Kavli Affiliate: Fukun Liu| Summary: The gyrotron is the high power millimeter wave source in the electron cyclotron resonance heating system for the tokamak. The cathode power supply is one of the most important ancillary devices for gyrotron. Some interesting transient phenomena about the cathode voltage and the cathode current was found in the gyrotron […]
Kavli Affiliate: Hiroaki Aihara | Summary:The Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) is a three-layered imaging survey aimed at addressing some of the most outstanding questions in astronomy today, including the nature of dark matter and dark energy. The survey has been awarded 300 nights of observing time at the Subaru Telescope and it started […]
Kavli Affiliate: Daniel Ralph | First 5 Authors: Ralph Henstock, Ralph Henstock, , , | Summary: Ralph Henstock (1923 – 2007) worked in non-absolute integration, including the Riemann-complete or gauge integral which, independently, Jaroslav Kurzweil also discovered in the 1950’s. As a Cambridge undergraduate Henstock took a course of lectures, by J.C. Burkill, on the […]
Kavli Affiliate: Kiyoshi Wesley Masui | Summary:We show that three-dimensional information is critical to discerning the effects of parity violation in the primordial gravity-wave background. If present, helical gravity waves induce parity-violating correlations in the cosmic microwave background (CMB) between parity-odd polarization $B$-modes and parity-even temperature anisotropies ($T$) or polarization $E$-modes. Unfortunately, $EB$ correlations are […]
Kavli Affiliate: Jie Shan | First 5 Authors: Zefang Wang, Zefang Wang, , , | Summary: Electrons in monolayer transition metal dichalcogenides (TMDs) possess both the valley and spin degree of freedom. These internal quantum degrees of freedom have provided an ideal laboratory for exploring both new physical phenomena and electronics and photonics applications. Valley- […]

Kavli Affiliate: Amal El-Ghazaly | Summary:The demand on mobile electronics to continue to shrink in size while increase in efficiency drives the demand on the internal passive components to do the same. Power amplifiers require inductors with small form factors, high quality factors, and high operating frequency in the single-digit GHz range. This work explores […]
Kavli Affiliate: Sonia Conesa-Boj | Summary:Topological superconductivity is a state of matter that can host Majorana modes, the building blocks of a topological quantum computer. Many experimental platforms predicted to show such a topological state rely on proximity-induced superconductivity. However, accessing the topological properties requires an induced hard superconducting gap, which is challenging to achieve […]
Kavli Affiliate: David A. Tirrell| First 5 Authors: Kim K. McLeod, Kim K. McLeod, , , | Summary:We report the discovery of KELT-18b, a transiting hot Jupiter in a 2.87d orbit around the bright (V=10.1), hot, F4V star BD+60 1538 (TYC 3865-1173-1). We present follow-up photometry, spectroscopy, and adaptive optics imaging that allow a detailed […]
Kavli Affiliate: Alexey Bondal | Summary:Given a relatively projective birational morphism $fcolon Xto Y$ of smooth algebraic spaces with dimension of fibers bounded by 1, we construct tilting relative (over $Y$) generators $T_X,f$ and $S_X,f$ in $mathcalD^b(X)$. We develop a piece of general theory of strict admissible lattice filtrations in triangulated categories and show that […]
