Fractional vortices in a spin-isotropic spiral spin liquid
Cecilie Glittum, Han Yan, Johannes Reuther
Spiral spin liquids are magnetic states whose classical ground-state manifold consists of planar incommensurate spin spirals with wave vectors lying on a continuous ring or surface…
Reentrant behavior and possible magnetization plateau on the double-trillium langbeinite KNi(SO)
Matías G. Gonzalez, Yurii Skourski, Johannes Reuther +1
KNi(SO) is a member of the langbeinite family, consisting of two intertwined trillium lattices, out of which one is strongly coupled (strong-TL) and the other…
Spin Liquids on the Tetratrillium Lattice
Matías G. Gonzalez, Johannes Reuther
The tetratrillium lattice has recently been proposed as responsible for the dynamical properties observed in the langbeinite compound KNi(SO). Here, we study…
Compact localized fermions and Ising anyons in a chiral spin liquid
Tim Bauer, Johannes Reuther
Quasiparticle hybridization remains a major challenge to realizing and controlling exotic states of matter in existing quantum simulation platforms. We report the absence of hybrid…
Anharmonic Collective Oscillations in Isotropic Spin Systems and their Spectroscopic Signatures
Anna Fancelli, Matías G. Gonzalez, Subhankar Khatua +4
Spin waves are the fundamental excitations in magnetically ordered spin systems and are ubiquitously observed in magnetic materials. However, the standard understanding of spin wav…
Classical fracton spin liquid and Hilbert space fragmentation in a 2D spin- model
Nils Niggemann, Meghadeepa Adhikary, Yannik Schaden-Thillmann +1
Classical U(1) fracton spin liquids feature an extensive ground state degeneracy and follow an effective description in terms of a tensor Gauss' law where charges, so-called fracto…
Gapless fracton quantum spin liquid and emergent photons in a 2D spin-1 model
Nils Niggemann, Meghadeepa Adhikary, Yannik Schaden-Thillmann +1
Gapless fracton quantum spin liquids are exotic phases of matter described by higher-rank U(1) gauge theories which host gapped and immobile fracton matter excitations as well as g…
Phase diagram of the XXZ pyrochlore model from pseudo-Majorana functional renormalization group
Yannik Schaden, Matías G. Gonzalez, Johannes Reuther
We calculate the magnetic phase diagram of the spin- nearest neighbor XXZ pyrochlore model using the pseudo-Majorana functional renormalization group in the temperature flow f…
Fragile spin liquid in three dimensions
Anna Fancelli, R. Flores-Calderón, Owen Benton +3
Motivated by the recent appearance of the trillium lattice in the search for materials hosting spin liquids, we study the ground state of the classical Heisenberg model on its line…
Field-induced spin liquid in the decorated square-kagome antiferromagnet nabokoite KCuTeO(SO)Cl
Matías G. Gonzalez, Yasir Iqbal, Johannes Reuther +1
Quantum antiferromagnets based on the square-kagome lattice are proving to be a fertile platform for realizing nontrivial phenomena in frustrated magnetism. Recently, several decor…
Phase diagram of the antiferromagnetic - spin- pyrochlore Heisenberg model
Imre Hagymási, Nils Niggemann, Johannes Reuther
We study the phase diagram of the antiferromagnetic - Heisenberg model on the pyrochlore lattice with spins at zero and finite temperatures. We use a combination of…
Magnetic properties of the spiral spin liquid and surrounding phases in the square lattice XY model
Matías G. Gonzalez, Anna Fancelli, Han Yan +1
Spiral spin liquids possess a subextensively degenerate ground-state manifold, represented by a continuum of energy minima in reciprocal space. Since a small change of the spiral s…
Temperature flow in pseudo-Majorana functional renormalization for quantum spins
Benedikt Schneider, Johannes Reuther, Matías G. Gonzalez +2
We implement the temperature flow scheme first proposed by Honerkamp and Salmhofer in Phys.~Rev.~B 64, 184516 (2001) into the pseudo-Majorana functional renormalization group metho…
