Moiré systems have emerged in recent years as a rich platform to study strong correlations. Here, we will propose simple, experimentally feasible setup based on periodically strained graphene that reproduces several key aspects of twisted moiré heterostructures-but without introducing twist. We consider monolayer sheet subject C_{2}-breaking periodic strain-induced pseudomagnetic field with period L_{M}≫a, along scalar potential the same period. This system has almost ideal flat bands...
Graphene bilayers exhibit zero-energy flat bands at a discrete series of magic twist angles. In the absence intra-sublattice inter-layer hopping, states satisfy Dirac equation with non-abelian SU(2) gauge potential that cannot be diagonalized globally. We develop semiclassical WKB approximation scheme for this by introducing dimensionless Planck's constant proportional to angle, solving linearized around AB and BA turning points, connecting Airy function solutions via bulk wavefunctions....

A line-structured laser scanner is widely applied for 3D reconstruction in industrial environments with ubiquitous various luminance, complicated background, diverse objects, and instable lasers. These elements will show up as noise the obtained stripe images. Therefore, basic key point a to accurately extract from noise. This paper proposes an effective extraction procedure two steps. First, novel center method based on geometry information correlation stripe, designed significantly...
Polaritons in two-dimensional (2D) materials have shown their unique capabilities to concentrate light into deep subwavelength scales. Precise control of the excitation and propagation 2D polaritons has remained a central challenge for future on-chip nanophotonic devices circuits. To solve this issue, we exploit Cherenkov radiation, classic physical phenomenon that occurs when charged particle moves at velocity greater than phase medium, low-dimensional material heterostructures. Here,...
Lattice dynamics play a crucial role in the physics of Moir\'e systems. In twisted bilayer graphene (TBG), it was shown that, addition to phonons, there is another set gapless excitations termed Phonons [Phys. Rev. B, 075416, 2019] reflecting lattice at Moire superlattice level. These modes were later suggested be phasons due incommensurate stacking two layers 155426, 2019]. this work, we elucidate equivalence these seemingly distinct perspectives by identifying an underlying symmetry, which...

Several unique topologies are revealed, lead to novel Floquet-Bloch oscillations electron's motion. also discover intraband Zener tunneling beyond adiabatic limit, effectively converts between different topologies. Our results indicate possibility...
Laser triangulation allows non-contact measurement in the third dimension. Due to nonlinearities presented camera and laser sensor, large range distances are quite difficult measure with high precision. In order enhance precision accuracy of based on triangulation, we propose a novel scheme composed four emitters, curve fitting subpixel location algorithm for center detection, linear regression approach Gaussian model calibration. When an object performs 100 mm displacement from closer...
An analytical apparatus with improved recirculating and sampling mechanisms was presented to investigate phase behavior of binary multicomponent systems, which effectively avoided undesirable pressure gradients across the cell serious disturbance equilibrium during procedure. Two one-channel magnetic recirculation pumps were designed built provide better mass transfer between coexisting phases. six-port switching valves used for sampling, quantitative fluid injection, online compositional...
An improved genetic algorithm is proposed in which a diffusing operator designed. Gaussian mutation method applied and its task mainly to perform local search. Connection weights of an artificial neural network are trained on standard XOR problem by using the algorithm. The results show that can both global search efficiently, therefore, it be used train networks alone rather than incorporate other algorithms, such as BP improve training algorithm, so significant simplify efficiency
A space-time crystal is defined as a quantum mechanical system with both spatial and temporal periodicity. Such can be described by the Floquet-Bloch (FB) theory. We first formulate semiclassical theory constructing wave-packet through superposition of FB wave functions derive equations motion electrons subjected to slowly varying external fields (not confused fast-changing Floquet drive), revealing behaviors similar ordinary Bloch but quantities modified in context. Specifically, we study...
Single-walled carbon nanotubes (SWCNTs), due to their outstanding electrical and optical properties, are expected have extensive applications, such as in transparent conductive films ultra-small field-effect transistors (FETs). However, those applications can only be best realized with pure metallic or semiconducting SWCNTs. Hence, identifying separating from SWCNTs as-grown samples crucial. In addition, knowledge of the type an SWCNT is also important for further exploring its new...
Single-walled carbon nanotube (SWNT) has attracted widespread attention for its unique one-dimensional atomic structure and outstanding physical chemical properties. For both fundamental research practical applications, it is critical to figure out the chirality of SWNT because electronic band consequent electrical optical properties are determined by chirality. Here, we found that on an insulating hexagonal boron nitride (h-BN) substrate can be obtained in a quick concise manner through...
