Real-frequency TPSC+DMFT investigation of the square-lattice Hubbard model
Lei Geng, Jiawei Yan, Philipp Werner
We investigate the two-dimensional Hubbard model using a real-frequency implementation of the TPSC+DMFT approach. This hybrid method combines the nonlocal correlations captured by…
Anomalous photo-induced band renormalization in correlated materials: Case study of TaNiSe
Lei Geng, Xiulan Liu, Jianing Zhang +2
We investigate the anomalous photo-induced band renormalization in correlated materials, exemplified by the case of TaNiSe. The manifestation of this anomaly is characteriz…
Laser-induced electron Fresnel diffraction by XUV pulses at extreme intensity
Lei Geng, Hao Liang, K. Krajewska +2
Ionization of atoms and molecules in laser fields can lead to various interesting interference structures in the photoelectron spectrum. For the case of a super-intense extreme ult…
Some Tests on CPT Invariance
C. Q. Geng, Lei Geng
We first briefly review tests on CPT invariance based on the consequences of the CPT theorem and then present some possible CPT tests due to exotic models in which some of the CPT…
