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 […]

Elastic properties of hidden order in URu$_{text2}$Si$_{text2}$ are reproduced by a staggered nematic

Posted by klaurent Cornell

Kavli Affiliate: Brad Ramshaw | First 5 Authors: Jaron Kent-Dobias, Michael Matty, Brad Ramshaw, , | Summary: We develop a phenomenological mean field theory describing the hidden order phase in URu$_{text2}$Si$_{text2}$ as a nematic of the $text B_{text{1g}}$ representation staggered along the $c$-axis. Several experimental features are reproduced by this theory: the topology of the […]

Heliosheath Properties Measured from a Voyager 2 to Voyager 1 Transient

Posted by klaurent MIT

Kavli Affiliate: John D. Richardson | First 5 Authors: Jamie S. Rankin, David J. McComas, John D. Richardson, Nathan A. Schwadron, | 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 […]
