Mixed moment and joint non-vanishing of and -functions
Sayan Ghosh, Pratim Mitra
In this article, we study the mixed-moment problem for the product of central values of two -functions twisted by a Dirichlet character of large conductor . Precisely, for a…
Non-Vanishing of Cubic Twists of -functions
Sayan Ghosh, Pratim Mitra
Let be an irreducible, cuspidal automorphic representation of (), which is tempered only for . Let be a complex number such that…
Basis Adaptive Algorithm for Quantum Many-Body Systems on Quantum Computers
Anutosh Biswas, Sayan Ghosh, Ritajit Majumdar +3
We introduce a Basis Adaptive (BA) algorithm for hybrid quantum-classical simulation of correlated quantum many-body systems. Starting from a small set of physically motivated bits…
A long-range model for the electron-nuclear coupling and two-stage order in TmVO
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 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…
Emergent Quadrupolar Order in the Spin- Kitaev-Heisenberg Model
Manodip Routh, Sayan Ghosh, Jeroen van den Brink +2
Motivated by the largely unexplored domain of multi-polar ordered spin states in the Kitaev-Heisenberg (KH) systems we investigate the ground state dynamics of the spin-$\frac{1}{2…
