Hi all, Tomorrow our new postdoc Esteban Castro will tell us about his research, specifically "Regular representation approach to quantum reference frame transformations". See below for the abstract. We start at 2pm on zoom: https://ethz.zoom.us/j/362994444 Best, Joe ------ Recent works on quantum reference frames outline a promising research direction to study space and time from an inherently quantum point of view. In this talk, I will summarise some important aspects of these works and present a new method for quantum reference frame transformations, which complements previous approaches. As an application of the method, I will discuss quantum reference frame transformations for the (centrally extended) Galilei group.
