Non-Vanishing of Cubic Twists of $G L_{n} (Q)$ $L$ -functions

Sayan Ghosh, Pratim Mitra

Let $I ¨ $ be an irreducible, cuspidal automorphic representation of $G L_{n} (A_{Q})$ ( $n \geq 3$ ), which is tempered only for $n = 3$ . Let $s$ be a complex number such tha…

A long-range model for the electron-nuclear coupling and two-stage order in TmVO $_{4}$

Sayan Ghosh, Anirudha Menon, Manoranjan Kumar +1

We study an infinite-range coupled electronic-quadrupole and nuclear-spin model for ferro-quadrupolar and nuclear-spin ordering in TmVO $_{4}$ in external magnetic and strain fields.…

Frustrated spin-1/2 Heisenberg model on a Kagome-strip chain: Dimerization and mapping to a spin-orbital Kugel-Khomskii model

Sayan Ghosh, Rajiv R. P. Singh, Manoranjan Kumar

We investigate the quantum phases of a frustrated antiferromagnetic Heisenberg spin-1/2 model Hamiltonian on a Kagome-strip chain (KSC), a one-dimensional analogue of the Kagome la…
