Deconstructing Schrödinger's cat

The paradox of Schrödinger's cat—the feline that is, famously, both alive and dead until its box is opened—is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seem to predict that ...

How nature tells us its formulas

Many of the biggest questions in physics can be answered with the help of quantum field theories: They are needed to describe the dynamics of many interacting particles, and thus they are just as important in solid state ...

Designing lasers based on quantum physics

A five-country research team coordinated by Germán J. de Valcárcel Gonzalvo, Professor of Optics at the University of Valencia, has developed a new theory —the coherent master equation— that describes the behavior of ...
