Novel Observable Signals from First-Order Gravitational Phase Transitions
Murat Ãzinan, Murat Özinan, OÄuzhan K. Yamak +3
Spontaneous scalarization is a well-known phenomenon in scalar-tensor theories, featuring large deviations from general relativity. However, some of its signatures are hard to dete…
Potentially healthy time evolution in interacting -form fields
Fethi M. RamazanoÄlu, Kıvanç Ä°. Ãnlütürk
It was recently discovered that many self-interacting vector fields can have healthy time evolution when field amplitudes are small, however, further dynamics becomes impossible if…
Underlying mechanisms of phase transitions in scalar-tensor theories
Murat Ãzinan, Kıvanç Ä°. Ãnlütürk, Fethi M. RamazanoÄlu
Spontaneous scalarization phenomenon in scalar-tensor gravity is known to be a form of phase transition, and it was recently shown that the order of this transition changes dependi…
Nature of phase transitions and metastability in scalar-tensor theories
Kıvanç Ä°. Ãnlütürk, Semih Tuna, OÄuzhan K. Yamak +1
Compact stars above a critical stellar mass develop large scalar fields in some scalar-tensor theories. This scenario, called spontaneous scalarization, has been an intense topic o…
