Ultraviolet phenomena in AdS self-interacting quantum field theory

Emil Akhmedov  MITP & ITEP, Moscow, Russia Abstract: We study the one-loop corrections to the four-point function in the Anti de Sitter space-time for a ϕ4 field theory. Our calculation shows the existence of non-local counterterms which however respect the AdS isometry. Our arguments are quite general and applicable to other (non-conformal) AdS field theories. We also explain…

From Matter to Dark Matter and Dark Energy

From Matter to Dark Matter and Dark Energy Kazem Azizi Doğuş Üniversitesi   Abstract: I will review the recent experimental and theoretical progresses made on the spectroscopy and decay properties of the standard and non-conventional (exotic) hadrons emphasizing on the works by our phenomenology group. I will discuss how our predictions on the existence or…

Exotic Massive 3D Gravity

Exotic Massive 3D Gravity Mehmet Özkan Physics Engineering Department, Istanbul Technical University Abstract: The linearized equations of “New Massive Gravity” propagate a parity doublet of massive spin-2 modes in 3D Minkowski spacetime, but a different non-linear extension is made possible by “third-way” consistency. The new equations can be derived from a “Chern-Simons-like” action, as for…

Gravitational Wave Astronomy

Kai Schwenzer Istanbul University, Department of Astronomy and Space Science   Abstract: The recent observation of the first neutron star merger, both across the electromagnetic spectrum and in gravitational waves, heralds the era of gravitational wave astronomy. Inferring the properties of dense matter is one of the most exciting applications of this emerging area of…

Düzensiz Sistemlerde Topolojik Faz Geçişleri: Taşınım, Evrensel İstatistik ve Weyl Açılımı

Düzensiz Sistemlerde Topolojik Faz Geçişleri: Taşınım, Evrensel İstatistik ve Weyl Açılımı Barış Pekerten Sabancı Üniversitesi, Mühendislik ve Doğa Bilimleri Fakültesi Özet: Kuantum bilgisayarların ve birçok yeni devre elemanının temeli olmaya aday olan topolojik süperiletkenlerin deneyde ayırdedici şekilde gözlemlenmesi, son yılların açık ve önemli sorularından biridir. Topolojik süperiletkenlerin kenar halleri, kendisinin antiparçacığı olan ve nonabelyen heryon(*)…
