Magnetic structure and component-separated transitions of HoNiSi $_{3}$

R. Tartaglia, F. R. Arantes, C. W. Galdino +7

HoNiSi $_{3}$ is an intermetallic compound characterized by two successive antiferromagnetic transitions at $T_{N 1} = 6.3$ K and $T_{N 2} = 10.4$ K. Here, its zero-field microscopic…

Pressure--enhanced fractional Chern insulators in moiré transition metal dichalcogenides along a magic line

Nicolás Morales-Durán, Jie Wang, Gabriel R. Schleder +5

We show that pressure applied to twisted WSe $_{2}$ can enhance the many-body gap and region of stability of a fractional Chern insulator at filling $ν = 1/3$ . Our results are based on…

Topological Hall effect in CeAlGe

M. M. Piva, J. C. Souza, G. A. Lombardi +4

The Weyl semimetal CeAlGe is a promising material to study nontrivial topologies in real and momentum space due to the presence of a topological magnetic phase. Our results at ambi…

Interplay of structure and magnetism in LuFe4Ge2 tuned by hydrostatic pressure

M. O. Ajeesh, P. Materne, R. D. dos Reis +15

LuFe $_{4}$ Ge $_{2}$ crystallizes in the ZrFe $_{4}$ Si $_{2}$ -type structure, hosting chains of Fe-tetrahedra giving rise to geometric frustration and low-dimensionality. The compound orders a…

Approximate expression for the ground-state energy of the two- and three-dimensional Hubbard model at arbitrary filling obtained from dimensional scaling

Luana N. O. Vilela, Klaus Capelle, Luiz N. Oliveira +1

We generalize the linear discrete dimensional scaling approach for the repulsive Hubbard model to obtain a nonlinear scaling relation that yields accurate approximations to the gro…

Pressure-tuning of bond-directional exchange interactions and magnetic frustration in hyperhoneycomb iridate $β$ - $L i_{2} Ir O_{3}$

L. S. I. Veiga, M. Etter, K. Glazyrin +14

We explore the response of Ir $5 d$ orbitals to pressure in $β$ - $L i_{2} Ir O_{3}$ , a hyperhoneycomb iridate in proximity to a Kitaev quantum spin liquid (QSL) ground state. X-ray…
