In low-dimensional systems, theory predicts that even weak quenched disorder can round the thermodynamic discontinuities associated with a first-order phase transition. Here, we employ time-domain terahertz spectroscopy to investigate the quasi-two-dimensional… Theory Experiment Nb₃Cl₈, Nb₃Br₈, Nb₃I₈ https://arxiv.org/abs/2607.00997v1 https://arxiv.org/abs/2607.00997v1 Wed, 01 Jul 2026 14:35:16 GMT arXiv: The magnetoelectric coupling in compensated magnets enables stray-field-free manipulation of spin-splitting, holding great promise for spintronics, but inherently hindered by the symmetry mismatch between spatial-inversion-broken ferroelectricity and time-reversal-broken spin states. Here, based on a symmetry-decoupled… Theory Nb₃Cl₈, Nb₃Br₈, Nb₃I₈ https://arxiv.org/abs/2606.10741v1 https://arxiv.org/abs/2606.10741v1 Tue, 09 Jun 2026 11:52:12 GMT arXiv: Strongly correlated two-dimensional systems provide compelling platforms for investigating exotic quantum phenomena. Niobium chloride (Nb₃Cl₈), a single-band Mott insulator, exhibits a remarkable out-of-plane polarization in its topmost layer that oscillates with layer parity, manifesting as an odd-even effect.

Theoretically, quantum effects from exchange scattering between electron-hole pairs significantly modulate exciton dispersion. Here, we report the direct observation of dimensionality-dependent exciton dispersion in a single-band Mott insulator… Theory Nb₃Cl₈, Nb₃Br₈, Nb₃I₈ https://arxiv.org/abs/2506.08730v2 https://arxiv.org/abs/2506.08730v2 Tue, 10 Jun 2025 12:27:32 GMT arXiv: The kagome lattice provides a playground to explore novel correlated quantum states due to the presence of flat bands in its electronic structure. Recently discovered layered kagome compound Nb3Cl8 has been proposed as a Mott insulator coming from the half-filled flat band.
