Cleavage-History-Dependent Low-Temperature ARPES Spectra of Charge-Ordered EuAl
Hao Liu, Bo Chen, Chen Zhang +9
Charge ordering in EuAl has been widely discussed in connection with band reconstruction, magnetism, and topological electronic states, yet the microscopic origin of the comple…

Unusual Dual Flat Bands and two-dimensional Dirac-node Arc State in Kagome Metal Ni3In2S2
Bo Liang, Yichen Liu, Jie Pang +36
Kagome materials are at the frontier of condensed matter physics. An ideal kagome lattice features only one geometrically frustrated flat band spanning the entire momentum space an…

Experimental realization of dice-lattice flat band at the Fermi level in layered electride YCl
Songyuan Geng, Xin Wang, Risi Guo +15
Flat electronic bands, where interactions among electrons overwhelm their kinetic energies, hold the promise for exotic correlation physics. The dice lattice has long been theorize…
