Microscopic resonant-shell mechanism for slow Liouvillian sectors in an open correlated lattice
X. Z. Zhang
We develop a microscopic theory for how slow Liouvillian sectors are selected in an open correlated lattice. The starting point is not a postulated non-Hermitian band, but a local…
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…
Steady off-diagonal long-range order state in a half-filled dimerized Hubbard chain induced by a resonant pulsed field
X. Z. Zhang, Z. Song
We show that a resonant pulsed field can induce a steady superconducting state even in the deep Mott insulating phase of the dimerized Hubbard model. The superconductivity found he…
Insulating-to-conducting state transition in the bilayer Hubbard model induced by a perpendicular quench field
X. Z. Zhang, Z. Song
A many-body quantum system with varying parameters can exhibit two distinct quantum states within the same energy shell. This allows for a dynamic transition from the ground state…
Field induced conducting state in Mott insulator
X. Z. Zhang, Z. Song
Electron--electron repulsion, on the one hand, can result in bound pair, which has heavy effective mass. On the other hand, it is also the cause of Mott insulator. We study the eff…
