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.…
Emergent quasi-particles of spin-1 trimer chain
Manodip Routh, Anutosh Biswas, Manoranjan Kumar
The recent experimental realization of emergent quasi-particles, such as spinons, doublons, and quartons, in a spin- trimer chain has spurred new interest in low dimensional m…
Predicting Fractionalized Multi-Spin Excitations in Resonant Inelastic X-ray Spectra of Frustrated Spin-1/2 Trimer Chains
Prabhakar, Subhajyoti Pal, Umesh Kumar +2
We theoretically investigate the resonant inelastic X-ray scattering (RIXS) spectra in a quasi-1D chain of weakly coupled frustrated spin-1/2 trimers, as realized in NaCu$_{3…
Frustrated spin-1/2 Heisenberg model on a Kagome-strip chain: Dimerization and mapping to a spin-orbital Kugel-Khomskii model
Sayan Ghosh, Rajiv R. P. Singh, Manoranjan Kumar
We investigate the quantum phases of a frustrated antiferromagnetic Heisenberg spin-1/2 model Hamiltonian on a Kagome-strip chain (KSC), a one-dimensional analogue of the Kagome la…
Inter-chain Interactions, Multi-magnon condensation and Strain effect in chain compound NaVOPO
Manoj Gupta, Manodip Routh, Manoranjan Kumar +1
Employing first-principles modelling and many-body methods, the magnetic properties of spin-1/2 chain compound NaVOPO are explored. The extensive first-principles calculations…
Emergent Quadrupolar Order in the Spin- Kitaev-Heisenberg Model
Manodip Routh, Sayan Ghosh, Jeroen van den Brink +2
Motivated by the largely unexplored domain of multi-polar ordered spin states in the Kitaev-Heisenberg (KH) systems we investigate the ground state dynamics of the spin-$\frac{1}{2…
