Emergent one-dimensional Bloch oscillations in coupled Ising layers
E. S. Ma, Z. Song
Bloch oscillations typically arise in periodic systems subjected to a constant force generated by a potential gradient. Here, we study domain-wall dynamics in coupled Ising layers…
Pair Filters in an Extended Hubbard Model at Resonance
Ensuo Ma, Zhi Song
We investigate the dynamics of bound pairs in an extended Hubbard model at resonance. We show that a single fermion and a singlet bound pair possess identical dispersion relations…
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 influence of boundary conditions on bulk properties is generally expected to vanish in the thermodynamic limit. Here we show that this expectation can fail in an open transvers…
Condensate states in Fermi and Bose-Hubbard ladders
F. X. Liu, E. S. Ma, Z. Song
Although neither hardcore bosons nor fermions can occupy the same single-site state, they still obey different statistics, resulting in distinct many-particle quantum states, such…
Hilbert space fragmentation in quantum Ising systems induced by side coupling
E. S. Ma, Z. Song
We study Hilbert space fragmentation and quantum scars in quantum spin systems with Ising interactions. The system consists of two sets of quantum spins, A and B. As the parent sys…
Exceptional nodal rings emerging in spinful Rice-Mele chains
E. S. Ma, Z. Song
The Weyl exceptional nodal lines usually occur in 3D topological semimetals, but also emerge in the parameter space of 1D systems. In this work, we study the impact of dissipation…
