Gravitational Waves from Holographic Neutron Star Mergers
Christian Ecker, Matti Järvinen, Govert Nijs +1
We simulate the merger of binary neutron stars and analyze the spectral properties of their gravitational waveforms. For the stars we construct hybrid equations of state (EoSs) wit…
Quantum Null Energy Condition and its (non)saturation in 2d CFTs
Christian Ecker, Daniel Grumiller, Wilke van der Schee +2
We consider the Quantum Null Energy Condition (QNEC) for holographic conformal field theories in two spacetime dimensions (CFT). We show that QNEC saturates for all states dual…
Stiff phases in strongly coupled gauge theories with holographic duals
Christian Ecker, Carlos Hoyos, Niko Jokela +2
According to common lore, Equations of State of field theories with gravity duals tend to be soft, with speeds of sound either below or around the conformal value of $v_s=1/\sqrt{3…
Density response and collective modes of semi-holographic non-Fermi liquids
Benoit Doucot, Christian Ecker, Ayan Mukhopadhyay +1
Semi-holographic models of non-Fermi liquids have been shown to have generically stable generalised quasi-particles on the Fermi surface. Although these excitations are broad and e…
