The combination of geometric frustration, extended hopping, spin-orbit coupling, and a disordered magnetic ground state make NaRuO$_{2}$ an attractive Heisenberg-Kitaev candidate material. Historically, NaRuO$_2$ has been challenging material to produce, even in polycrystalline form. Here we present synthetic efforts that identify propensity for Na$_\text{Ru}$ defects form NaRuO$_2$, revealing ...

Novel phenomena in magnetically-intercalated graphite has been a subject of much research, pioneered and promoted by M.~S. G.~Dresselhaus many others the 1980s. Among most enigmatic findings that era was dramatic, roller-coaster-like behavior magnetoresistivity EuC$_6$ compound, which magnetic Eu$^{2+}$ ions form triangular lattice is commensurate to honeycomb planes. In this study, we provide ...

We study the existence of diagonal representatives in each equivalence class representation matrices boundary conditions $SU(n)$ or $U(n)$ gauge theories compactified on orbifolds $T^2/{\mathbb Z}_N$ ($N = 2, 3, 4, 6$). suppose that theory has a global $G' U(n)$ symmetry. Using constraints, unitary transformations and transformations, we examine whether can simultaneously become not. show at le...

Two-dimensional honeycomb ferromagnets offer the unprecedented opportunity to study interactions between collective modes that in standard bulk do not cross paths. Indeed, they harbor an optical spin-wave branch, i.e. a spin wave which disperses weakly near Brillouin zone center. When doped with free carriers, also host typical gapless plasmonic mode of 2D itinerant electron/hole systems. plasm...

We studied the magnetic properties of YCu$_3$(OH)$_6$Br$_2$[Br$_{1-x}$(OH)$_{x}$] ($x$ = 0.33), where Cu$^{2+}$ ions form two-dimensional kagome layers. There is no order down to 50 mK while Curie-Weiss temperature on -100 K. At zero field, low-temperature specific heat shows a $T^2$ dependence. Above 2 T, linear dependence term in emerges, and value $\gamma C/T$ increases linearly with field. ...

We construct local generalizations of 3-state Potts models with exotic critical points. analytically show that these are described by non-diagonal modular invariant partition functions products $Z_3$ parafermion or $u(1)_6$ conformal field theories (CFTs). These correspond either to non-trivial permutation invariants block diagonal invariants, one can understand in terms anyon condensation. In ...

This paper investigates the relation between colored HOMFLY-PT and Kauffman homology, $${{\,\mathrm{SO}\,}}(N)$$ quantum 6j-symbols, (a, t)-deformed $$F_K$$ . First, we present a simple rule of grading change which allows us to obtain [r]-colored quadruply graded homology from $$[r^2]$$ -colored for thin knots. stems isomorphism representations $$(\mathfrak {so}_6,[r]) \cong (\mathfrak {sl}_4,[...

We use x-ray spectroscopy at Ir L$_3$/L$_2$ absorption edge to study powder samples of the intercalated honeycomb magnet Ag$_3$LiIr$_2$O$_6$. Based on and resonant inelastic scattering measurements, exact diagonalization calculations including next-neighbour Ir-Ir electron hoping integrals, we argue that intercalation Ag atoms results in a nearly itinerant electronic structure with enhanced Ir-...

Speed of sound measurements are currently the utmost importance for development thermodynamic models fluids. A need accurate was identified siloxanes, because their use as working fluid in organic Rankine cycle power systems and scientific interest non ideal classical gas dynamics. The initiative designing realizing a novel acoustic resonator capable performing speed dense vapors at temperature...
