Photonic spin-Hall effect as a probe for time-reversal-symmetry broken band topological phases

Deblina Samanta, Darshan G. Joshi

When a plane polarized Gaussian beam of light is incident on a surface, upon reflection it splits into right and left circularly polarized beams that are spatially separated in the…

Quantum spin-glass criticality in disordered frustrated dimer magnets

Darshan G. Joshi, Matthias Vojta

We study quantum phase transitions of Mott insulators between spin-glass and featureless paramagnetic phases. Specifically, we consider a triangular-lattice bilayer Heisenberg mode…

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…

Spin density wave, Fermi liquid, and fractionalized phases in a theory of antiferromagnetic metals using paramagnons and bosonic spinons

Alexander Nikolaenko, Jonas von Milczewski, Darshan G. Joshi +1

The pseudogap metal phase of the hole-doped cuprates can be described by small Fermi surfaces of electron-like quasiparticles, which enclose a volume violating the Luttinger relati…

Superconductivity of non-Fermi liquids described by Sachdev-Ye-Kitaev models

Chenyuan Li, Subir Sachdev, Darshan G. Joshi

We investigate models of electrons in the Sachdev-Ye-Kitaev class with random and all-to-all electron hopping, electron spin exchange, and Cooper-pair hopping. An attractive on-sit…
