Anyonic molecules through the trion looking glass
Hao-Ran Cui, Vladimir Calvera, Umang Mehta +1
Motivated by recent optical measurements in twisted MoTe homobilayers, we numerically study the binding of itinerant anyons to ordinary electronic bound states. Using a minimal…
Magnon-Mediated Superconductivity in a 2D Itinerant Ferromagnet with Weak Easy-plane Magnetic Anisotropy
Vladimir Calvera, Heqiu Li, Yijie Wang +2
Motivated by recent observations of superconductivity in a quarter-metal state of spin- and valley- polarized graphene multilayers, we investigate pairing within a ferromagnetic ph…

Symmetry-determined generalized ferromagnetism in multi-valley electron fluids
Vladimir Calvera, Erez Berg, Steven A. Kivelson
Quantum electronic fluids with spin and valley degrees of freedom have a correlation driven tendency to flavor polarization (generalized ferromagnetism). To first order in the long…

The properties of a two-dimensional electron gas (2DEG) in a semiconductor host with two valleys related by an underlying rotational symmetry are studied using Hartree-Fock (…
Anomalous Landau level gaps near magnetic transitions in monolayer WSe
Benjamin A. Foutty, Vladimir Calvera, Zhaoyu Han +7
First-order phase transitions produce abrupt changes to the character of both ground and excited electronic states. Here we conduct electronic compressibility measurements to map t…
Characterization and classification of interacting (2+1)D topological crystalline insulators with orientation-preserving wallpaper groups
Naren Manjunath, Vladimir Calvera, Maissam Barkeshli
While free fermion topological crystalline insulators have been largely classified, the analogous problem in the strongly interacting case has been only partially solved. In this p…
