Among others, it was studied by H. A. Kramers in the case of the Gaussian white noise in overdamped (large viscosity) and underdamped (small viscosity) regimes. In the overdamped regime, the obtained formula for the reaction rate can be interpreted as the Arrhenius equation. Therefore, the stochastic motion in the double-well potential can be used as an effective model of chemical reactions.</div><div class="" style="margin: 0px; font-stretch: normal; line-height: normal;">Since then, the noise induced escape of a particle was intensively studied in the overdamped and underdamped regimes as well as in quantum setups. I will present extension of problem of the transition rates in a double-well potential to the case of Lévy noises in both over- and underdamped regime.</div></div></div><div class="" style="font-family: HelveticaNeue; margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;"><br class=""></div><div class="" style="font-family: HelveticaNeue; margin: 0px; font-stretch: normal; line-height: normal;">The seminar will be conducted on Zoom</div><div class="" style="font-family: HelveticaNeue; margin: 0px; font-stretch: normal; line-height: normal; color: rgb(220, 161, 13);"><span class="" style="text-decoration: underline;"><a href="https://zoom.us/j/92987083349?pwd=YTZLSFVWUnJzdE4xS1drR3dqMVFDdz09" class="">https://zoom.us/j/92987083349?pwd=YTZLSFVWUnJzdE4xS1drR3dqMVFDdz09</a></span></div><div class="" style="font-family: HelveticaNeue; margin: 0px; font-stretch: normal; line-height: normal;">and will begin at <b class="">9:30AM</b>. </div><div class="" style="font-family: HelveticaNeue; margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;"><br class=""></div><div class="" style="font-family: HelveticaNeue; margin: 0px; font-stretch: normal; line-height: normal; min-height: 14px;"><br class=""></div><div class="" style="font-family: HelveticaNeue; margin: 0px; text-align: justify; font-stretch: normal; line-height: normal;">Maria Ekiel-Jeżewska</div><div class="" style="font-family: HelveticaNeue; margin: 0px; text-align: justify; font-stretch: normal; line-height: normal;">Maciej Lisicki</div><div class="" style="font-family: HelveticaNeue; margin: 0px; text-align: justify; font-stretch: normal; line-height: normal;">Marek Napiórkowski</div><div class="" style="font-family: HelveticaNeue; margin: 0px; text-align: justify; font-stretch: normal; line-height: normal;">Piotr Szymczak</div><div class="" style="font-family: HelveticaNeue; margin: 0px; text-align: justify; font-stretch: normal; line-height: normal;"><br class=""></div><div class="" style="font-family: HelveticaNeue; margin: 0px; text-align: justify; font-stretch: normal; line-height: normal;">Seminar website: <a href="https://www.fuw.edu.pl/seminarium-fizyki-statystycznej.html" class="">https://www.fuw.edu.pl/seminarium-fizyki-statystycznej.html</a></div>
