Quetzalcoatlite as a Disorder-Free Platform for Chiral Magnetism and Frustration

Aleksandar Razpopov, P. Peter Stavropoulos, Michael R. Norman +2

The natural mineral quetzalcoatlite ZnCu(TeO)(OH) (AgPbCl) is a structurally ideal kagome magnet, providing a platform for exploring th…

Accessing Few-Layer CrI Magnetoelasticity Through Bulk Single Crystals

J. Arneth, M. Möller, D. A. S. Kaib +9

The persistence of ferromagnetic long-range order in monolayers of the van der Waals semiconductor CrI opens new routes for spintronic applications based on two-dimensional qua…

GHz non-reciprocal optical conductivity in hematite (-)

Peng Rao, Johannes Gröbmeyer, P. Peter Stavropoulos +5

We study the non-reciprocal properties of the iron oxide -FeO (hematite) in the canted easy-plane antiferromagnetic phase, specifically in the GHz to THz frequency range…

Bobkingite, a new coupled sawtooth chain platform

P. Peter Stavropoulos, Aleksandar Razpopov, Harrison LaBollita +3

We investigate the mineral bobkingite, \ce{Cu5(OH)8Cl2(H2O)2}, as a potential realization of the sawtooth chain. Using \textit{ab initio} methods, we estimate the magnetic exchange…

Revealing the microscopic origin of the magnetization plateau in NaNiBiO

Amanda A. Konieczna, P. Peter Stavropoulos, Roser Valentí

Recent experimental studies of the spin-1 honeycomb antiferromagnet NaNiBiO have revealed a pronounced one-third magnetization plateau under applied magnetic fields, hi…

Exact downfolding and its perturbative approximation

Jonas B. Profe, Jakša Vučičević, P. Peter Stavropoulos +3

Solving the many-electron problem, even approximately, is one of the most challenging and simultaneously most important problems in contemporary condensed matter physics with vario…

Microscopic origin of the magnetic interactions and their experimental signatures in altermagnetic LaOMnSe

Laura Garcia-Gassull, Aleksandar Razpopov, Panagiotis Peter Stavropoulos +2

Altermagnets (AM) are a recently introduced type of magnets, with no net magnetization like antiferromagnets, but displaying a non-relativistic Zeeman splitting in reciprocal space…

Altermagnetic splitting of magnons in hematite (-FeO)

Rhea Hoyer, P. Peter Stavropoulos, Aleksandar Razpopov +3

We develop a four-sublattice spin-wave theory for the -wave altermagnet candidate hematite (-FeO), considering both its easy-axis phase below and its weak ferromagnet…

Phonon Dynamics in the Chiral Kitaev Spin Liquid

Susmita Singh, P. Peter Stavropoulos, Natalia B. Perkins

We investigate the effect of a magnetic field on the extended Kitaev spin liquid state through phonon dynamics. Using a constrained fermionic self-consistent mean field method, we…

Complex orders and chirality in the classical Kitaev- model

P. Peter Stavropoulos, Yang Yang, Ioannis Rousochatzakis +1

It is well-recognized that the low-energy physics of many Kitaev materials is governed by two dominant energy scales, the Ising-like Kitaev coupling and the symmetric off-diago…
