A drop in the sea of electrons

Researchers have provided a measurement of interactions between Fermi polarons in an atomically-thin 2D semiconductor, using ultrafast spectroscopy capable of probing complex quantum materials. The identification of both repulsive (long-range)and attra…

Trapping polaritons in an engineered quantum box

Researchers have engineered a quantum box for polaritons in a 2D material, achieving large polariton densities and a partially ‘coherent’ quantum state. New insights from the novel technique could allow researchers to access striking ‘collective’ quant…
