Feshbach hypothesis of high-Tc superconductivity in cuprates
Lukas Homeier, Hannah Lange, Eugene Demler +2
Resonant interactions associated with the emergence of a bound state constitute one of the cornerstones of modern many-body physics, ranging from Kondo physics, BEC-BCS crossover,…
Feshbach resonance in a strongly repulsive bilayer model: a possible scenario for bilayer nickelate superconductors
Hannah Lange, Lukas Homeier, Eugene Demler +3
Since the discovery of superconductivity in cuprate materials, the minimal ingredients for high-T superconductivity have been an outstanding puzzle. Motivated by the recently d…
Pairing dome from an emergent Feshbach resonance in a strongly repulsive bilayer model
Hannah Lange, Lukas Homeier, Eugene Demler +3
A key to understanding unconventional superconductivity lies in unraveling the pairing mechanism of mobile charge carriers in doped antiferromagnets, yielding an effective attracti…
Local noise spectroscopy of Wigner crystals in two-dimensional materials
Pavel E. Dolgirev, Ilya Esterlis, Alexander A. Zibrov +3
We propose to use local electromagnetic noise spectroscopy as a versatile and noninvasive tool to study Wigner crystal phases of strongly-interacting two-dimensional electronic sys…
Kinetic Magnetism in Triangular Moiré Materials
Livio Ciorciaro, Tomasz Smolenski, Ivan Morera +8
Magnetic properties of materials ranging from conventional ferromagnetic metals to strongly correlated materials such as cuprates originate from Coulomb exchange interactions. The…
Terahertz parametric amplification as a reporter of exciton condensate dynamics
Sheikh Rubaiat Ul Haque, Marios H. Michael, Junbo Zhu +10
Condensates are a hallmark of emergence in quantum materials with superconductors and charge density wave as prominent examples. An excitonic insulator (EI) is an intriguing additi…
