Anomalous photo-induced band renormalization in correlated materials: Case study of Ta${}_2$NiSe${}_5$

Lei Geng, Xiulan Liu, Jianing Zhang +2

We investigate the anomalous photo-induced band renormalization in correlated materials, exemplified by the case of Ta${}_2$NiSe${}_5$. The manifestation of this anomaly is characteriz…
