In quantum magnetism, Kitaev's honeycomb model is well known for its gapped and gapless spin liquid ground states in which the elementary degrees of freedom fractionalize into Majorana fermions a ${\mathbb{Z}}_{2}$ gauge field. this paper, authors discuss liquids arising three-dimensional Kitaev models show that form metallic which, depending on underlying lattice structure, exhibit Fermi surfaces, nodal lines, or Weyl points.
The fractionalization of quantum numbers in interacting many-body systems is a central motif condensed-matter physics with prominent examples including the electron Hall liquids or emergence magnetic monopoles spin-ice materials. Here, we discuss moments three-dimensional Kitaev models into Majorana fermions (and Z_{2} gauge field) and their emergent collective behavior. We analytically demonstrate that form Weyl superconductor for model on recently synthesized hyperhoneycomb structure...
The observation that laser-induced fluorescence (LIF) spectra of atherosclerotic and normal artery are different has been proposed as the basis for guiding a "smart" laser angioplasty system. purpose this study was to investigate causes difference in LIF. Helium-cadmium (325 nm) recorded from pure samples known constituents including collagen, elastin, calcium, cholesterol, glycosaminoglycans. Similarities between LIF plaque collagen aorta elastin were noted. spectroscopy then performed on...
In the field of frustrated magnetism, Kitaev models provide a unique framework to study phenomena spin fractionalization and emergent lattice gauge theories in two three spatial dimensions. Their ground states are quantum liquids, which can typically be described terms Majorana band structure an ordering underlying $\mathbb{Z}_2$ structure. Here we comprehensive classification "gauge physics" family elementary three-dimensional models, discussing how their thermodynamics state order depends...
This paper describes the development of laser-produced-plasma (LPP) extreme-ultraviolet (EUV) source architecture for advanced lithography applications in high volume manufacturing. EUV is expected to succeed 193nm immersion technology sub-22nm critical layer patterning. In this we discuss most recent results from power testing and debris mitigation on witness samples normal incidence collectors. Subsystem performance will be shown including CO2 drive laser, mitigation, collector coatings,...
Chiral spin liquids (CSLs) are exceptional magnetic states that break time-reversal symmetry without long-range ordering. Here, the authors showcase a family of CSLs in three-dimensional extension Kitaev model on hypernonagon lattice, using quantum Monte Carlo simulations supplemented by variational calculations. Notably, all found to not only but concurrently also number lattice symmetries forming crystalline ordering underlying \ensuremath{\mathbb{Z}}${}_{2}$ gauge structure. It is further...
In standard quantum mechanics, complex numbers are used to describe the wavefunction. Although have proven sufficient predict results of existing experiments, there is no apparent theoretical reason choose them over real or generalizations numbers, i.e. hyper-complex numbers. Experiments performed date that insufficient, but whether not required remains an open question. Quantum theories based on one example a post-quantum theory, which must be put firm experimental foundation. Here we...
This paper describes a frequency-limited derivative technique that has dramatically increased our ability to resolve Fermi-surface discontinuities in 2D ACAR spectra. The performance of the technique, which involves minimal CPU time, is demonstrated with example applications both simulated and real
Research examining display format and highlight validity (Tullis, 1984; Fisher & Tan, 1989) have shown that these factors affect visual search; however, studies been conducted on small, artificial alphanumeric displays.

Automated expert advisors should provide real time information that allows assessment of the advisor's response instead providing explanation facilities add to operator's workload. In system control environments, an automated advisor applies established rules data, arriving at status. The processing data results in being either conserved, reduced, or created. typically reduce create thereby reducing operator a where human retains final control, primary goal is for be able maintain system,...
