Sign structure of the model and its physical consequences
Understanding the doped Mott insulator is a central challenge in condensed matter physics.
In this work, we first explicitly identify a new sign structure in the tt′-J model on the square …

Hourglasslike spin excitation in a doped Mott insulator
We examine the dynamical magnetic response in a two-component resonating-valence-
bond (RVB) description of the doped Mott insulator. The half-filled antiferromagnetic phase …

Thermal Hall effect and neutral spinons in a doped Mott insulator
ZJ Song, JX Zhang, ZY Weng - Physical Review Research, 2024 - APS
In the pseudogap phase of the cuprate, a thermal Hall response of neutral objects has been
recently detected experimentally, which continuously persists into the antiferromagnetic …

Non-Ioffe-Larkin composition rule and spinon-dictated electric transport in doped Mott insulators
C Chen, JX Zhang, ZJ Song, ZY Weng - arxiv preprint arxiv:2406.15553, 2024 - arxiv.org
The electric resistivity is examined in the constrained Hilbert space of a doped Mott insulator,
which is dictated by a non-Ioffe-Larkin composition rule due to the underlying mutual Chern …

Continuous transition from a Landau quasiparticle to a neutral spinon
We examine a wavefunction ansatz in which a doped hole can experience a quantum
transition from a charge+ e Landau quasiparticle to a neutral spinon as a function of the …
