Superconductors
We have shown that finite-size superconductors have low-energy, in-gap states associated with their spontaneous breaking of a global phase symmetry. Because of this so-called thin spectrum of states, superconducting qubits can stay quantum coherent only for a limited time. | |  |
