Wormhole effects in quantum black hole physics

<!--HTML--><p><span style="color:rgb(0,0,0);"><span style="-webkit-text-size-adjust:auto;-webkit-text-stroke-width:0px;caret-color:rgb(0, 0, 0);display:inline !important;float:none;font-family:Helvetica;font-size:12px;font-style:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;orphans:auto;text-align:start;text-decoration:none;text-indent:0px;text-transform:none;white-space:normal;widows:auto;word-spacing:0px;">A powerful idea in theoretical physics is the conjecture that (from a distance) black holes behave like ordinary quantum systems. Thought of in this way, black holes display many deep quantum phenomena in&nbsp;simple but often surprising ways. We will discuss recent work (involving wormholes) that gives new examples of this and also uncovers new puzzles.</span></span></p>
