These theories possess bounded target spaces and vacua that break space-time symmetries. I will give a physical interpretation of these theories as generalized solids with open boundary conditions. I will show that these theories can realize unusual RG flows where higher dimensional (seemingly irrelevant) operators become relevant even at weak coupling. Finally, I will present an example of a field theory whose vacuum energy relaxes to a hierarchically small value compared to the UV cut-off.<\/p>\n\n\n\n<div data-wp-interactive=\"core\/file\" class=\"wp-block-file\"><object data-wp-bind--hidden=\"!state.hasPdfPreview\" hidden class=\"wp-block-file__embed\" data=\"https:\/\/projects.ift.uam-csic.es\/holotube\/wp-content\/uploads\/2024\/01\/Holotube_2023.pdf\" type=\"application\/pdf\" style=\"width:100%;height:600px\" aria-label=\"Embed of Embed of Slides..\"><\/object><a id=\"wp-block-file--media-34475480-4786-49cb-bf97-bb940a3daff6\" href=\"https:\/\/projects.ift.uam-csic.es\/holotube\/wp-content\/uploads\/2024\/01\/Holotube_2023.pdf\">Slides<\/a><a href=\"https:\/\/projects.ift.uam-csic.es\/holotube\/wp-content\/uploads\/2024\/01\/Holotube_2023.pdf\" class=\"wp-block-file__button\" download aria-describedby=\"wp-block-file--media-34475480-4786-49cb-bf97-bb940a3daff6\">Download<\/a><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Date : January 16, 2024, 16:00 CET Alberto Nicolis (Columbia University) Link:&nbsp;https:\/\/ua-edu.zoom.us\/j\/86037901654?pwd=bkVHY1pGYUdqcDF3SnhQb2lHSGVkQT09 Apparent fine-tunings from broken spacetime symmetries Abstract: I will exhibit a class of effective field theories that have hierarchically small Wilson coefficients for operators that are not protected by symmetries but are not finely tuned.
