Systematic study of multi-magnon binding energies in the FM-AFM $J_{1}$ - $J_{2}$ chain

Satoshi Nishimoto

We present a systematic study of multi-magnon bound states (MBSs) in the spin- $\frac{1}{2}$ FM-AFM $J_{1}$ - $J_{2}$ chain under magnetic fields using the density-matrix renormalization…

Instability of the Haldane Phase: Roles of Charge Fluctuations and Hund's Coupling

Satoshi Nishimoto

We systematically investigate the stability of the symmetry-protected topological (SPT) Haldane phase in spin-1/2 Heisenberg and half-filled Hubbard ladders coupled by ferromagneti…

Polarization-Driven Charge Frustration and Emergent Phases in the One-Dimensional Extended Hubbard Model

Sourabh Saha, Jeroen van den Brink, Manoranjan Kumar +1

Frustration is a key driver of exotic quantum phases, yet its role in charge dynamics remains largely unexplored. We show that charge frustration - induced by electronic polarizati…
