Fate of multipolar physics in double perovskites
Ahmed Rayyan, Xiaoyu Liu, Hae-Young Kee
In a cubic environment, the ground state of spin-orbit coupled ions is a non-Kramers doublet, which hosts quadrupole and octupole moments. A series of osmium do…
Origin of -shifted three-dimensional charge density waves in kagome metal AVSb
Heqiu Li, Xiaoyu Liu, Yong Baek Kim +1
Understanding the nature of charge density wave (CDW) and superconductivity in kagome metal AVSb (A=Cs,Rb,K) is a recent subject of intensive study. Due to the presence of…
Non-Kitaev vs. Kitaev Honeycomb Cobaltates
Xiaoyu Liu, Hae-Young Kee
Recently, honeycomb cobaltates with 3 were proposed to display Kitaev physics despite weak spin-orbit coupling. However, other theoretical and experimental works found leading…
Theoretical analysis of single-ion anisotropy in Mott insulators
Xiaoyu Liu, Derek Churchill, Hae-Young Kee
An effective spin model for Mott insulators is determined by the symmetries involved among magnetic sites, electron fillings, and their interactions. Such a spin Hamiltonian offers…
Higher angular momentum pairings in interorbital shadowed-triplet superconductors: Application to SrRuO
Jonathan Clepkens, Austin W. Lindquist, Xiaoyu Liu +1
Even-parity interorbital spin-triplet pairing emerges as an intriguing candidate in multiorbital superconductors with significant Hund's and spin-orbit coupling. Within such a stat…
Floquet Engineering of Magnetism in Topological Insulator Thin Films
Xiaoyu Liu, Peizhe Tang, Hannes Hübener +3
Dynamic manipulation of magnetism in topological materials is demonstrated here via a Floquet engineering approach using circularly polarized light. Increasing the strength of the…
Role of polyhedron unit in distinct photodynamics of zero-dimensional organic-inorganic hybrid tin halide compounds
Xiaoyu Liu, Yuanyuan Li, Tianyuan Liang +1
The zero-dimensional (0D) metal halides comprise periodically distributed and isolated metal-halide polyhedra, which act as the smallest inorganic quantum systems and can accommoda…
In Situ Phase-Transition Crystallization of All-Inorganic Water-Resistant Exciton-Radiative Heteroepitaxial CsPbBr3-CsPb2Br5 Core-Shell Perovskite Nanocrystals
Tianyuan Liang, Wenjie Liu, Xiaoyu Liu +3
The instability of metal halide perovskites upon exposure to moisture or heat strongly hampers their applications in optoelectronic devices. Here, we report the large-yield synthes…
Evidence for quasi-one-dimensional charge density wave in CuTe by angle-resolved photoemission spectroscopy
Kenan Zhang, Xiaoyu Liu, Haoxiong Zhang +10
We report the electronic structure of CuTe with a high charge density wave (CDW) transition temperature Tc = 335 K by angle-resolved photoemission spectroscopy (ARPES). An anisotro…
