We review exact numerical results for one-dimensional quantum systems with half-filled
bands. The topics covered include Peierls transitions in Holstein, Fröhlich, Su-Schrieffer …

TaTe4, a metallic charge-density wave (CDW) material discovered decades ago, has
attracted renewed attention due to its rich interesting properties, such as pressure-induced …

Determining the electronic ground state of a one-dimensional system is crucial to
understanding the underlying physics of electronic behavior. Here, we demonstrate the …

Including the previously ignored dispersion of phonons we revisit the metal-insulator
transition problem in one-dimensional electron-phonon systems on the basis of a modified …

Fractons are a type of emergent quasiparticle that cannot move freely in isolation, but can
easily move in bound pairs. Similar phenomenology is found in boson-affected hop** …

We use infinite matrix-product-state techniques to study the time evolution of the charge-
density-wave (CDW) order after a quench or a light pulse in a fundamental fermion-boson …

Abstract (Quasi-) one-dimensional systems exhibit various fascinating properties such as
Luttinger liquid behavior, Peierls transition, novel topological phases, and the …

We study the ground state of the one-dimensional extended Hubbard model at half filling
using the entanglement entropy calculated by density matrix renormalization-group …

We show that coupling to vibrational degrees of freedom can drive a semimetal excitonic-
insulator quantum phase transition in a one-dimensional two-band fc-electron system at …

We reexamine the nature of the metallic phase of the one-dimensional half-filled Holstein
model of spinless fermions. To this end, we determine the Tomonaga-Luttinger–liquid …
