Abstract:
Richard Feynman, one of the most respected physicists of the twentieth century, said What I cannot create, I do not understand . Not surprisingly, many physicists and mathematicians have observed fundamental biological processes with the aim of precisely identifying the minimum ingredients that could generate them. One such example are the patterns of nature observed by Alan Turing. The brilliant English mathematician demonstrated in 1952 that it was possible to explain how a completely homogeneous tissue could be used to create

Proposed hierarchical deformation mechanism paradigm for the equi- atomic CrCoNi-based HEAs subjected to increasing degrees of deformation. Elastic deformation, dislocation-mediated plasticity, twinning-induced plasticity, TRIP, and finally solid-state amorphization. Triggering the next mechanism re- quires the generation of additional defects, i.e., dislocations and/or point defects (vacancies). These multiple mechanisms can interact, leading to a synergy of strengthening processes and a resulting highly complex microstructure.

Illustration of a new optical system to miniaturize the laser cooling of atoms, a key step towards cooling atoms on a microchip. A beam of laser light is launched from a photonic integrated circuit (PIC), aided by an element called an extreme mode converter (EMC) that greatly expands the beam. The beam then strikes a carefully engineered, ultrathin film known as a metasurface (MS), which is studded with tiny pillars that further expand and shape the beam. The beam is diffracted from a grating chip to form multiple overlapping laser beams inside a vacuum chamber. The combination of laser beams and a magnetic field efficiently cools and traps a large collection of gaseous atoms in a magneto-optical trap (MOT).
