Quantum Many-Body Scars, Magnon-Pair Condensation, and Hilbert Space Fragmentation in an Anisotropic Heisenberg Model
J. Y. Liu-Sun, Z. Song
We investigate a spin- anisotropic Heisenberg model on a lattice consisting of two identical bipartite sublattices. A family of exact eigenstates generated by the restricted s…
Exact interlayer triplet-pairing eigenstates in the extended Hubbard model
F. X. Liu, Z. Song
-pairing symmetry generalizes the pairing mechanisms in superconductivity but is broken in the presence of interlayer interactions. In this work, we extend this approach to trip…
Pairing-induced Bloch oscillations in an interacting Kitaev chain
E. S. Ma, Z. Song
We study the peculiar dynamics of the Kitaev chain induced by nearest-neighbor (NN) interaction. We show that a strong NN interaction suppresses single-particle hopping but enhance…
Boundary-dependent topological degeneracy in an Ising chain
E. S. Ma, Z. Song
The topological degeneracy is a characteristic of quantum phase diagram in an Ising chain with transverse field. We revisit the phase diagram at nonzero temperature of an Ising cha…
Periodic dynamics in an Ising chain with a quadratic transverse field
H. P. Zhang, Z. Song
A quadratic well plays a central role in a wide variety of modern physical theories and applications. In this work, we investigate many-body dynamics in a quadratic well, using an…
Non-Hermitian dynamics of Cooper pair splitter
E. S. Ma, Z. Song
We propose a non-Hermitian model for Cooper pair splitters, in which the process of electron tunneling into electrodes is characterized by non-Hermitian terms. We find that across…
