Quantum Hall Ferromagnetism in a Cavity Vacuum
Ceren B. Dag, Luis Brey, Ganpathy Murthy +1
We uncover a continuous phase transition in a quantum Hall ferromagnet (QHF) at filling factor , driven by vacuum fluctuations of a cavity. Our analysis starts with a Landau l…
Signatures of the Quantum Geometric Dipole of Interlayer Excitons in Counterflow Conductivity
Fanuel I. Mendez, Luis Brey, H. A. Fertig
Collective excitations of many-body electron systems can carry internal structure, supporting novel quantum geometric and topological properties. Among these are a quantum geometri…
Umklapp-Enhanced Interlayer Valley Drag in Moiré Bilayers
Ritajit Kundu, Mandar M. Deshmukh, Herbert A. Fertig +1
Van der Waals materials may be combined to form moiré patterns that are effectively crystal lattices. These systems are unique in that their in-plane unit cell sizes may be orders…
Quantum simulation of the Haldane phase using open shell molecules
Suman Aich, Ceren B. Dag, H. A. Fertig +2
Dipolar molecules in optical traps are a versatile platform for studying many-body phases of quantum matter in the presence of strong and long-range interactions. The dipolar inter…
Quantum Band Structure and Topology in One Dimensional Modulated Plasmonic Crystal
Luis Brey, H. A. Fertig
Band structures of electrons in a periodic potential are well-known to host topologies that impact their behaviors at edges and interfaces. The concept however is more general than…
Impact of a Lifshitz Transition on the onset of spontaneous coherence
Adam Eaton, Dibya Mukherjee, Herbert Fertig
Lifshitz transitions are topological transitions of a Fermi surface, whose signatures typically appear in the conduction properties of a host metal. Here, we demonstrate, using an…
