Opis:: The neutron gyromagnetic ratio has been measured relative to that of the $^{199}He$ atom with an uncertainty of 0.8 ppm. We employed an apparatus where ultracold neutrons and mercury atoms are stored in the same volume and report the result $\gamma _{n}/\gamma _{Hg}$ =3.8424574 ( 30 ).

Opis:: An array of 16 laser-pumped scalar Cs magnetometers was part of the neutron electric dipole moment (nEDM) experiment taking data at the Paul Scherrer Institute in 2015 and 2016. It was deployed to measure the gradients of the experiment's magnetic field and to monitor their temporal evolution. The originality of the array lies in its compact design, in which a single near-infrared diode laser drives all magnetometers that are located in a high-vacuum chamber, with a selection of the sensors mounted on a high-voltage electrode. We describe details of the Cs sensors' construction and modes of operation, emphasizing the accuracy and sensitivity of the magnetic-field readout. We present two applications of the magnetometer array directly beneficial to the nEDM experiment: (i) the implementation of a strategy to correct for the drift of the vertical magnetic-field gradient and (ii) a procedure to homogenize the magnetic field. The first reduces the uncertainty of the nEDM result. The second enables transverse neutron spin relaxation times exceeding 1500 s, improving the statistical sensitivity of the nEDM experiment by about 35% and effectively increasing the rate of nEDM data taking by a factor of 1.8.

Opis:: Let $V$ be a finite vertex set and let $(\mathbb{A}, +)$ be a finite abelian group. An $ \mathbb{A} $-labeled and reversible 2-structure defined on $V$ is a function $ g : (V \times V) \backslash \{ (v, v) : v \in V \} \rightarrow \mathbb{A} $ such that for distinct $ u, v \in V, g(u, v) = −g(v, u) $. The set of $ \mathbb{A} $-labeled and reversible 2-structures defined on $V$ is denoted by $ \mathcal{L} (V, \mathbb{A} ) $. Given $g \in \mathcal{L} (V, \mathbb{A}) $, a subset $X$ of $V$ is a clan of $g$ if for any $x, y \in X$ and $ v \in V \backslash X, g(x, v) = g(y, v) $. For example, $ \emptyset $, $V$ and $ \{ v \} $ (for $v \in V $) are clans of $g$, called trivial. An element $g$ of $ \mathcal{L} (V, \mathbb{A}) $ is primitive if $ |V| \ge 3 $ and all the clans of $g$ are trivial. The set of the functions from $V$ to $ \mathbb{A} $ is denoted by $ (V, \mathbb{A} ) $. Given $ g \in \mathcal{L} (V, \mathbb{A} ) $, with each $ s \in (V, \mathbb{A})$ is associated the switch $ g^s $ of $g$ by $s$ defined as follows: given distinct $x, y \in V $, $g^s(x, y) = s(x) + g(x, y) − s(y) $. The switching class of $g$ is $ \{ g^s : s \in \mathcal{S} (V, \mathbb{A} ) \} $. Given a switching class $ \mathfrak{G} \subseteq \mathcal{L} (V, \mathbb{A} ) $ and $ X \subseteq V $, $ \{ g_{ \upharpoonright (X \times X) \backslash \{ (x,x):x \in X \} } : g \in \mathfrak{G} \} $ is a switching class, denoted by $ \mathfrak{G} [X] $. Given a switching class $ \mathfrak{G} \subseteq \mathcal{L} (V, \mathbb{A} ) $, a subset $X$ of $V$ is a clan of $ \mathfrak{G} $ if $X$ is a clan of some $ g \in \mathfrak{G} $. For instance, every $ X \subseteq V $ such that $ min (|X|, |V \backslash X | ) \le 1 $ is a clan of $ \mathfrak{G} $, called trivial. A switching class $ \mathfrak{G} \subseteq \mathcal{L}(V, \mathbb{A} ) $ is primitive if $ |V | \ge 4 $ and all the clans of $ \mathfrak{G} $ are trivial. Given a primitive switching class $ \mathfrak{G} \subseteq \mathcal{L} (V, \mathbb{A} ) $, $ \mathfrak{G} $ is critical if for each $ v in V $, $ \mathfrak{G} − v $ is not primitive. First, we translate the main results on the primitivity of $ \mathbb{A} $-labeled and reversible 2-structures in terms of switching classes. For instance, we prove the following. For a primitive switching class $ \mathfrak{G} \subseteq \mathcal{L}(V, \mathbb{A})$ such that $|V| \ge 8$, there exist $ u, v \in V$ such that $ u \ne v$ and $ \mathfrak{G} [V \backslash \{ u, v \} ]$ is primitive. Second, we characterize the critical switching classes by using some of the critical digraphs described in [Y. Boudabous and P. Ille, Indecomposability graph and critical vertices of an indecomposable graph, Discrete Math. 309 (2009) 2839–2846].
