For these dynamics, Holley and Stroock made the key observation that systems thermalizing in times scaling logarithmically in the system size, a property known as rapid mixing, satisfy exponential decay of correlations at equilibrium. The converse implication, namely that exponential decay of correlations implies rapid mixing, was investigated later on in a series of articles by Zegarlinski and Stroock, who proved the stronger condition of an exponential entropic decay of the dynamics towards the limiting Gibbs measure, also known as logarithmic Sobolev inequality. In this talk, we will prove an extension of the result of Zegarlinski and Stroock to the quantum setting. More precisely, we will show that, given the Gibbs state $\sigma$ of a 2-local commuting Hamiltonian and above a critical temperature, there exists a local quantum Markovian evolution converging to $\sigma$ which satisfies the quantum modified logarithmic Sobolev inequality (MLSI) with a constant that does not depend on the size of the lattice. As a first step towards this proof, we will also provide a proof of the existence of the MLSI for finite dimensional systems coupled to an arbitrarily large, noiseless environment (also known as the complete MLSI constant), a problem that was left open until now.</p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>This talk is based on the following papers:</p></div><div><p class=MsoNormal><a href="https://arxiv.org/abs/2009.11817" target="_blank">https://arxiv.org/abs/2009.11817</a></p></div><div><p class=MsoNormal><a href="https://arxiv.org/abs/2102.04146" target="_blank">https://arxiv.org/abs/2102.04146</a></p></div></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>--------</p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><div><p class=MsoNormal>Dottorato Matematica is inviting you to a scheduled Zoom meeting.</p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Topic: Seminars April 19 to 22</p></div><div><p class=MsoNormal>Time: Apr 19, 2021 05:00 PM Rome</p></div><div><p class=MsoNormal> Apr 20, 2021 05:00 PM</p></div><div><p class=MsoNormal> Apr 22, 2021 04:00 PM</p></div><div><p class=MsoNormal>Please download and import the following iCalendar (.ics) files to your calendar system.</p></div><div><p class=MsoNormal>Weekly: <a href="https://us02web.zoom.us/meeting/tZ0oc-qpqzwrG9W8L60lAyfp8kbqksDUWlwv/ics?icsToken=98tyKuGhqz8pG9GSsRiGRpx5GY-gb-vwmGZcjfpqxDOzUyxyewXmbulAI7lsNO3n" target="_blank">https://us02web.zoom.us/meeting/tZ0oc-qpqzwrG9W8L60lAyfp8kbqksDUWlwv/ics?icsToken=98tyKuGhqz8pG9GSsRiGRpx5GY-gb-vwmGZcjfpqxDOzUyxyewXmbulAI7lsNO3n</a></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Join Zoom Meeting</p></div><div><p class=MsoNormal><a href="https://us02web.zoom.us/j/89543157111?pwd=NnAyblhVNkppeERRRFd1VGYwTkMyUT09" target="_blank">https://us02web.zoom.us/j/89543157111?pwd=NnAyblhVNkppeERRRFd1VGYwTkMyUT09</a></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Meeting ID: 895 4315 7111</p></div><div><p class=MsoNormal>Passcode: 029655</p></div><div><p class=MsoNormal>One tap mobile</p></div><div><p class=MsoNormal>+13017158592,,89543157111# US (Washington DC)</p></div><div><p class=MsoNormal>+13126266799,,89543157111# US (Chicago)</p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Dial by your location</p></div><div><p class=MsoNormal> +1 301 715 8592 US (Washington DC)</p></div><div><p class=MsoNormal> +1 312 626 6799 US (Chicago)</p></div><div><p class=MsoNormal> +1 646 876 9923 US (New York)</p></div><div><p class=MsoNormal> +1 346 248 7799 US (Houston)</p></div><div><p class=MsoNormal> +1 408 638 0968 US (San Jose)</p></div><div><p class=MsoNormal> +1 669 900 6833 US (San Jose)</p></div><div><p class=MsoNormal> +1 253 215 8782 US (Tacoma)</p></div><div><p class=MsoNormal>Meeting ID: 895 4315 7111</p></div></div></div></div><p class=MsoNormal>Find your local number: <a href="https://us02web.zoom.us/u/kd3YVb722z" target="_blank">https://us02web.zoom.us/u/kd3YVb722z</a></p></div></body></html>
