The systems withprotected edge modes can be regarded as fractionalized analogues of topologicalinsulators. We show that previous examples of 2D fractional topologicalinsulators are special cases of this general construction. As part of ourderivation, we define the concept of "local Kramers degeneracy" ...
We also obtained a class of complex transparent potentials whose Hamiltonian can be intertwined to a free Hamiltonian. We provide a variety of examples ... ANDRIANOV, A. A.,IOFFE, M. V.,CANNATA, F.,... - 《International Journal of Modern Physics A》 被引量: 370发表: 1999年 First-ord...
In the first part of this review paper, we present some examples of two-dimensional bulk phononic crystals i.e.two-dimensional arrays of inclusions assumed of infinite extent along the three spatial directions. We show that the bandwidth of the forbidden band depends strongly on the nature of ...
The device potential of these 2D ferroelectric materials is further demonstrated using the examples of van der Waals heterostructures of InSe/graphene, exhibiting a tunable Schottky barrier, and InSe/WSe, showing a significant band gap reduction in the combined system. These findings promise to ...
Examples of two kinds of relative permeability curves, the Corey curves and the so-called X-curves [27]. By using the concept of relative permeability, the following equation can be used to define the mass flow in two-phase geothermal systems, here presented for the simple case of one-...
Examples of some highly anticipated flexible smart systems are shown in Fig. 1b. The importance of mobility. Historically, organic, amorphous and metal oxide thin-film transistors (TFTs) have been explored for flexible electronics; however, their low charge mobility (m) has limited their ...

The mixed-state inverse engineering scheme is a control scheme used for engineering the quantum state of a driven open quantum system from an initial steady state to a final steady state. In this paper, we present an analytical study of this scheme appli
spatial directions. As the periodic-boundary Hamiltonian describes the dynamics in the bulk, the theorem relates a bulk property (spectral area) to a boundary one (existence of skin modes). Fig.1shows some schematic examples. The complete proof of the theorem is provided in the Supplementary ...
