Basis Adaptive Algorithm for Quantum Many-Body Systems on Quantum Computers
Anutosh Biswas, Sayan Ghosh, Ritajit Majumdar +3
The paper proposes a Basis Adaptive algorithm that combines quantum sampling with classical diagonalization to compute ground‑state properties of correlated many‑body systems while…
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…
