Based on the 2017 research confirming that spectral mimicry is theoretically possible, an international team of researchers (USA – Tulane University, US Army Research Laboratory, UMass Boston, Louisiana State University, UK) proposed a new way to make one material behave like another by applying specially designed time-dependent fields such as laser pulse. They derived a field-free, nonlinear equation of motion for controlling the expectation value of an essentially arbitrary observable together with rigorous constraints that determine the limits of controllability. They discuss the experimental feasibility of implementing the control fields generated by this model…read more. TECHNICAL ARTICLE
With a newly proposed spectral mimicry scheme, researchers could make two different materials mimic each other’s spectra—or produce the spectrum of other, more exotic materials. Credit: APS/Carin Cain
