Photonic gauge potentials, including scalar and vector ones, play fundamental roles in emulating photonic topological effects for enabling intriguing light transport dynamics. While previous studies mainly focus on manipulating propagation uniformly distributed here we create a series of gauge-potential interfaces with different orientations nonuniform discrete-time quantum walk demonstrate various reconfigurable temporal-refraction effects. We show that lattice-site interface the potential...
Experimental demonstration of tunable temporal Goos-Hänchen shift (GHS) in synthetic discrete-time heterolattices with scalar and vector gauge potentials is reported. By using Heaviside-function modulation two fiber loops, we create a sharp gauge-potential interface observe GHS for total internal reflection (TIR), which manifests as time delay rather than spatial shift. The TIR occurs the incident mode falls into band gap transmitted region shifting by potential. We find that both potential...
Dynamic localization (DL) of photons, i.e., the light-motion cancellation effect arising from lattice's quasi-energy band collapse under a synthetic ac-electric-field, provides powerful and alternative mechanism to Anderson for coherent light confinement. So far only low-order DLs, corresponding weak ac-fields, have been demonstrated using curved-waveguide lattices where waveguide's bending curvature plays role ac-field as required in original Dunlap-Kenkre model DL. However, inevitable...
Landau-Zener tunneling (LZT), i.e., the nonadiabatic transition under strong parameter driving in multilevel systems, is ubiquitous physics, providing a powerful tool for coherent wave control both quantum and classical systems. While previous works mainly focus on LZT between two energy bands time-invariant crystals, here, we construct synthetic time-periodic temporal lattices from coupled fiber loops demonstrate dc- ac-driven LZTs periodic Floquet bands. We show that display distinctive...
Abstract Refraction is a basic beam bending effect at two media’s interface. While traditional studies focus on stationary boundaries, moving boundaries or potentials could enable new laws of refractions. Meanwhile, discretization plays pivotal role in refraction owing to Galilean invariance breaking principle discrete-wave mechanics, making highly moving-speed dependent. Here, by harnessing synthetic temporal lattice fiber-loop circuit, we observe discrete time gauge-potential barrier. We...
Super-Bloch oscillations (SBOs) are amplified versions of direct current (dc)-driving Bloch realized under the detuned dc- and alternating (ac)-driving electric fields. A unique feature SBOs is coherent oscillation inhibition via ac-driving renormalization effect, which dubbed as collapse SBOs. However, previous experimental studies on have only been limited to weak regime, has not observed. Here, by harnessing a synthetic temporal lattice in fiber-loop systems, we push ac-field into...
Abstract Dynamic localization (DL) refers to a wavefunction confinement effect of electrons in periodic lattices under an ac electric field driving. Recent studies have transplanted DLs from electronic photonic systems using periodically curved waveguide lattices, where the is mimicked by waveguide's bending curvature. However, due severe limitations losses and poor tunability for highly curved, arbitrarily shaped waveguides, present mainly focus on DL simplest sinusoidal‐wave driving; its...
Think tanks can leverage global influence to manifest the soft power of their home countries. International social media is a useful channel for Chinese think spread messages abroad and enhance influence. In this study, we examine tank index report released by University Pennsylvania's Tanks Civil Societies Program (TTCSP). Through comparative analysis content analysis, study analyzes differences between American tanks’ usage presence on Twitter (now called X). Compared with tanks, have much...

Nowadays, a government needs to get the support of public, and it can stand as only if gets trust attention public. Therefore, keep in touch with opinions citizens. Almost everyone uses online social networks like Facebook Twitter up date their daily events. Their emotions, on government, favorite topics trends (movies, food, animals, etc.), things going minds are often displayed media platforms. The main objective this paper is design deploy crawler system based microservices architecture...
Lifecasting is a business model conducted in online social media contexts, wherein site owners produce content that intended to be interesting and even financially compelling an audience of like-minded individuals who participate as both viewers collaborative producers on the topic focus. Largely practiced by young Chinese techno-entrepreneurs, demonstrates how knowledge combined with entrepreneurial spirt marketing sensibilities related promotion Internet can turn into promising careers for...
Prior research on privacy protective behaviors has found that online users irrationally trade protection for convenience, and so act against their own preferences. The present article uses expectancy-confirmation theory (ECT) models to explain the continuance behavioral intentions of toward privacy-protection practices. It redefines convenience highlight human involved in various stages implementing practices processes. results show earlier practice experiences impact as well future users,...
