Fermionization of a strongly-correlated Bose gas

November 2018. The quantum matter team at Institut Polytechnique de Paris has devised a new method to demonstrate the onset of fermionization in a trapped, strongly-correlated Lieb-Liniger (Bose) gas [1]. Using a combination of analytical and numerical calculations, they have shown that the Tan contact, a pivotal quantity in strongly-correlated quantum gases, displays a marked...
