Large depth-of-field tracking of colloidal spheres in holographic microscopy by modeling the objective lens

Posted by klaurent Harvard

Kavli Affiliate: Vinothan Manoharan | First 5 Authors: Brian Leahy, Ronald Alexander, Caroline Martin, Solomon Barkley, Vinothan Manoharan | Summary: Holographic microscopy has developed into a powerful tool for 3D particle tracking, yielding nanometer-scale precision at high frame rates. However, current particle tracking algorithms ignore the effect of the microscope objective on the formation of […]

Observation of spin-momentum locked surface states in amorphous Bi$_{2}$Se$_{3}$

Posted by dbos Berkeley

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: , , , , | Summary: Crystalline symmetries have played a central role in the identification of topological materials. The use of symmetry indicators and band representations have enabled a classification scheme for crystalline topological materials, leading to large scale topological materials discovery. In this work we […]

Modification of electron-phonon coupling by micromachining and suspension

Posted by klaurent Caltech

Kavli Affiliate: Michael Roukes | First 5 Authors: Olli-Pentti Saira, Matthew H. Matheny, Libin Wang, Jukka Pekola, Michael Roukes | Summary: Weak electron-phonon interaction in metals at low temperatures forms the basis of operation for cryogenic hot-electron bolometers and calorimeters. Standard power laws, describing the heat flow in the majority of experiments, have been identified […]

Minimal Warm Inflation

Posted by klaurent Stanford

Kavli Affiliate: Peter W. Graham | First 5 Authors: Kim V. Berghaus, Peter W. Graham, David E. Kaplan, , | Summary: Slow-roll inflation is a successful paradigm. However we find that even a small coupling of the inflaton to other light fields can dramatically alter the dynamics and predictions of inflation. As an example, the […]

Hirota Quadratic Equations for the Gromov–Witten Invariants of $mathbb{P}_{n-2,2,2}^1$

Posted by klaurent Tokyo

Kavli Affiliate: Todor Milanov | First 5 Authors: Jipeng Cheng, Todor Milanov, , , | Summary: Fano orbifold lines are classified by the Dynkin diagrams of type $A,D,$ and $E$. It is known that the corresponding total descendant potential is a tau-function of an appropriate Kac–Wakimoto hierarchy. It is also known that in the A-case […]
