Non-vacuum metrics for the Newman-Unti-Tamburino background: A coordinate-free approach to diverging and twisting solutions
Ayşe Hümeyra Bilge, Tolga Birkandan, Tekin Dereli +1
The geometry of the Newman-Unti-Tamburino (NUT) vacuum solution is characterized as the unique Petrov Type D vacuum metric such that the two double principal null directions form a…
Significant reflection and absorption effects in the X-ray emission of the Intermediate Polar IGR J17195-4100
Elif Şafak, Şölen Balman, Gloria Sala
X-ray emission is from shock-heated plasma in magnetic cataclysmic variables, and is processed by absorption and scattering before reaching the observer. We investigate these effec…
Physics for the environment and sustainable development
Jürgen Kurths, Ankit Agarwal, Ugur Öztürk +3
A reliable understanding of the Earth system is essential for the life quality of modern society. Natural hazards are the cause of most life and resource losses. The ability to def…
XY-Ashkin-Teller Phase Diagram in d=3
Alpar Turkoglu, A. Nihat Berker
The phase diagram of the Ashkin-Tellerized XY model in spatial dimension is calculated by renormalization-group theory. In this system, each site has two spins, each spin bei…
Broad Observational Perspectives Achieved by the Accreting White Dwarf Sciences in the XMM-Newton and Chandra Eras
Solen Balman, Marina Orio, Gerardo J. M. Luna
Accreting white dwarf binaries (AWDs) comprise cataclysmic variables (CVs), symbiotics, AM CVns, and other related systems that host a primary white dwarf (WD) accreting from a mai…
Global Ashkin-Teller Phase Diagrams in Two and Three Dimensions: Multicritical Bifurcation versus Double Tricriticality Endpoint
Ibrahim Kecoglu, A. Nihat Berker
The global phase diagrams of the Askin-Teller model are calculated in d=2 and 3 by renormalization-group theory that is exact on the hierarchical lattice and approximate on the rec…
