Quantum spin-glass criticality in disordered frustrated dimer magnets
Darshan G. Joshi, Matthias Vojta
The paper investigates the quantum phase transition between a spin‑glass phase and a dimer quantum paramagnet in a disordered triangular‑lattice bilayer Heisenberg model, using bon…

model on a square lattice: From Altermagnet to Columnar antiferromagnet via quantum disordered phase
Subharthi Paul, Darshan G. Joshi
Altermagnetism in the case of local-moment magnets is characterized by zero net magnetization and splitting of opposite chirality magnon bands in the absence of any spin-anisotropi…

Fate of Bosonic Topological Edge Modes in the Presence of Many-Body Interactions
Niclas Heinsdorf, Darshan G. Joshi, Hosho Katsura +1
Many magnetic materials are predicted to exhibit bosonic topological edge modes in their excitation spectra, because of the nontrivial topology of their magnon, triplon, or other q…
