Topological Dirac semimetal is a newly discovered class of materials which has attracted intense attention. This material can be viewed as three-dimensional (3D) analog graphene and linear energy dispersion in bulk, leading to range exotic transport properties. Here we report direct quantum evidence the 3D phase layered $\mathrm{ZrT}{\mathrm{e}}_{5}$ by angular-dependent magnetoresistance measurements under high magnetic fields up 31 T. We observed very clear negative longitudinal induced...
Abstract Owing to the coupling between open Fermi arcs on opposite surfaces, topological Dirac semimetals exhibit a new type of cyclotron orbit in surface states known as Weyl orbit. Here, by lowering carrier density Cd 3 As 2 nanoplates, we observe crossover from multiple-frequency single-frequency Shubnikov–de Haas (SdH) oscillations when subjected out-of-plane magnetic field, indicating dominant role transport. With increase SdH further develop into quantum Hall state with non-vanishing...
While pyrite-type PtBi2 with a face-centered cubic structure has been predicted to be three-dimensional (3D) Dirac semimetal, experimental study of its physical properties remains absent. Here we report the angular-dependent magnetoresistance measurements single crystal under high magnetic fields. We observed extremely large unsaturated (XMR) up (11.2×106)% at T=1.8 K in field 33 T, which is comparable previously reported materials, such as WTe2, LaSb, and NbP. The crystals exhibit an...
Quantum chromodynamics (QCD)---the theory of quarks and gluons---has been studied for decades, but it is yet to be fully understood. A recent example the prediction experimental discovery tetraquarks, which opened a new research field. Crucially, numerous unsolved questions regarding standard model can exclusively addressed by nonperturbative calculations. computers solve problems well-established QCD methods are inapplicable, such as real-time evolution. We take key step in exploring this...

The aim present study was analyze dyskerin hepatocellular carcinoma (HCC) determine its correlation with clinicopathologic features, including patients HCC. Methodology/Principal Findings...
Triply degenerate point (TP) fermions in tungsten-carbide-type materials (e.g., MoP), which represent new topological states of quantum matter, have generated immense interest recently. However, the TPs these are found to be far below Fermi level, leading TP having less contribution low-energy quasiparticle excitations. Here, we theoretically predict existence with points close level trigonal layered PtBi2 by ab initio calculations, and experimentally verify predicted band topology...
We report measurements of magnetic quantum oscillations and specific heat at low temperatures across a field-induced antiferromagnetic critical point (QCP)(B_{c0}\approx50T) the heavy-fermion metal CeRhIn_5. A sharp magnetic-field induced Fermi surface reconstruction is observed inside phase. Our results demonstrate multiple classes QCPs in field-pressure phase diagram this metal, pointing to universal description QCPs. They also suggest that robust superconductivity promoted by...

We propose resolution this puzzle from London penetration...
Code summarization generates brief natural language description given a source code snippet, while retrieval fetches relevant query. Since both tasks aim to model the association between and programming language, recent studies have combined these two improve their performance. However, researchers yet been able effectively leverage intrinsic connection as they train in separate or pipeline manner, which means performance can not be well balanced. In this paper, we propose novel end-to-end...
Abstract Charge density wave (CDW), the periodic modulation of electronic charge density, will open a gap on Fermi surface that commonly leads to decreased or vanishing conductivity. On other hand superconductivity, believed competing order, features results in infinite Here we report superconductivity emerges upon Se doping CDW conductor ZrTe 3 when long range order is gradually suppressed. Superconducting critical temperature T c ( x ) 3− (0 ≤ 0.1) increases up 4 K plateau for 0.04 0.07....

Bug localization automatic localize relevant source files given a natural language description of bug within software project. For large project containing hundreds and thousands files, developers need cost lots time to understand reports generated by quality assurance these buggy files. Traditional methods are heavily depending on the information retrieval technologies which rank similarity between in lexical level. Recently, deep learning based models used extract semantic code with...
Quantum oscillation measurements reveal that in magnetic Weyl semimetals NdAlSi and CeAlSi${}_{0.8}$Ge${}_{0.2}$, the areas of extremal orbits on Fermi surfaces change remarkably with varying temperature; such changes depend local spin configurations magnetic-field directions. The temperature dependence is demonstrated to be a result exchange coupling between localized 4$f$ electrons itinerant 5$d$ electrons.
With the purpose of controlling steady state a dielectric nanosphere levitated within an optical cavity, we study its conditional dynamics under simultaneous sideband cooling and additional time-continuous measurement either output cavity mode or nanosphere's position. We find that average phonon number, purity quantum squeezing steady-states can all be made more non-classical through addition measurement. predict continuous monitoring system, together with Markovian feedback, allows one to...
Abstract Research on two-dimensional transition metal dichalcogenides (TMDs) has grown rapidly over the past several years, from fundamental studies to development of next generation technologies. Recently, it been reported that MX 2 -type PdTe exhibits superconductivity with topological surface state, making this compound a promising candidate for investigating possible superconductivity. However, due multi-band feature most TMDs, magnetoresistance and quantum oscillations these TMDs proves...
Transcription factor Forkhead box protein M1b (FoxM1b) plays an important role during mitotic entry and progression. Our previous studies identified polo-like kinase 1 (PLK1) as a major regulator of FoxM1b. During G2/M transition, PLK1 directly interacts with phosphorylates FoxM1b, resulting in full activation the transactivation capacity Such vital regulatory mechanism is essential for timely However, molecular by which PLK1-mediated phosphorylation enhances transcriptional activity FoxM1b...
