3D printed magnets for neutron spin manipulation [PDF]
EPJ Web of Conferences, 2019 Devices for manipulation of the neutron spin are vital for experiments in neutron optics such as neutron interferometry. Here we introduce a new type of such devices which are based on a magnetic material that can be 3D printed in complex shapes. We have

Foundations of Quantum Mechanics
Encyclopedia, 2022 Quantum mechanics is a mathematical formalism that models the dynamics of physical objects. It deals with the elementary constituents of matter (atoms, subatomic and elementary particles) and of radiation.

Gas Damping in Capacitive MEMS Transducers in the Free Molecular Flow Regime
Sensors, 2021 We present a novel analysis of gas damping in capacitive MEMS transducers that is based on a simple analytical model, assisted by Monte-Carlo simulations performed in Molflow+ to obtain an estimate for the geometry dependent gas diffusion time.

Empirically Charting Dynamical Chiral Symmetry Breaking [PDF]
, 2010 We provide a snapshot of recent progress in hadron physics made using QCD's Dyson-Schwinger equations, reviewing the generation of a quark anomalous chromomagnetic moment, which may explain the longstanding puzzle of the $a_1$-$\rho$ mass splitting, and ...

Visual Culture in Quantum Mechanics. Image-based knowledge making in a non-intuitive world
img journal, 2019 According to a large portion of scholars, mainly coming from the fields of theoretical and experimental physics, quantum mechanics is a particularly challenging subject both to be translated into images and to be communicated without an extensive visual ...

Visualisations of Centre Vortices [PDF]
EPJ Web of Conferences, 2020 The centre vortex structure of the vacuum is visualised through the use of novel 3D visualisation techniques. These visualisations allow for a hands-on examination of the centre-vortex matter present in the QCD vacuum, and highlights some of the key ...

Emergent Structure in QCD [PDF]
EPJ Web of Conferences, 2020 The structure of the S U(3) gauge-field vacuum is explored through visualisations of centre vortices and topological charge density. Stereoscopic visualisations highlight interesting features of the vortex vacuum, especially the frequency with which ...

The computational challenge of lattice chiral symmetry - Is it worth the expense? [PDF]
EPJ Web of Conferences, 2020 The origin of the low-lying position of the Roper resonance in the nucleon energy spectrum has been the subject of significant interest for many years, including several investigations using lattice QCD.

RECONSTRUCTING THE AXIAL VOID VELOCITY PROFILE IN BWRs FROM MEASUREMENTS OF THE IN-CORE NEUTRON NOISE [PDF]
EPJ Web of Conferences, 2021 The problem of determining the axial velocity profile from the in-core neutron noise measurements is revisited, with the purpose of developing an objective method for the determination of the void fraction.

Units for Atomic and Subatomic Physics [PDF]
American Journal of Physics, 1965 The consequences are examined of setting ħ = 1 and c = 1, while retaining the electron volt. The system of units thus defined is simple and practical for atomic and subatomic physics. A convention is also suggested which permits any quantity to be expressed by a number near unity. Trial teaching with such units is suggested.
