A single-hole ground state Ansatz for the two-dimensional tJ model has been recently
studied by the variational Monte Carlo (VMC) method. Such a doped hole behaves like a …

It is a great discovery in physics of the twentieth century that the elementary particles in
nature are dictated by gauge forces, characterized by a nonintegrable phase factor that an …

Recent realization of well-controlled quantum simulators of the triangular-lattice Fermi-
Hubbard model, including the triangular optical lattices loaded with ultracold Fermions and …

The mechanism of superconductivity in a purely interacting electron system has been one of
the most challenging issues in condensed matter physics. In the BCS theory, the Landau's …

The ground state of the bipartite tJ model must satisfy a specific sign structure, based on
which the single-hole and two-hole ground state A nsa ̈ tze on honeycomb lattice are …

We study the problem of a single hole in an Ising antiferromagnet and, using the magnon
expansion and analytical methods, determine the expansion coefficients of its wave function …

The tJ model remains an indispensable construct in high-temperature superconductivity
research, bridging the gap between charge dynamics and spin interactions within …

The Fermi surface as a contour of the gapless quasiparticle excitation in momentum space is
studied based on a mean-field theory of the doped Mott insulator, where the underlying …

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 …

We present a phenomenological Green's function to characterize the superconducting and
pseudogap phases of the cuprates based on a microscopic theory of doped Mott insulators …
