ABSTRACT The specific depth‐profiling capabilities of the muonic x‐ray emission spectroscopy (μ‐XES) technique have proved to be effective for examination of the elemental distribution within ancient coins. This ‘layered’ analysis can also be applied to the examination of ancient faience, the production of which can result in distinct layers (glaze ...

Inverse seesaw accompanied by Dirac fermionic dark matter
We present an inverse seesaw mechanism by resorting to a U(1)B−L gauge symmetry. In order to cancel the gauge anomalies, we introduce nine neutral fermions among which six participate in the inverse seesaw, while the other three form a Dirac fermion and ...

Large $$N_\mathrm{f}$$ N f for multiple representations
We present an extension of the large- $$N_\mathrm{f}$$ N f formalism that allows one to study cases with multiple fermion representations. The pole structure in the beta function is traced back to the intrinsic non-abelian nature of the gauge group ...

Under the historical definition of entanglement, namely that encountered in Einstein–Podolski–Rosen (EPR)–type experiments, it is shown that a particular Slater determinant is entangled. Thus a definition which holds that any Slater determinant is unentangled, found in the literature, is inconsistent with the historical definition. A generalization of

Chiral fermions on the lattice [PDF]
The Overlap-Dirac operator provides a lattice regularization of massless vector gauge theories with an exact chiral symmetry. Practical implementations of this operator and recent results in quenched QCD using this Overlap-Dirac operator are reviewed.

Probing and Graph Coloring Techniques for Trace Estimation in Lattice QCD
ABSTRACT The computation of Tr[D−1]$\mathrm{Tr}[D^{-1}]$, where D$D$ is the Wilson–Dirac matrix of Lattice QCD, is a fundamental and computationally demanding task with applications to disconnected hadronic correlation functions. Since D−1$D^{-1}$ is a dense matrix of prohibitive size, its trace cannot be computed exactly, and one must resort to ...

Operator Homology and Cohomology in Clifford Algebras
In recent work, the authors used canonical lowering and raising operators to define Appell systems on Clifford algebras of arbitrary signature. Appell systems can be interpreted as polynomial solutions of generalized heat equations, and in probability ...

Composite fermions and the Fermion–Chern–Simons theory [PDF]
The concept of composite fermions, and the related Fermion-Chern-Simons theory, have been powerful tools for understanding quantum Hall systems with a partially full lowest Landau level. We shall review some of the successes of the Fermion-Chern-Simons theory, as well as some limitations and outstanding issues.

The Anomalously High Boiling Point of Water Revisited
Pairwise interactions between binary hydrides depend mainly on size, not dipole moment. Small hydrides experience less steric repulsion, bringing molecules closer together and strengthening hydrogen bonds, which explains their high boiling points. Typically, boiling points increase with molecular weight because dispersion forces strengthen.
