Anomalous spin-lattice coupling in a 2D antiferromagnetic semiconductor revealed by surface acoustic Rayleigh waves
Zahra Ebrahim Nataj, Md. Sabbir Hossen Bijoy, Vladislav Korostelev +5
Magnetic order in van der Waals magnets can strongly influence their lattice dynamics, yet how this interaction manifests across different phonon length scales remains unclear. Opt…

Quantum Spin Singlet and Classical Néel-Ordered Ground States in MoX3 (X = I, Br) Spin-3/2 Dimerized Antiferromagnetic Chain Crystals
Jordan Teeter, Topojit Debnath, Harshil Goyal +8
We report that MoX3 (X = I, Br) are rare van der Waals materials that exhibit signatures of both quantum spin chains with a spin singlet ground state and classical Neel order. Bulk…

A Quieter State of Charge -- Ultra-Low-Noise Collective Current in Charge-Density-Wave Nanowires
Subhajit Ghosh, Nicholas Sesing, Tina Salguero +3
Electronic flicker noise limits phase stability in communication systems, reduces the sensitivity and selectivity of sensors, and degrades coherence in quantum devices. There is a…
