Observation of E8 Particles in an Ising Chain Antiferromagnet
Zhao Zhang, Kirill Amelin, Xiao Wang +9
Near the transverse-field induced quantum critical point of the Ising chain, an exotic dynamic spectrum consisting of exactly eight particles was predicted, which is uniquely descr…
Prime Suspects in a Quantum Ladder
Giuseppe Mussardo, Andrea Trombettoni, Zhao Zhang
In this Letter we set up a suggestive number theory interpretation of a quantum ladder system made of N coupled chains of spin 1/2. Using the hard-core boson representation and a l…
Stationary State Degeneracy of Open Quantum Systems with Non-Abelian Symmetries
Zhao Zhang, Joseph Tindall, Jordi Mur-Petit +2
We study the null space degeneracy of open quantum systems with multiple non-Abelian, strong symmetries. By decomposing the Hilbert space representation of these symmetries into an…
Holographic rainbow networks for colorful Motzkin and Fredkin spin chains
Rafael N. Alexander, Amr Ahmadain, Zhao Zhang +1
We present bulk tensor networks that exactly represent the ground states of a continuous family of one-dimensional frustration-free Hamiltonians. These states, which are known as a…
