The new techniques allow us to<br class="">determine new saddle points which play important dynamical roles, e.g. in confinement,<br class="">theta-dependence in semi-classically calculable domains. It also<br class="">provides new insights into the nature of IR-renormalon problem. In a<br class="">wide class of quantum mechanical systems, these techniques show that<br class="">all non-perturbative data is secretly encoded in perturbation theory.<br class=""><br class=""><br class="">The link to remotely connect via bluejeans is available at <a href="https://www.jlab.org/div_dept/theory/seminars/2018-spring-theory-seminar.html" class="">https://www.jlab.org/div_dept/theory/seminars/2018-spring-theory-seminar.html</a><br class="">The (partial) schedule for the next seminars is available at the same page.<br class=""><br class="">Looking forward to seeing you,<br class=""><br class=""> Alessandro, Andrea, Bipasha<br class=""><br class="">-- <br class="">Postdoctoral researcher<br class="">Theory Center - Jefferson Lab<br class="">12000 Jefferson Avenue,<br class="">Newport News, VA 23606 USA<br class="">CEBAF center, office A211<br class="">Tel: +1 (757) 269-6735<br class=""><a href="https://userweb.jlab.org/~asignori" class="">https://userweb.jlab.org/~asignori</a><br class=""><br class="">_______________________________________________<br class="">Theory-seminars mailing list<br class="">Theory-seminars@jlab.org<br class="">https://mailman.jlab.org/mailman/listinfo/theory-seminars<br class=""></div></div></blockquote></div><br class=""><div class="">
