Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Ethan T. Ritz, Nicole A. Benedek, , , | Summary: The sensitivity of materials properties, particularly those of perovskite oxides, to epitaxial strain has been exploited to great advantage to create materials with new or enhanced properties. Although it has certainly been recognized that mismatch in […]
Kavli Affiliate: Michael M. Fausnaugh | First 5 Authors: Anna V. Payne, Benjamin J. Shappee, Jason T. Hinkle, Patrick J. Vallely, Christopher S. Kochanek | Summary: We present the discovery that ASASSN-14ko is a periodically flaring AGN at the center of the galaxy ESO 253-G003. At the time of its discovery by the All-Sky Automated […]
Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, , , | Summary: Starting with the de Broglie–Proca Lagrangian for a massive vector field, we calculate the number density of particles resulting from gravitational particle production (GPP) during inflation, with detailed consideration to the evolution of the number density […]
Kavli Affiliate: Katia Bertoldi | First 5 Authors: Gabriele Librandi, Eleonora Tubaldi, Katia Bertoldi, , | Summary: Nonreciprocity can be passively achieved by harnessing material nonlinearities. In particular, networks of nonlinear bistable elements with asymmetric energy landscapes have recently been shown to support unidirectional transition waves. However, in these systems energy can be transferred only […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Hiroki Yoneda, Kazuo Makishima, Teruaki Enoto, Dmitry Khangulyan, Takahiro Matsumoto | Summary: To understand the nature of the brightest gamma-ray binary system LS 5039, hard X-ray data of the object, taken with the Suzaku and NuSTAR observatories in 2007 and 2016, respectively, were analyzed. The two data […]
Kavli Affiliate: Tom Melia | First 5 Authors: Lukas Graf, Brian Henning, Xiaochuan Lu, Tom Melia, Hitoshi Murayama | Summary: We apply Hilbert series techniques to the enumeration of operators in the mesonic QCD chiral Lagrangian. Existing Hilbert series technologies for non-linear realizations are extended to incorporate the external fields. The action of charge conjugation […]
Kavli Affiliate: Leon Balents | First 5 Authors: Kasra Hejazi, Zhu-Xi Luo, Leon Balents, , | Summary: We study untwisted heterobilayers of ferromagnetic and antiferromagnetic van der Waals materials, with in particular a Dzyaloshinskii-Moriya interaction in the ferromagnetic layer. A continuum low energy field theory is utilized to study such systems. We develop a phase […]
Kavli Affiliate: Harry A. Atwater | First 5 Authors: Souvik Biswas, William S. Whitney, Meir Y. Grajower, Kenji Watanabe, Takashi Taniguchi | Summary: Black phosphorus (BP) offers considerable promise for infrared and visible photonics. Efficient tuning of the bandgap and higher subbands in BP by modulation of the Fermi level or application of vertical electric […]
Kavli Affiliate: Lina Necib | First 5 Authors: Laura J. Chang, Lina Necib, , , | Summary: The distribution of dark matter in dwarf galaxies can have important implications on our understanding of galaxy formation as well as the particle physics properties of dark matter. However, accurately characterizing the dark matter content of dwarf galaxies […]
Kavli Affiliate: Shinichiro Takeda | First 5 Authors: Tenyo Kawamura, Tadashi Orita, Shin’ichiro Takeda, Shin Watanabe, Hirokazu Ikeda | Summary: We present our latest ASIC, which is used for the readout of Cadmium Telluride double-sided strip detectors (CdTe DSDs) and high spectroscopic imaging. It is implemented in a 0.35 um CMOS technology (X-Fab XH035), consists […]
