Mott insulators in moiré transition metal dichalcogenides at fractional fillings: Slave-rotor mean-field theory
Zhenhao Song, Urban F. P. Seifert, Zhu-Xi Luo +1
In this work, we study a slave-rotor mean-field theory of an extended Hubbard model, applicable to transition metal dichalcogenide moiré systems, that captures both the formation o…
Spin-Peierls instability of the U(1) Dirac spin liquid
Urban F. P. Seifert, Josef Willsher, Markus Drescher +2
A complicating factor in the realization and observation of quantum spin liquids in materials is the ubiquitous presence of other degrees of freedom, in particular lattice distorti…
Wegner's Ising gauge spins versus Kitaev's Majorana partons: Mapping and application to anisotropic confinement in spin-orbital liquids
Urban F. P. Seifert, Sergej Moroz
Emergent gauge theories take a prominent role in the description of quantum matter, supporting deconfined phases with topological order and fractionalized excitations. A common con…
Spin-polarons and ferromagnetism in doped dilute Wigner-Mott insulators
Urban F. P. Seifert, Leon Balents
Moiré heterostructures of transition metal dichalcogenides exhibit Mott-insulating behaviour both at half-filling as well as at fractional fillings, where electronic degrees of fre…
