We have studied the ground state properties of Hubbard model on long six-leg square
cylinders with doped hole concentration 5.55%≤ δ≤ 12.5% using density-matrix …

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 …

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 …

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 …

Optical measurements in doped Mott insulators have discovered the emergence of spectral
weights at mid-infrared (MIR) upon chemical doping and photodoping. MIR weights may …

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 …

A hole injected into a Mott insulator will gain an internal structure as recently identified by
exact numerics, which is characterized by a nontrivial quantum number whose nature is of …

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 …

We use a convolutional restricted Boltzmann machine (CRBM) neural network to construct a
variational wave function (WF) for the Hubbard model on a square lattice and study it using …
