Kavli Affiliate: Kinfai Mak | First 5 Authors: Kit-Ho Mak, Kit-Ho Mak, , , | Summary: Let $p$ be a prime number, $C$ be any absolutely irreducible affine plane curve over $mathbbF_p$, and $g,finmathbbF_p(x,y)$ be rational functions. We continue the study of the distribution of the values of short hybrid exponential sums of the form […]
Kavli Affiliate: David A. Tirrell | Summary:Biological cells sense and respond to mechanical forces, but how such a mechanosensing proccess takes place in a nonlinear inhomogeneous fibrous matrix remains unknown. We show that cells in a fibrous matrix induce deformation fields that propagate over a longer range than predicted by linear elasticity. Synthetic, linear elastic […]
Kavli Affiliate: Yu V. Nazarov | Summary:The superconducting proximity effect leads to strong modifications of the local density of states in diffusive or chaotic cavity Josephson junctions, which displays a phase-dependent energy gap around the Fermi energy. The so-called minigap of the order of the Thouless energy $E_mathrmTh$ is related to the inverse dwell time […]
Kavli Affiliate: Paul W. Sternberg | Summary:C. elegans is the only animal for which a detailed neural connectivity diagram has been constructed. However, synaptic polarities in this diagram, and thus, circuit functions are largely unknown. Here, we deciphered the likely polarities of 7 pre-motor neurons implicated in the control of worm’s locomotion, using a combination […]
Kavli Affiliate: Ali Javey | Summary:Semiconductor heterostructures are the fundamental platform for many important device applications such as lasers, light-emitting diodes, solar cells and high-electron-mobility transistors. Analogous to traditional heterostructures, layered transition metal dichalcogenide (TMDC) heterostructures can be designed and built by assembling individual single-layers into functional multilayer structures, but in principle with atomically sharp […]
Kavli Affiliate: Ali Javey | Summary:The development of low-resistance source/drain contacts to transition metal dichalcogenides (TMDCs) is crucial for the realization of high-performance logic components. In particular, efficient hole contacts are required for the fabrication of p-type transistors with MoS2, a model TMDC. Previous studies have shown that the Fermi level of elemental metals is […]
Kavli Affiliate: Jie Shan | First 5 Authors: Donato Bini, Donato Bini, , , | Summary: A scalar field equivalent to a non-ideal "dark energy fluid" obeying a Shan-Chen-like equation of state is used as the background source of a flat Friedmann-Robertson-Walker cosmological spacetime to describe the inflationary epoch of our universe. Within the slow-roll […]
Kavli Affiliate: Roel H. M. Smit | Summary:Pt is known to show spontaneous formation of monatomic chains upon breaking a metallic contact. From model calculations, these chains are expected to be spin polarized. However, direct experimental evidence for or against magnetism is lacking. Here, we investigate shot noise as a potential source of information on […]
Kavli Affiliate: Zhiting Tian | First 5 Authors: Zhiting Tian, Zhiting Tian, , , | Summary: Solid-state thermoelectric devices are currently used in applications ranging from thermocouple sensors to power generators in satellites, to portable air-conditioners and refrigerators. With the ever-rising demand throughout the world for energy consumption and CO2 reduction, thermoelectric energy conversion has […]
Kavli Affiliate: Kinfai Mak | First 5 Authors: Kit-Ho Mak, Kit-Ho Mak, , , | Summary: Let $p$ be a prime number, $X$ be an absolutely irreducible affine plane curve over $mathbbF_p$, and $g,finmathbbF_p(x,y)$. We study the distribution of the values of the hybrid exponential sums S_n on $ninmathcalI$ for some short interval $mathcalI$. We […]
