Realization of giant elastocaloric cooling at cryogenic temperatures in TmVO$_4$ via a strain load/unload technique

Posted by klaurent Caltech

Kavli Affiliate: Linda Ye| Summary:The adiabatic elastocaloric effect relates changes in the strain that a material experiences to resulting changes in its temperature. While elastocaloric materials have been utilized for cooling in room temperature applications, the use of such materials for cryogenic cooling remains relatively unexplored. Here, we use a strain load/unload technique at low […]

S-dual of Hamiltonian $mathbf G$ spaces and relative Langlands duality

Posted by klaurent Tokyo

Kavli Affiliate: Hiraku Nakajima | Summary:The S-dual $(mathbf G^veecurvearrowrightmathbf M^vee)$ of the pair $(mathbf Gcurvearrowrightmathbf M)$ of a smooth affine algebraic symplectic manifold $mathbf M$ with hamiltonian action of a complex reductive group $mathbf G$ was introduced implicitly in [arXiv:1706.02112] and explicitly in [arXiv:1807.09038] under the cotangent type assumption. The definition was a modification of […]

Non-Monotonic Size-Dependent Exciton Radiative Lifetime in CsPbBr3 Nanocrystals

Posted by klaurent Berkeley

Kavli Affiliate: Paul Alivisatos | Summary:Lead-halide perovskite nanocrystals have recently emerged as desirable optical materials for applications such as coherent quantum light emitters and solid-state laser cooling due to their short radiative lifetime and near-unity photoluminescence quantum yield. Here, we investigate the effect of CsPbBr3 nanocrystal size on the radiative lifetime under ambient conditions. High-quality […]
