2D excitation information by MPS method on infinite helixes
Xing-Yu Zhang, Runze Chi, Yang Liu +1
Understanding the excitation spectrum in two-dimensional quantum many-body systems has long been a challenging task. We present an approach by introducing an excitation ansatz base…
Spectral evidence for Dirac spinons in a kagome lattice antiferromagnet
Zhenyuan Zeng, Chengkang Zhou, Honglin Zhou +10
Emergent quasiparticles with a Dirac dispersion in condensed matter systems can be described by the Dirac equation for relativistic electrons, in analogy with Dirac particles in hi…
Accurate determination of low-energy eigenspectra with multi-target matrix product states
Xuan Li, Zongsheng Zhou, Guanglei Xu +5
Determining the low-energy eigenspectra of quantum many-body systems is a long-standing challenge in physics. In this work, we solve this problem by introducing two novel algorithm…
