Kavli Affiliate: Kyle Shen | First 5 Authors: Matthew Molloy, Matthew Molloy, , , | Summary: We describe a method to extract resonant orbits from N-body simulations exploiting the fact that they close in a frame rotating with a constant pattern speed. Our method is applied to the N-body simulation of the Milky Way by […]
Kavli Affiliate: Sander Tans | Summary:The mean size of exponentially dividing E. coli cells cultured in different nutrient conditions is known to depend on the mean growth rate only. However, the joint fluctuations relating cell size, doubling time and individual growth rate are only starting to be characterized. Recent studies in bacteria (i) revealed the […]
Kavli Affiliate: Miriam Blaauboer | Summary:We study the effect of disorder in strongly interacting small atomic chains. Using the Kotliar- Ruckenstein slave-boson approach we diagonalize the Hamiltonian via scattering matrix theory. We numerically solve the Kondo transmission and the slave-boson parameters that allow us to calculate the Kondo temperature. We demonstrate that in the weak […]
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 […]
