Chiral Color Ice: Exact Local Handedness Constraints and Möbius Zero Modes in Frustrated Magnets
Péter Kránitz, Yasir Iqbal, Karlo Penc
Local constraints govern the low-energy physics of frustrated matter, but familiar ice-type rules constrain flux-like quantities and are insensitive to handedness. Here we show tha…

Rigorous Anderson-type lower bounds on the ground-state energy of the pyrochlore Heisenberg antiferromagnet
Péter Kránitz, Karlo Penc
We construct rigorous Anderson-type lower bounds on the ground-state energy of the spin- Heisenberg antiferromagnet on the pyrochlore lattice. By formulating and optimizing a hi…

The algebraic spin liquid in the SU(6) Heisenberg model on the kagome lattice
Dániel Vörös, Kránitz Péter, Karlo Penc
We explore the Dirac spin liquid (DSL) as a candidate for the ground state of the Mott insulating phase of fermions with six flavors on the Kagome lattice, particularly focusing on…
