Anharmonicity strongly enhancing thermal interface conductance: A new anharmonic atomistic Green’s function formalism

Posted by klaurent Cornell

Kavli Affiliate: Zhiting Tian | First 5 Authors: Jinghang Dai, Jinghang Dai, , , | Summary: The traditional atomistic Green’s function (AGF) was formulated in the harmonic regime, preventing it from capturing the role of anharmonicity in interfacial thermal transport. Incorporating anharmonicity into AGF has long been desired but remains challenging. We developed a rigorous […]

Heliosheath Properties Measured from a Voyager 2 to Voyager 1 Transient

Posted by klaurent MIT

Kavli Affiliate: John Richardson | Summary:In mid-2012, a GMIR observed by Voyager 2 crossed through the heliosheath and collided with the heliopause, generating a pressure pulse that propagated into the very local interstellar medium. The effects of the transmitted wave were seen by Voyager 1 just 93 days after its own heliopause crossing. The passage […]

High-Throughput Detection and Manipulation of Single Nitrogen-Vacancy Center’s Charge in Nanodiamonds

Posted by klaurent Oxford

Kavli Affiliate: Achillefs Kapanidis | Summary:The fluorescent nitrogen-vacancy (NV) defect in diamond has remarkable photophysical properties, including high photostability, which allows stable fluorescence emission for hours; as a result, there has been much interest in using nanodiamonds (NDs) for quantum optics and biological imaging. Such applications have been limited by the complexity and heterogeneity of […]

Electric-Double-Layer-Modulation Microscopy

Posted by klaurent Oxford

Kavli Affiliate: Philipp Kukura | Summary:The electric double layer (EDL) formed around charged nanostructures at the liquid-solid interface determines their electrochemical activity and influences their electrical and optical polarizability. We experimentally demonstrate that restructuring of the EDL at the nanoscale can be detected by dark-field scattering microscopy. Temporal and spatial characterization of the scattering signal […]

Ramanujan’s influence on string theory, black holes and moonshine

Posted by Chicago

Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: Jeffrey A. Harvey, , , , | Summary: Ramanujan influenced many areas of mathematics, but his work on q-series, on the growth of coefficients of modular forms, and on mock modular forms stands out for its depth and breadth of applications. I will give a brief […]

On Deflection of Solar Coronal Mass Ejections by the Ambient Coronal Magnetic Field Configuration

Posted by klaurent Stanford

Kavli Affiliate: J. Todd Hoeksema | Summary:Solar Coronal Mass Ejections (CMEs) are sometimes deflected during their propagation. This deflection may be the consequence of interaction between a CME and a coronal hole or the solar wind. We analyze 44 halo-CMEs whose deflection angle exceeds 90 degrees. The coronal magnetic field configuration is computed from daily […]
