Excitation spectra of quantum matter without quasiparticles II: random - models
Maria Tikhanovskaya, Haoyu Guo, Subir Sachdev +1
We present numerical solutions of the spectral functions of - models with random and all-to-all exchange and global SU() spin rotation symmetry. The solutions are obtained…

Excitation spectra of quantum matter without quasiparticles I: Sachdev-Ye-Kitaev models
Maria Tikhanovskaya, Haoyu Guo, Subir Sachdev +1
We study the low frequency spectra of complex Sachdev-Ye-Kitaev (SYK) models at general densities. The analysis applies also to SU() magnets with random exchange at large . T…
