Condensate ground states of hardcore bosons induced by an array of impurities
J. Y. Liu-Sun, E. S. Ma, Z. Song
Neither hardcore bosons nor fermions can occupy the same lattice site-state. However, a nearest neighbour interaction may counteract the hardcore effect, resulting in condensate st…

Exact eigenstates with off-diagonal long-range order for interacting bosonic systems
C. H. Zhang, Z. Song
Fermions and hardcore bosons share the same restriction: no more than one particle can occupy a single site in a lattice system. Specifically, in one dimension, two systems can sha…

Emerging topological characterization in non-equilibrium states of quenched Kitaev chains
Y. B. Shi, X. Z. Zhang, Z. Song
Topological characteristics of quantum systems are typically determined by the closing of a gap, while the dynamical quantum phase transition (DQPT) during quantum real-time evolut…
