We show that this complete gradient estimate is stable under tensor products and free products and establish its validity for a number of examples. As an application we prove a complete modified logarithmic Sobolev inequality with optimal constant for Poisson-type semigroups on free group factors.","lang":"eng"}],"date_published":"2021-08-30T00:00:00Z","department":[{"_id":"JaMa"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","doi":"10.1007/s00220-021-04199-4","status":"public","article_type":"original","volume":387,"_id":"9973","external_id":{"isi":["000691214200001"],"arxiv":["2007.13506"]},"publication":"Communications in Mathematical Physics","type":"journal_article","day":"30","isi":1,"scopus_import":"1","publication_status":"published","month":"08","language":[{"iso":"eng"}],"acknowledgement":"Both authors would like to thank Jan Maas for fruitful discussions and helpful comments.","quality_controlled":"1","publisher":"Springer Nature","page":"761–791","date_created":"2021-08-30T10:07:44Z","has_accepted_license":"1","file":[{"creator":"cchlebak","file_name":"2021_CommunMathPhys_Wirth.pdf","relation":"main_file","checksum":"8a602f916b1c2b0dc1159708b7cb204b","access_level":"open_access","date_created":"2021-09-08T07:34:24Z","date_updated":"2021-09-08T09:46:34Z","file_size":505971,"file_id":"9990","content_type":"application/pdf"}],"ddc":["621"],"title":"Complete gradient estimates of quantum Markov semigroups","year":"2021","ec_funded":1,"keyword":["Mathematical Physics","Statistical and Nonlinear Physics"],"project":[{"_id":"B67AFEDC-15C9-11EA-A837-991A96BB2854","name":"IST Austria Open Access Fund"},{"call_identifier":"H2020","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"},{"_id":"fc31cba2-9c52-11eb-aca3-ff467d239cd2","name":"Taming Complexity in Partial Differential Systems","grant_number":"F6504"}],"file_date_updated":"2021-09-08T09:46:34Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"citation":{"ieee":"M.
