Atomic nuclei exhibit multiple energy scales simultaneously—ranging from hundreds down to fractions of a megaelectronvolt. A new study demonstrates that these drastically different scales can be ...

Scientists at Goethe University Frankfurt have identified a new way to probe the interior of neutron stars using ...

Full waveform inversion (FWI) is commonly used in seismic exploration to calculate parameters of the medium, such as velocity, from the signal as it passes through the medium. To obtain an accurate ...

2. The Wave Equation If you take a long string and shake one end, you will create a disturbance. Guess what, with that simple shake you've made a wave pulse, which travels along the string.

Conventional one-way wave-equation propagators have been extensively constructed ... Next, we apply a coupled Schulz iteration scheme to the Helmholtz operator to obtain the square-root operator.
