Europe/Rome 2017-07-27 11:30:00 2017-07-27 12:30:00 Condensed Matter Seminar: Superconductivity vs Bond State Formation in a Two Band Superconductor We discuss the interplay between superconductivity and formation of bound pairs of fermions (BCS-BEC crossover) in a 2D model of interacting fermions with small Fermi energy ϵF and a weak attractive interaction, which extends to energies well above ϵ_F. The 2D case is special because a two-particle bound state forms at arbitrary weak interaction, and already at weak coupling, one has to distinguish between the bound-state formation and superconductivity. We briefly review the situation in the one-band model and then consider two different two-band models: one with one hole band and one electron band and another with two hole or two electron bands. At ϵ_F≫E_0, where E_0 is the energy of the bound state of two particle in vacuum, the two models behave similar. But in the opposite case they behave differently: in the model with two hole/two electron bands, the instability temperature of formation of cooper pairs T_ins∼E_0/(logE_0/ϵ_F ), and the true superconducting critical temperature T_c∼ϵ_F, like in the one-band model. In between T_ins and T_c, the system displays a preformed pair behavior. In the model with one hole and one electron bands, T_c remains of order T_ins, and both remain finite at ϵ_F=0 and of the order of E_0. The preformed pair behavior still does exist in this model because T_c is numerically smaller than T_ins. ICTP ICTP pio@ictp.it 27 Jul 2017

At the same time it has been the key to the design of new nano-devices with specific functionalities. Together with old problems, still awaiting for a complete understanding, the discovery of new materials has posed new challenges. Important advances on the experimental side have stimulated a flurry of theoretical activity of unprecedented intensity. In the condensed matter realm this is the case, for example, of heat transport and control that only recently has received an important experimental boost. Furthermore, quantum transport has moved outside its traditional arena and it is now investigated with great success in other experimental platforms as photonic and cold atomic systems. All these different physical systems have many properties in common but at the same time important differences. Topics that will be covered include: The Superconductor-Insulator Transition, Transport In Graphene, The Metal-Insulator Transition In Quantum Systems, Transport And Entanglement, Topological Insulators And Superconductors, Mesoscopic Effects, Thermoelectric Effects, Heat Transport, Quantum Pumping, Photon And Polariton Transport, Quantum Transport In Cold Atoms, Quantum Hall Systems.

Europe/Rome 2017-09-18 08:00:00 2017-09-22 22:00:00 Advanced School on Foundations and Applications of Nanomechanics | (smr 3147) ATTENTION new deadline 15 June 2017 This school introduces the science of nanomechanical systems, a flourishing field of research. Nanomechanical systems are of interest both for their potential in terms of fundamental quantum physics as well as for applications in sensitive measurements, quantum information, and other areas. This Advanced School will recapitulate the foundations of nanomechanical systems and introduce the key concepts behind nano- and optomechanical technologies. The breadth of the field will be covered in six series of lectures delivered by internationally renowned experts. The pedagogical part of the school will be complemented by a series of about 20 invited presentations of state-of-the-art research. A crucial part of the school, in addition to the lectures and talks, will be the active contribution of the participants, which will be encouraged and fostered by several means: During the first week of the school, designated timeslots for tutorial classes will enable students to practice their skills in analytical as well as numerical methods, and will include problem solving and presentation of scientific results. The participants will work in small teams on research-type mini-projects. Lecturers: Yaroslav M.
