Here, we report a comprehensive single-crystal X-ray diffraction study of CeSiI under high pressures up to 8.3 GPa at room… Theory CeSiI https://arxiv.org/abs/2605.28698v1 https://arxiv.org/abs/2605.28698v1 Wed, 27 May 2026 16:25:17 GMT arXiv: We report neutron, X-ray absorption, and resonant X-ray spectroscopy of magnetic excitations in the new heavy-fermion van-der-Waals superconductor CeSiI. We determined effective Hamiltonians and ground states of crystal electric fields and magnons. Isotropic Heisenberg interactions on a quasi two dimensional lattice… Theory CeSiI https://arxiv.org/abs/2601.18476v2 https://arxiv.org/abs/2601.18476v2 Mon, 26 Jan 2026 13:29:33 GMT arXiv: CeSiI is a newly discovered exfoliable van der Waals (vdW) heavy-fermion metal featured by a long-range antiferromagnetic (AF) order (TN =7.5 K) inside the Kondo coherent state below T* = 50 K. To gain a more profound understanding of the intriguing physics of this material and to uncover novel phenomena driven by… Theory CeSiI
