A Hunt for Magnetic Signatures of Hidden-Photon and Axion Dark Matter in the Wilderness

Posted by klaurent Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Ibrahim A. Sulai, Saarik Kalia, Ariel Arza, Itay M. Bloch, Eduardo Castro Muñoz | Summary: Earth can act as a transducer to convert ultralight bosonic dark matter (axions and hidden photons) into an oscillating magnetic field with a characteristic pattern across its surface. Here we describe […]

Hubbard Model on Triangular Lattice: Role of Charge Fluctuations

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Ji-Si Xu, Zheng Zhu, Kai Wu, Zheng-Yu Weng, | Summary: A chiral spin liquid (CSL) phase has been recently reported in the Hubbard model on a triangular lattice at half-filling. It emerges in an intermediate coupling regime, which is sandwiched between a $120^circ$ antiferromagnetic (AFM) phase and […]
