Realization of Quantum Dipoles in Triangular Lattice Crystal Ba3Yb(BO3)3
Rabindranath Bag, Matthew Ennis, Chunxiao Liu +5
We investigate the thermodynamic properties of the ytterbium-based triangular lattice compound Ba3Yb(BO3)3. The results demonstrate the absence of any long-range ordering down to 5…
Ultrafast optical excitation of magnetic dynamics in van der Waals magnets: Coherent magnons and BKT dynamics in NiPS
Urban F. P. Seifert, Mengxing Ye, Leon Balents
Optical pump-probe experiments carried out in the time domain reveal both the intrinsic low energy dynamics and its connections to higher energy excitations in correlated electron…
The free energy of twisting spins in MnSn
Xiaokang Li, Shan Jiang, Qingkai Meng +4
The magnetic free energy is usually quadratic in magnetic field and depends on the mutual orientation of the magnetic field and the crystalline axes. Tiny in magnitude, this magnet…
Symmetric and spin liquids on the pyrochlore lattice
Chunxiao Liu, Gábor B. Halász, Leon Balents
The geometrically frustrated 3D pyrochlore lattice has been long predicted to host a quantum spin liquid, an intrinsic long-range entangled state with fractionalized excitations. T…
Rotation symmetry breaking in the normal state of a kagome superconductor KV3Sb5
Hong Li, He Zhao, Brenden R. Ortiz +6
Recently discovered kagome superconductors AV3Sb5 (A=K, Rb, Cs) provide a fresh opportunity to realize and study correlation-driven electronic phenomena on a kagome lattice. The ob…
Electronic instabilities of kagome metals: saddle points and Landau theory
Takamori Park, Mengxing Ye, Leon Balents
We study electronic instabilities of a kagome metal with a Fermi energy close to saddle points at the hexagonal Brillouin zone face centers. Using parquet renormalization group, we…
