Prediction of novel two-dimensional Dirac nodal line semimetals in Al2B2 and AlB4 monolayers

Saeid Abedi et al.

Summary: This article reports the prediction of Al2B2 and AlB4 monolayers as new 2D nonmagnetic Dirac nodal line semimetals with several novel features. In Al2B2, there is an interesting nodal line enclosing the K point and crossing the Fermi level, showing significant dispersion, providing a new platform to explore exotic properties in dispersive Dirac nodal lines. For the AlB4 monolayer, evidence is provided for a set of 2D nonmagnetic open type-II nodal lines coexisting with superconductivity at a rather high transition temperature, offering a platform for the realization of novel topological features in the 2D limit.

Fermi surface and mass enhancement in the topological nodal-line semimetal NaAlSi

Shinya Uji et al.

Summary: Quantum oscillations in magnetic torque have been measured to investigate the Fermi surface of the topological nodal-line semimetal NaAlSi with a superconducting transition. The results show the presence of small Fermi surfaces elongated in the kz direction and four oscillation branches. Large mass enhancement factors have been obtained, likely associated with superconductivity.

Cascade of correlated electron states in the kagome superconductor CsV3Sb5

He Zhao et al.

Summary: In a new kagome superconductor CsV3Sb5, temperature-dependent cascade of different symmetry-broken electronic states including tri-directional charge order and V-shaped spectral gap opening are discovered. Additional breaking of the six-fold rotational symmetry and presence of an additional 4a(0) unidirectional charge order through the superconducting transition are observed. The experiments reveal a complex landscape of electronic states on a kagome lattice, with intriguing parallels to high-Tc superconductors and twisted bilayer graphene.

Nature of Unconventional Pairing in the Kagome Superconductors AV3Sb5 (A = K, Rb, Cs)

Xianxin Wu et al.

Summary: The recent discovery of AV(3)Sb(5) has revealed an intriguing arena for exotic Fermi surface instabilities in a kagome metal, with superconductivity near multiple van Hove singularities showing indications of unconventional pairing. The sublattice interference mechanism is crucial in understanding the formation of superconductivity in a kagome metal, with nonlocal Coulomb repulsion, the sublattice profile of the van Hove bands, and the interaction strength being crucial parameters determining the preferred pairing symmetry. Implications for potentially topological surface states are discussed, along with a proposal for additional measurements to determine the nature of superconductivity in AV(3)Sb(5).

Majorana zero modes in impurity-assisted vortex of LiFeAs superconductor

Lingyuan Kong et al.

Summary: Iron-based superconductors are promising platforms for Majorana zero modes, but sample inhomogeneity poses challenges for practical construction of topological qubits. By studying LiFeAs superconductor, researchers discovered Majorana zero modes in impurity-assisted vortices due to tuning of bulk Dirac fermions, offering an ideal material platform for topological quantum computation.

Topological nodal line and superconductivity of highly thermally stable two-dimensional TiB4

Lei Wang et al.

Summary: First-principles calculations were used to study the electronic structures, lattice dynamics, electron-phonon coupling, and superconductivity of TBML and TBBL. Both materials were found to be nodal line semimetals, with varying EPC constants and critical temperatures. Applying strain can enhance the superconductivity of TBBL.

Topological properties of noncentrosymmetric superconductors TIr2B2 (T=Nb, Ta)

Yan Gao et al.

Summary: Two new noncentrosymmetric superconductors, NbIr2B2 and TaIr2B2, were found to be topological Weyl metals in the normal state, with unique nodal structures. With the presence of spin-orbit coupling, they exhibit distinctive Weyl ring structures in addition to Weyl points. These characteristics make them a promising platform to explore three-dimensional topological superconductivity.
