Glassy Relaxation Dynamics in the Two-Dimensional Heavy Fermion Antiferromagnet CeSiI
Kierstin Torres, Joon Young Park, Victoria A. Posey +10
The recent discovery of the van der Waals (vdW) layered heavy fermion antiferromagnetic metal CeSiI offers promising potential for achieving accessible quantum criticality in the t…
Imaging magnetic switching in orthogonally twisted stacks of a van der Waals antiferromagnet
Alexander J Healey, Cheng Tan, Boris Gross +9
Stacking van der Waals magnets holds promise for creating new hybrid materials with properties that do not exist in bulk materials. Here we investigate orthogonally twisted stacks…
Coupling of Electronic Transitions to Ferroelectric Order in a 2D Semiconductor
Chun-Ying Huang, Daniel G. Chica, Zhi-Hao Cui +16
A ferroelectric material often exhibits a soft transvers optical (TO) phonon mode which governs it phase transition. Charge coupling to this ferroelectric soft mode may further med…
Quantum Noise Spectroscopy of Criticality in an Atomically Thin Magnet
Mark E. Ziffer, Francisco Machado, Benedikt Ursprung +20
Dynamic critical fluctuations in magnetic materials encode important information about magnetic ordering in the associated critical exponents. Using nitrogen-vacancy centers in dia…
Frustrated hopping from orbital decoration of a primitive two-dimensional lattice
Aravind Devarakonda, Christie S. Koay, Daniel G. Chica +18
Materials hosting flat electronic bands are a central focus of condensed matter physics as promising venues for novel electronic ground states. Two-dimensional (2D) geometrically f…
