The winding number has been widely used as an invariant for diagnosing topological phases in one-dimensional chiral-symmetric systems. We put forward a real-space representation the number. Remarkably, our method reproduces exactly quantized even presence of disorders that break translation symmetry but preserve chiral symmetry. prove number, defined through twisted boundary condition, and derived previously [Phys. Rev. Lett. 113, 046802 (2014)], are equivalent thermodynamic limit at half...
We study topological features of interacting spin-$\frac{1}{2}$ particles in one-dimensional state-dependent optical lattices. Due to the cotranslational symmetry, we introduce center-of-mass Zak phase with help momentum. There appear bound states composed by two different spin via tuning hopping and interaction strengths. Under symmetric open boundary conditions, edge as a result nontrivial bound-state band, which is protected inversion symmetry. The plays crucial role appearance system...
Abstract Background The potential mechanisms underlying cyber victimization and the resulting psychological physical symptoms remain unclear. Thus, present study investigated whether Internet addiction mediates association between peer (e.g., cyberbullying) symptoms. Furthermore, it was assessed exercise moderates hypothetical mediation.

The interplay between crystalline symmetry and band topology gives rise to unprecedented lower-dimensional boundary states in higher-order topological insulators (HOTIs). However, the measurement of invariants HOTIs remains a significant challenge. Here, we define multipole winding number (MWN) for chiral-symmetric by applying corner twisted condition. MWN, arising from both bulk states, accurately captures bulk-corner correspondence including boundary-obstructed phases. To address...

Beyond the well-known topological band theory for single-particle systems, it is a great challenge to characterize nature of interacting multiparticle quantum systems. Here, we uncover relation between invariants defined through twisted boundary condition (TBC) and center-of-mass (c.m.) momentum state in We find that Berry phase TBC can be equivalently obtained from Wilson loop formulated by c.m. states. As Chern number written as winding phase, consequently prove equivalence numbers via...
The concept of Hilbert space fragmentation (HSF) has recently been put forward as a routine to break quantum ergodicity. Although HSF exists widely in models with dynamical constraints, it is still challenging tune it. Here, we propose scheme the one-dimensional tilted lattice interacting spinless fermions periodically driven tunneling. For weak tunneling strength, dynamics for long range time governed by effective Hamiltonians kinetic which appear density-dependent Through Floquet...
We study the interplay between disorder and topology for localized edge states of light in topological zigzag arrays resonant dielectric nanoparticles. characterize properties by winding number that depends on both angle spacing nanoparticles array. For equal-spacing arrays, system may have two values $\nu=0$ or $1$, it demonstrates localization at edges even presence disorder, being consistent with experimental observations finite-length nanodisk structures. staggered-spacing possesses...
The Chern number is a crucial invariant for characterizing topological features of two-dimensional quantum systems. real-space allows us to extract properties systems without involving translational symmetry, and hence plays an important role in investigating with disorder or impurity. On the other hand, twisted boundary condition (TBC) can also be used define absence symmetry. Based on perturbative nature TBC under appropriate gauges, we derive two formulas (namely, noncommutative Bott...

Abstract We uncover the interaction-induced stable self-localization of few bosons in finite-size disorder-free superlattices. In these nonthermalized multi-particle states, one particles forms a superposition multiple standing waves, so that it provides quasi-random potential to localize other particles. derive effective Hamiltonians for self-localized states and find their energy level spacings obeying Poisson statistics. The spatial distribution localized decays exponentially, which is...

As the basis for generating multi-particle quantum correlations, inter-particle interaction plays a crucial role in collective phenomena, phase transitions, and information processing. It can profoundly alter band structure of many-body systems give rise to exotic topological phenomena. Conventional pumping, which has been well demonstrated driven linear or noninteracting systems, may break down presence strong interaction. However, interplay between topology could also induce emergent...
Abstract The potential energy surfaces for the butoxy radical dissociation into R·+O on six low‐lying electronic states have been determined with combined CASSCF and MR‐CI methods. isomerization reactions between different conformers of 1‐ 2‐butoxy radicals at X̃ B̃ also investigated MP2, B3LYP, non‐radiative decay mechanisms state characterized computed intersections.
