Abstract Quantum phase transitions (QPTs) are usually associated with many-body systems in the thermodynamic limit when their ground states show abrupt changes at zero temperature variation of a parameter Hamiltonian. Recently it has been realized that QPT can also occur system composed only two-level atom and single-mode bosonic field, described by quantum Rabi model (QRM). Here we report an experimental demonstration QRM using 171 Yb + ion Paul trap. We measure spin-up state population...
Symmetries play a crucial role in the classification of topological phases matter. Although recent studies have established powerful framework to search for and classify based on symmetry indicators, there exists large class fragile topology beyond description. The Euler characterizing two-dimensional real wave functions is an archetypal underlying some important properties, such as non-Abelian braiding crossing nodes higher-order topology. However, minimum model topology, insulator...
The spin-boson model is a prototypical for open quantum dynamics. Here we simulate the using chain of trapped ions in which spin coupled to structured reservoir bosonic modes. We engineer spectral density by adjusting ion number, target location, laser detuning phonon sidebands, and number frequency components laser, observe their effects on collapse revival initially encoded information. Our work demonstrates that trap powerful platform simulating dynamics with complicated structures.
This article proposes an improved incremental random vector functional-link network (RVFL) with a compact structure and presents its application to quality prediction of blast furnace (BF) ironmaking processes. Different from the original RVFL, RVFL has no input-output direct links output bias (NLNB) approaches desired by sequentially updating weights fixed hidden neurons. Moreover, it is proved that this NLNB (I-I-RVFL-NLNB) able approximate given continuous function arbitrary small errors...
Abstract To explore if translation-intrinsic features are apparent in other types of bilingualism-influenced constrained language use such as non-native production, this study approaches syntactic and typological properties English translated from Chinese written by native speakers via two cognitively-motivated dependency metrics, viz. mean distance (MDD) direction (DDir). Results show that (both L1 L2) differ the non-constrained a similar way yet to slightly different extent, but not each...
Synthetic dimension is a potent tool in quantum simulation of topological phases matter. Here we propose and demonstrate scheme to simulate an anisotropic Harper-Hofstadter model with controllable magnetic flux on two-leg ladder using the spin motional states single trapped ion. We verify successful this by comparing measured dynamics theoretical predictions under various coupling strength flux, observe chiral motion wave packets as evidence edge modes. develop quench path adiabatically...
Supersymmetry (SUSY) helps solve the hierarchy problem in high-energy physics and provides a natural groundwork for unifying gravity with other fundamental interactions. While being one of most promising frameworks theories beyond Standard Model, its direct experimental evidence nature still remains to be discovered. Here we report realization supersymmetric quantum mechanics (SUSY QM) model, reduction SUSY field theory studying properties, using trapped ion simulator. We demonstrate energy...
Abstract The present study revisits the unique item hypothesis (UIH) from perspective of translation directionality in Chinese–English(C–E) language pair. Phrasal verb (PV) is used as linguistic feature to investigate whether UIH holds true C–E translations and plays a role representation items, based on self-built parallel corpus Lu Xun’s short stories their English done by two L1 L2 translators, reference BNC non-translated reference. It found PVs are significantly over-represented...
Trapped ions are one of the leading platforms in quantum information science. For computing with large circuit depth and simulation long evolution time, it is crucial importance to cool ion crystals at runtime without affecting internal states computational qubits, thus necessity sympathetic cooling. Here, we report multi-ion cooling on a chain using narrow beam focused two adjacent ions, optimize choice according collective oscillation modes chain. We show that, by small fraction effects...
Dissipation is often considered as a detrimental effect in quantum systems for unitary operations. However, it has been shown that suitable dissipation can be useful resources both information and simulation. Here, we propose experimentally simulate dissipative phase transition (DPT) model using single trapped ion with an engineered reservoir. We show the ion's spatial oscillation mode reaches steady state after alternating application of evolution under Rabi Hamiltonian sideband cooling...
Abstract As a “third code”, translational language attracts considerable attention in linguistics research due to its distinctive features. Adopting the quantitative linguistic approach, current study examines features by investigating mean dependency distance (MDD), as well probability distribution of individual distances (DDs) and high-frequency type language. The MDD distributions were tested self-built corpus which contains parallel comparable materials both Chinese-English...
Abstract Extensive studies have described the linguistic features of human translations and verified existence simplification translation universal. However, little has been known about machine translations, although translation, as a unique modality become an integral part practice. This study is intended to test whether universal observed in also holds true for translations. If so, are different significantly from those translations? And does genre affect features? To this end, we built...
The Klein tunneling effect describes the transmission of a relativistic particle with normal incidence through an energy barrier. It has been observed and tested in various electronic, photonic, phononic systems, but its potential guiding filtering classical waves ultrahigh frequency regime not explored. Here, we report realization acoustic nanoelectromechanical metamaterial system operating at gigahertz frequencies. piezoelectric profiles are obtained by transmission-mode microwave...
Topological defects are discontinuities of a system protected by global properties, with wide applications in mathematics and physics. While previous experimental studies mostly focused on their classical it has been predicted that topological can exhibit quantum superposition. Despite the fundamental interest potential understanding symmetry-breaking dynamics phase transitions, its realization still remains challenge. Here, we report observation superposition trapped-ion simulator. By...
