Parameter counting for singular monopoles

Parameter counting for singular monopoles Dieter Van den Bleeken Boğaziçi Üniversitesi Abstract : I will motivate the study of non-Abelian monopoles with singular boundary conditions and the study of their semi classical physics. I will then discuss how one particularly important property, the dimension of their moduli space, can be computed. Yer : MSGSÜ Bomonti Binası,…

On the cosmological constant problem and its relation to the extrinsic shape of the universe

On the cosmological constant problem and its relation to the extrinsic shape of the universe Shahram Jalalzadeh Shahid Beheshti University Abstract : Within the conventional big-bang cosmological model, it is very difficult to understand why the cosmological constant is so small. In this talk, first, I will discuss a new classical unified field theory (like Kaluza-Klein…

4 Boyutta Kütleli S-Düalite

4 Boyutta Kütleli S-Düalite E.Ulaş Saka İstanbul Üniversitesi Fizik Bölümü Sicim teoriler arasındaki düalite ilişkileri, genel olarak teorilerin zayıf ve güçlü etkileşim bölgeleri arasında  bir gönderim olarak tanımlanır.  Teorilerin farklı kompakt  çokkatlılar üzerine indirgenerek düalite ilişkileri  ve teorilerin barındırdıkları simetriler   zenginleştirilebilmektedir. Ayrıca indirgeme mekanizması akı (kompakt koordinatlara özel bir halde bağlı olarak)   terimi eklenerek yapıldığında…

The Non-conformal Hydrodynamics in the Einstein-dilaton Theory

The Non-conformal Hydrodynamics in the Einstein-dilaton Theory Chanyong Park Center for Quantum Spacetime (CQUeST) Sogang University, Seoul Özet/Abstract : We study a general D-dimensional Schwarzschild-type black brane solution of the Einstein-dilaton theory, whose dual theory, following the generalized gauge/gravity duality,is described by a relativistic non-conformal theory. We study the thermodynamics and the hydrodynamics of such…

Hadron structure in lattice QCD

Hadron structure in lattice QCD Güray Erkol Özyeğin Üniversitesi. İstanbul Özet : Lattice QCD is a numerical method, which formulates QCD on a space-time lattice allowing us to obtain information about hadron properties from first principles. It has proved to be rather successful in predicting the spectral properties of mesons and baryons, as well as…

Gamma-ray spectroscopy at GANIL today and tomorrow

Gamma-ray spectroscopy at GANIL today and tomorrow Gilles de France Le Grand Accélérateur National d’Ions Lourds (GANIL) Özet/Abstract : Gamma-ray spectroscopy is intensively used at GANIL to measure low lying states in exotic nuclei on the neutron-rich as well as on the neutron-deficient side of the nuclear chart. To perform this physics program, the EXOGAM…
