We present a transient absorption setup combining broadband detection over the visible-UV range with high temporal resolution (similar to 20 fs) which is ideally suited to trigger and detect vibrational coherences in different classes of materials. We gene ...
The angular momentum of rotating superfluid droplets originates from quantized vortices and capillary waves, the interplay between which remains to be uncovered. Here, the rotation of isolated submicrometer superfluid He-4 droplets is studied by ultrafast ...
he concept of ranked order probability distribution unveils natural probabilistic interpretations for the kink waves (and hence the solitons) solving higher order dispersive Burgers’ type PDEs. Thanks to this underlying structure, it is possible to propose ...
The discovery of topological phases of matter, initially driven by theoretical advances in quantum condensed matter physics, has been recently extended to classical wave systems, reaching out to a wealth of novel potential applications in signal manipulati ...
Introducing non-local effects to metamaterials increases the complexity of their dispersion relation, which allows carefully designed elastic structures to mimic the peculiar roton behaviour of correlated quantum superfluids. ...
Multistability in Kerr resonators which are driven by continuous or modulated optical waves gives rise to the superposition of distinct nonlinear states, yielding a unique platform for studying complex soliton dynamics. Here, by pumping a crystalline micro ...
Fluorescence sensing is an invaluable research tool in life science and biomedical imaging. Despite its major use and advantages, it mainly remains a tool for in vitro studies since exist fluorophores mainly absorb and emit light in the visible region, in ...
Recent studies showed that a specific design can reduce the impact of water waves on structures, thus limiting the damages. Herein the impact of waves on buildings is addressed, pointing out the influence of orientation on the hydrodynamic process. ...
Tsunamis, dam-break waves and impulse waves are catastrophic phenomena that leave thousands of victims and cause severe infrastructural damage. Understanding the impact that these waves have on structures is therefore necessary to properly dimension buildi ...
We study statistical properties after a sudden episode of wind for water waves propagating in one direction. A wave with random initial conditions is propagated using a forced-damped higher-order nonlinear Schrödinger equation. During the wind episode, the ...
