Operational Magic Intensity for Sr Optical Lattice Clocks
Ichiro Ushijima, Masao Takamoto, Hidetoshi Katori
We experimentally investigate the lattice-induced light shift by the electric-quadrupole () and magnetic-dipole () polarizabilities and the hyperpolarizability in Sr optica…
How to detect the shortest-period binary pulsars in the era of LISA
Koutarou Kyutoku, Yuki Nishino, Naoki Seto
We discuss a multimessenger strategy to detect radio pulses from Galactic binary neutron stars in a very tight orbit with the period shorter than 10 min. On one hand, all-sky surve…
Organic molecular tuning of many-body interaction energies in air-suspended carbon nanotubes
S. Tanaka, K. Otsuka, K. Kimura +4
We investigate adsorption effects of copper phthalocyanine molecules on excitons and trions in air-suspended carbon nanotubes. Using photoluminescence excitation spectroscopy, we o…
Comparing treatments of weak reactions with nuclei in simulations of core-collapse supernovae
Hiroki Nagakura, Shun Furusawa, Hajime Togashi +3
We perform an extensive study of the influence of nuclear weak interactions on core-collapse supernovae (CCSNe), paying particular attention to consistency between nuclear abundanc…
Tunable Angle Dependent Magnetization Dynamics in Ni80Fe20 Nano-cross Structures of Varying Size
Kartik Adhikari, Saswati Barman, Ruma Mandal +2
We demonstrate a large angular dependence of magnetization dynamics in Ni80Fe20 nano-cross arrays of varying sizes. By subtle variation of the azimuthal angle of an in-plane bias m…
Transverse spin and surface waves in acoustic metamaterials
Konstantin Y. Bliokh, Franco Nori
We consider spin angular momentum density in inhomogeneous acoustic fields: evanescent waves and surface waves at interfaces with negative-density metamaterials. Despite being pure…
