Theory

We start the discussion by considering the acoustic system in Fig. 1a, which is made of a Kagome lattice distribution of air-filled waveguides. The air domain is illustrated in Fig. 1a-I-II, while the external, rigid frame is shown in…

Model

We consider the phenomenological magnetic energy density of the form^53,57,58

In growing elastic materials, residual stresses in their structure often accumulate when the preferred geometry of the growth process is constrained. As the stresses build, a mechanical instability can occur that reduces the stress while changing…

Conventional geodetic techniques — such as electronic distance measurements, borehole strainmeters, tilt measurements and satellite-based methods — lack the spatiotemporal resolution needed to resolve rapid magma intrusion dynamics, such as…

Fracture geometry by tomography

The study of mixed-mode I + III fractures requires an experimental setup that allows independent stimulation of both modes, while preventing unstable fracture propagation, so that the state of the fracture can…

In this proof-of-principle demonstration, the team loaded around 100 protons into BASE-STEP, a 900-kg Penning-trap system. With the help of two overhead cranes and a trailer, the system was then transported across the hall of the antimatter…
