Such systems can be used to create synthetic materials with properties that cannot be attained in materials having only loss or only gain. We report PT-symmetry breaking in coupled optical resonators. We observed non-reciprocity in the PT-symmetry-breaking phase due to strong field localization, which significantly enhances nonlinearity. In the linear regime, light transmission is reciprocal regardless of whether the symmetry is broken or unbroken. We show that in one direction there is a complete absence of resonance peaks whereas in the other direction the transmission is resonantly enhanced, which is associated with the use of resonant structures. Our results could lead to a new generation of synthetic optical systems enabling onchip manipulation and control of light propagation. </div> <div> </div> <div>2.<span style="white-space:pre"> </span>The quantum spin Hall effect of light: photonic analog of 3D topological insulators. </div> <div>Maxwell’s equations, formulated 150 years ago, ultimately describe properties of light, from classical electromagnetism to quantum and relativistic aspects. The latter ones result in remarkable geometric and topological phenomena related to the spin-1 massless nature of photons. By analyzing fundamental spin properties of Maxwell waves, we show [2] that free-space light exhibits an intrinsic quantum spin Hall effect —surface modes with strong spin-momentum locking. These modes are evanescent waves that form, for example, surface plasmon-polaritons at vacuum-metal interfaces. Our findings illuminate the unusual transverse spin in evanescent waves and explain recent experiments that have demonstrated the transverse spin-direction locking in the excitation of surface optical modes. This deepens our understanding of Maxwell’s theory, reveals analogies with topological insulators for electrons, and offers applications for robust spindirectional optical interfaces.  Related work can be found in [3]. </div></div> <div><br /></div> <div><a href="/en/departments/mc2/calendar/Documents/franco_nori.pdf"><img class="ms-asset-icon ms-rtePosition-4" src="/en/departments/mc2/calendar/_layouts/images/icpdf.png" alt="" />Abstract and references (pdf</a>)</div> <div><br /></div> ​https://www.chalmers.se/en/departments/mc2/calendar/Pages/LCS-MGL.aspxhttps://www.chalmers.se/en/departments/mc2/calendar/Pages/LCS-MGL.aspxPOSTPONED: Linnaeus Coffee Seminar with ​Martí Gutierrez Latorre<p>Kollektorn, lecture room, Kemivägen 9, MC2-huset</p><p>​​Postpo​ned due to the corona virus situation.​</p>​Title and abstract TBA<div>​<div><span style="background-color:initial">Coffee and cake will be served before the talk at 14.00</span><div>Welcome!</div></div></div>https://www.chalmers.se/en/departments/mc2/calendar/Pages/Josef-Hansson,-MC2.aspxhttps://www.chalmers.se/en/departments/mc2/calendar/Pages/Josef-Hansson,-MC2.aspxJosef Hansson, Microtechnology and Nanoscience -

Historically, Niels Bohr was the first to hypothesize that quantum jumps occurred between two discrete energy levels of an atom. Experimentally, quantum jumps were only directly observed many decades later, in an atomic ion driven by a weak deterministic force under strong continuous energy measurement. The times at which the discontinuous jump transitions occur are reputed to be fundamentally unpredictable. Despite the non-deterministic character of quantum physics, is it possible to know if a quantum jump is about to occur? </div> <div>Our work<span style="font-size:10.5px;line-height:0;vertical-align:baseline;top:-0.5em">1</span> provides a positive answer to this question: we experimentally show that the jump from the ground state to an excited state of a superconducting artificial three-level atom can be tracked as it follows a predictable “flight” by monitoring the population of an auxiliary energy level coupled to the ground state. The experimental results demonstrate that the evolution of the jump — once completed — is continuous, coherent, and deterministic. Based on these insights and aided by real-time monitoring and feedback, we then pinpoint and reverse one such quantum jump “mid-flight”, thus deterministically preventing its completion. Our findings, which agree with theoretical predictions essentially without adjustable parameters, lend support to the modern formulation of quantum trajectory theory; most importantly, they may provide new ground for the exploration of real-time intervention techniques in the control of quantum systems, such as the early detection of error syndromes.</div> <div><br /></div> <div>1.<span style="white-space:pre"> </span>Z.

Already, ultrastrong and deep strong coupling regimes have been experimentally achieved in a variety of platforms (intersubband polaritons, THz-resonators, superconducting circuits, optomechanics, plasmonic cavities, etc.). Nowadays, the focus of the community is shifting to observing the rich and exotic phenomena predicted before, which are promising for future quantum technologies. Such as; breakdown of the Purcell effect, optical higher order processes, polariton and QED chemistry, among others.​</p>​<span style="background-color:initial">This workshop aims at gathering researchers from the USC community, working in interdisciplinary </span><span style="background-color:initial">related fields, to shed light upon where the field is now and where it is heading.
