Gauge fermions with flat bands and anomalous transport via chiral modes from breaking gauge symmetry
Xi Luo, Yue Yu
The dispersionless longitudinal photon in Maxwell theory is thought of as a redundant degree of freedom due to the gauge symmetry. We find that when there exist exactly flat bands…
Realization of Massive Relativistic Spin-3/2 Rarita-Schwinger Quasiparticle in Condensed Matter Systems
Feng Tang, Xi Luo, Yongping Du +2
The spin-3/2 elementary particle, known as Rarita-Schwinger (RS) fermion, is described by a vector-spinor field ψ_{μα}, whose number of components is larger than its independent de…
Nonlinear Quantum Hall effects in Rarita-Schwinger gas
Xi Luo, Feng Tang, Xiangang Wan +1
Emergence of higher spin relativistic fermionic materials becomes a new favorite in the study of condensed matter physics. Massive Rarita-Schwinger 3/2-spinor was known owning very…
Hybrid Weyl Semimetal
Fei-Ye Li, Xi Luo, Xi Dai +3
We construct a tight-binding model realizing one pair of Weyl nodes and three distinct Weyl semimetals. In the type-I (type-II) Weyl semimetal, both nodes belong to type-I (type-II…
