Magneto-Optical Sensing of the Pressure Driven Magnetic Ground States in Bulk CrSBr Open
Competition between exchange interactions and magnetocrystalline anisotropy may bring new magnetic states that are of great current interest. An applied hydrostatic pressure can further be used to tune their balance. In this work, we inves…

Spin-defect characteristics of single sulfur vacancies in monolayer MoS2 Open
Single spin-defects in 2D transition-metal dichalcogenides are natural spin-photon interfaces for quantum applications. Here we report high-field magneto-photoluminescence spectroscopy from three emission lines (Q1, Q2, and Q*) of He-ion i…

Raman scattering signatures of the strong spin-phonon coupling in the bulk magnetic van der Waals material CrSBr Open
Magnetic excitations in layered magnetic materials that can be thinned down the two-dimensional (2D) monolayer limit are of high interest from a fundamental point of view and for applications perspectives. Raman scattering has played a cru…

High pressure tuning of magnon-polarons in the layered antiferromagnet FePS$_3$ Open
Magnetic layered materials have emerged recently as promising systems to introduce magnetism in structures based on two-dimensional (2D) materials and to investigate exotic magnetic ground states in the 2D limit. In this work, we apply hig…

Efficient single photon emission from a high-purity hexagonal boron nitride crystal Open
Among a variety of layered materials used as building blocks in van der Waals\nheterostructures, hexagonal boron nitride (hBN) appears as an ideal platform\nfor hosting optically-active defects owing to its large bandgap ($\\sim 6$ eV).\nH…
