Abstract We theoretically investigate the reflected spatial Imbert-Fedorov (IF) shift of transverse-electric (TE)-polarized beam illuminating on a bulk Weyl semimetal (WSM). The spatial IF shift is enhanced significantly at two different frequencies close to the epsilon-near-zero (ENZ) frequency, where large values of reflection coefficients $|r_{\rm pp}| / | r_{\rm ss}|$ are obtained due to the ENZ response induced different rapid increasing trends of $|r_{\rm pp}|$ and $| r_{\rm ss}|$. Particularly, the tunable ENZ effect with tilt degree of Weyl cones and Fermi energy enables the enhanced spatial IF shift at different frequencies. The enhanced spatial IF shift also shows the adjustability of WSM thickness, incident angle and Weyl node separation. Our findings provide easy and available methods to enlarge and adjust the reflected IF shift of TE-polarized light with a WSM.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
