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 […]
Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Ryuichiro Kitano, Norikazu Yamada, Masahito Yamazaki, , | Summary: We study $theta$ dependence of the vacuum energy for the 4d SU(2) pure Yang-Mills theory by lattice numerical simulations. The response of topological excitations to the smearing procedure is investigated in detail, in order to extract topological information […]
Kavli Affiliate: Tom Melia | First 5 Authors: Tom Melia, Sridip Pal, , , | Summary: We establish formulae for the asymptotic growth (with respect to the scaling dimension) of the number of operators in effective field theory, or equivalently the number of $S$-matrix elements, in arbitrary spacetime dimensions and with generic field content. This […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Maulik Parikh, Frank Wilczek, George Zahariade, , | Summary: We develop a formalism to calculate the response of a model gravitational wave detector to a quantized gravitational field. Coupling a detector to a quantum field induces stochastic fluctuations ("noise") in the length of the detector arm. The […]
Kavli Affiliate: Frank Wilczek | First 5 Authors: Maulik Parikh, Frank Wilczek, George Zahariade, , | Summary: For the purpose of analyzing observed phenomena, it has been convenient, and thus far sufficient, to regard gravity as subject to the deterministic principles of classical physics, with the gravitational field obeying Newton’s law or Einstein’s equations. Here […]
Kavli Affiliate: Moritz Guenther | First 5 Authors: Nancy Remage Evans, H. Moritz Guenther, Howard E. Bond, Gail H. Schaefer, Brian D. Mason | Summary: Cepheids in multiple systems provide information on the outcome of the formation of massive stars. They can also lead to exotic end-stage objects. This study concludes our survey of 70 […]
Kavli Affiliate: Simeon Hellerman | First 5 Authors: Simeon Hellerman, Ian Swanson, , , | Summary: We consider the large-charge expansion of the charged ground state of a Schrodinger-invariant, nonrelativistic conformal field theory in a harmonic trap, in general dimension d. In the existing literature, the energy in the trap has been computed to next-to-leading […]
Kavli Affiliate: Shenghan Jiang | First 5 Authors: Brenden Roberts, Shenghan Jiang, Olexei I. Motrunich, , | Summary: We continue recent efforts to discover examples of deconfined quantum criticality in one-dimensional models. In this work we investigate the transition between a $mathbb{Z}_3$ ferromagnet and a phase with valence bond solid (VBS) order in a spin […]
