Nötron Yıldızı Birleşmesinden Boşluk Enerjisi Konusunda Cıvıltılar

Cem Eroncel Syracuse University Özet: İki nötron yıldızının birleşimi oluşu ortaya çıkan kütleçekim dalgalarının LIGO/Virgo tarafından gözlemlenmesi, fiziğin her alanında olduğu gibi, kuramsal yüksek enerji fiziği alanında da yeni bir ufuk açmış oldu. Bu gözlem, nötron yıldızlarının merkezlerinde bulunması muhtemel egzotik Kuantum Renk Dinamiği (KRD) fazlarının incelenebilmesi için bir deney ortamı sunuyor. Bu fazların en…

An Action for Extended String Newton-Cartan Gravity

Ceyda Şimşek University of Groningen, Netherlands Abstract: An action for four-dimensional extended string Newton-Cartan gravity can be obtained as a nonrelativistic limit of the Einstein-Hilbert action in General Relativity augmented with a term that contains an auxiliary two-form and one-form gauge field that both have zero flux on-shell. The construction of four-dimensional extended string Newton-Cartan gravity…

Matching of dynamical systems: With an introduction to Geometric Mechanics

Oğul Esen Gebze Technical University, Gebze Abstract: The talk will be consisting of two main parts. In the first one, a gentle introduction to the geometric mechanics will be presented. Accordingly, some basic notions of the theory namely, Lie groups, Lie algebras, Poisson manifolds and Hamiltonian systems, Euler-Poincaré and Lie-Poisson equations, will be exhibited. Several…

ImF-method and real-time approach to the dynamics of superconducting bridges and Josephson junctions at low temperature

Andrew Semenov Lebedev Physical Institute, Moscow, Russia Abstract: One of the standard approach for estimation of tunneling rates in quantum systems is so-called ImF-method. It is based on the evaluation of the imaginary part of free energy which originates after some analytic continuation procedure. However, in the experiments, one can’t measure macroscopic tunneling rates directly…

Hidden Symmetries Near the Black Hole Horizon

Saeedeh Sadeghian IPM, Tehran, Iran   Abstract: We study the hidden symmetries, the symmetries associated with Killing tensors, of the near-horizon geometry of odd-dimensional Kerr-AdS-NUT black holes in two limits: generic extremal and extremal vanishing horizon (EVH) limits. Starting from a Kerr-AdS-NUT black hole in ellipsoidal coordinates which admit integrable geodesic equations, we obtain the…

Searching for CP Violation in DUNE and Sterile Neutrinos in MicroBooNE

Fatih Bay TUBITAK, Ankara, Turkey Özet: Neutrino Oscillations have been firmly established by experiments conducted in the last two decades with solar, atmospheric, accelerator and reactor neutrinos leading to the determination of the neutrino mass-eigenvalue differences (squared) and of the three angles of the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) mixing matrix. Outstanding issues are still to be settled…

Inverse scattering problem for nonstationary Dirac-type system and some of its applications

Mansur I. Ismailov Department of Mathematics, Gebze Technical University Abstract: The inverse scattering problem (ISP) for a first-order nonstrict hyperbolic system (in the literature, this system is also called the nonstationary Dirac-type system) on the whole plane is considered. It is well known that every linear equation, which the ISP is effectively solved for, determines…
