p wave Magnetism and Gate-Tunable Edelstein Response in van der Waals Heterostructures
Hanbyul Kim, Chan Bin Bark, Seik Pak +2
Odd-parity magnetism has attracted significant interest for its unconventional spin splitting. However, a concrete microscopic route for its realization remains elusive. In this wo…
Strong interlayer coupling and chiral flat-band cascades in twisted bilayer gratings
Daegwang Choi, Soon-Jae Lee, Seung-Woon Cho +5
From atomic crystals to macroscopic material structures, twisted bilayer systems have emerged as a promising route to control wave phenomena. In few-layer van der Waals (vdW) mater…
Eta-pairing state in flatband lattice: Interband coupling effect on entanglement entropy logarithm
Seik Pak, Hanbyul Kim, Chan Bin Bark +3
The eta-pairing state is the eigenstate of the hypercubic Hubbard model, which exhibits anomalous logarithmic scaling of entanglement entropy. In multi-band systems, eta-pairing ca…
Stacking-dependent topological electronic structures in honeycomb-kagome heterolayers
Chan Bin Bark, Hanbyul Kim, Seik Pak +4
Heterostructures of stacked two-dimensional lattices have shown great promise for engineering novel material properties. As an archetypal example of such a system, the hexagon-shar…
PT-symmetric Non-Hermitian Hopf Metal
Seik Pak, Cheol Hun Yeom, Sonu Verma +1
Hopf insulator is a representative class of three-dimensional topological insulators beyond the standard topological classification methods based on K-theory. In this letter, we di…
