Source breakup dynamics in Au+Au Collisions at sqrt(s_NN)=200 GeV via three-dimensional two-pion source imaging
PHENIX Collaboration, S. Afanasiev
A three-dimensional (3D) correlation function obtained from mid-rapidity, low pT pion pairs in central Au+Au collisions at sqrt(s_NN)=200 GeV is studied. The extracted model-indepe…
Conformal transformation in the scalar-tensor theory applied to the accelerating universe
Yasunori Fujii
The scalar-tensor theory is plagued by nagging questions if different conformal frames, in particular the Jordan and Einstein conformal frames, are equivalent to each other. As a c…
Entropy Function and Universality of Entropy-Area Relation for Small Black Holes
Rong-Gen Cai, Chiang-Mei Chen, Kei-ichi Maeda +2
We discuss the entropy-area relation for the small black holes with higher curvature corrections by using the entropy function formalism and field redefinition method. We show that…
Numerical experiments of adjusted BSSN systems for controlling constraint violations
Kenta Kiuchi, Hisa-aki Shinkai
We present our numerical comparisons between the BSSN formulation widely used in numerical relativity today and its adjusted versions using constraints. We performed three testbeds…
Estimation of the Repeatedly-Projected Reduced Density Matrix under Decoherence
H. Nakazato, K. Yuasa, B. Militello +1
Decoherence is believed to deteriorate the ability of a purification scheme that is based on the idea of driving a system to a pure state by repeatedly measuring another system in…
Bulk scalar emission from a rotating black hole pierced by a tense brane
Tsutomu Kobayashi, Masato Nozawa, Yu-ichi Takamizu
We study the emission of scalar fields into the bulk from a six-dimensional rotating black hole pierced by a 3-brane. We determine the angular eigenvalues in the presence of finite…
