Ferromagnetic transition in a chiral spin chain
Yuan Xiao, Rimika Jaiswal, Oleg A. Starykh +1
We study the zero-temperature properties of a spin- Heisenberg chain with an additional three-site chiral term of strength . The model is known to be integrable and previou…
Classification and correlation signatures of chiral spin liquids on the pyrochlore lattice
Chunxiao Liu, Leon Balents, Yasir Iqbal
The paper classifies and variationally studies chiral quantum spin liquids on the pyrochlore lattice using fermionic parton constructions and analyzes their symmetry, flux patterns…
Emergent gauge flux in mixed QED with flavor chemical potential: application to magnetized U(1) Dirac spin liquids
Chuang Chen, Urban F. P. Seifert, Kexin Feng +3
We design a lattice model of a "mixed" U(1) gauge field coupled to fermions with a flavor chemical potential and solve it with large-scale determinant quantum Monte Carlo simulatio…
Identifying Instabilities with Quantum Geometry in Flat Band Systems
Jia-Xin Zhang, Wen O. Wang, Leon Balents +1
The absence of a well-defined Fermi surface in flat-band systems challenges the conventional understanding of instabilities toward Landau order based on nesting. We investigate the…
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…
Quantum geometry from the Moyal product: quantum kinetic equation and non-linear response
Takamori Park, Xiaoyang Huang, Lucile Savary +1
We systematically derive the dissipationless quantum kinetic equation for a multi-band free fermionic system with U(1) symmetry. Using the Moyal product formalism, we fully band-di…
