Examining multi-band effects on the electronic compressibility of a 2D electron gas: Insights into the negative compressibility of LAO/STO In this study, we investigate the consequences of two electronic bands […]
Beyond BCS: An Exact Model for Superconductivity and MottnessHigh-temperature superconductivity in the cuprates remains an unsolved problem because the cuprates start off their lives as Mott insulators in which no […]
Spectral bulk-boundary correspondence of odd-frequency Cooper pairs Surface physics dominated by the bulk properties is attracting much attention. For example, bulk-boundary correspondence predicts topological surface states. Another important context where […]
Direct detection of odd-frequency superconductivity Odd-frequency superconductivity is a dynamical phenomenon. The time-dependence of the anomalous Green function matters. Therefore, a dynamical response is needed to directly detect odd-frequency superconductivity. […]
Kekule spiral order in twisted bilayer graphene Twisted bilayer graphene has attracted a lot of attention due to the presence of correlated insulators proximate to superconductivity. In this talk I […]
Searches for dark matter and exotic astrophysics with networks of quantum sensors. As precision quantum sensors become ubiquitous, it is natural to combine them into networks. I will focus on […]
