Valley-spin polarized Landau levels in a monolayer semiconductor

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- […]

GHz-Band Integrated Magnetic Inductors

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 […]

Hard superconducting gap in InSb nanowires

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 […]

KELT-18b: Puffy Planet, Hot Host, Probably Perturbed

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 […]

Canonical tilting relative generators

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 […]

Direct and parametric synchronization of a graphene self-oscillator

Kavli Affiliate: P. G. Steeneken | Summary:We explore the dynamics of a graphene nanomechanical oscillator coupled to a reference oscillator. Circular graphene drums are forced into self-oscillation, at a frequency fosc, by means of photothermal feedback induced by illuminating the drum with a continuous-wave red laser beam. Synchronization to a reference signal, at a frequency […]

An automated system to measure the quantum efficiency of CCDs for astronomy

Kavli Affiliate: Homer Neal | Summary:We describe a system to measure the Quantum Efficiency in the wavelength range of 300 nm to 1100 nm of 40×40 mm n-channel CCD sensors for the construction of the 3.2 gigapixel LSST focal plane. The technique uses a series of instrument to create a very uniform flux of photons […]

ALMA Long Baseline Campaigns: Phase Characteristics of Atmosphere at Long Baselines in the Millimeter and Submillimeter Wavelengths

Kavli Affiliate: Richard Hills | Summary:This paper presents the first detailed investigation of the characteristics of mm/submm phase fluctuation and phase correction methods obtained using ALMA with baseline lengths up to ~15 km. Most of the spatial structure functions (SSFs) show that the phase fluctuation increases as a function of baseline length, with a power-law […]

Multigraded linear series and recollement

Kavli Affiliate: Yukari Ito | Summary:Given a scheme $Y$ equipped with a collection of globally generated vector bundles $E_1, dots, E_n$, we study the universal morphism from $Y$ to a fine moduli space $mathcalM(E)$ of cyclic modules over the endomorphism algebra of $E:=mathcalO_Yoplus E_1opluscdots oplus E_n$. This generalises the classical morphism to the linear series […]
