Altermagnetism produces pair emission and absorption from dark excitons and magnons in LaOMnSe
Birender Singh, Xian Xu, Sabrina R. Hatt +21
Altermagnets' (AMs) non-relativistic spin splitting enables novel states, spintronic and magneto-optical devices, though their optical signatures remain elusive. Here, we report ex…
Generative modelling powered by room-temperature polariton condensates
Yuan Wang, Marcin Muszynski, Avinash Dash +3
Generative modelling requires efficient stochastic nonlinear transformations and physical platforms that can naturally realise them. We experimentally demonstrate that nonlinear op…
Bulk and surface excitons in the van der Waals magnet CrSBr: Magneto-optical studies to 55 tesla
Junho Choi, Yihyun Moon, Doohyeon Lee +4
In thin layers of the 2D magnetic semiconductor CrSBr, very recent studies identified two distinct band-edge optical resonances, believed to arise from distinguishable bulk and sur…
Microwave-to-optical transduction using magnon-exciton coupling in a layered antiferromagnet
Pratap Chandra Adak, Iris McDaniel, Suvodeep Paul +12
Coherent interfaces between microwave-frequency quantum systems and low-loss optical links are essential for quantum networks. However, existing microwave-optical transducers often…
Optical Modulation Due to Energy Exchange Between Photonic and Exciton Modes in the Intermediate Coupling Regime
Evripidis Michail, Sander A. Mann, Kamyar Rashidi +4
Actively tunable photonic devices are vital for next-generation optoelectronics requiring rapid switching and high bandwidth. Although organic optoelectronic devices have found wid…
