Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Matthew Dodelson, Hirosi Ooguri, , , | Summary: We analyze the singularities of the two-point function in a conformal field theory at finite temperature. In a free theory, the only singularity is along the boundary light cone. In the holographic limit, a new class of singularities emerges […]
Kavli Affiliate: Masahiro Kawasaki | First 5 Authors: Masahiro Kawasaki, Wakutaka Nakano, Hiromasa Nakatsuka, Eisuke Sonomoto, | Summary: In string theory, the simultaneous existence of many Axion-Like Particles (ALPs) are suggested over a vast mass range, and a variety of potentials have been developed in the context of inflation. In such potentials shallower than quadratic, […]
Kavli Affiliate: Kerry Vahala | First 5 Authors: Heming Wang, Lue Wu, Zhiquan Yuan, Kerry Vahala, | Summary: Narrow-linewidth lasers are important to many applications spanning precision metrology to sensing systems. Their miniaturization in the form of on-chip lasers is receiving increasing attention. Here, a noise level that is consistent with a fundamental frequency noise […]
