Stiff, Strong, Zero Thermal Expansion Lattices via Material Hierarchy
For engineering applications where tight dimensional tolerances are required, or for applications where materials are subjected to a wide range of temperatures it becomes desirable to reduce a material’s coefficient of thermal expansion. By carefully designing lattice microstructures, zero thermal expansion can be achieved. This work describes lattice microstructures that achieve zero expansion...
متن کاملDensity near zero
Let $S$ be a dense subsemigroup of $(0,+infty)$. In this paper, we state definition of thick near zero, and also we will introduce a definition that is equivalent to the definition of piecewise syndetic near zero which presented by Hindman and Leader in [6]. We define density near zero for subsets of $S$ by a collection of nonempty finite subsets of $S$ and we investigate the conditions un...
متن کاملThermal Bubble Diagrams Near Zero Energy
The zero four-momentum and equal mass limits are taken for the bubble diagram of scalar fields. It is seen that RTF and ITF are in complete agreement. However contributions from this diagram to both retarded and time-ordered functions do depend on the order of the limits and can be infinite in some cases. This shows explicitly that the relation between the free energy and a derivative expansion...
متن کاملThermal Bosonic Green Functions Near Zero Energy
The properties of the various types of bosonic Green functions at finite temperature in the zero energy limit are considered in the light of recent work. Nous discutons, à la lumière de récents travaux, des propriétés de certains types de fonctions de Green à température finie, dans le cas limite où l’énergie est nulle.
متن کاملNovel quantum criticality in CeRu2Si2 near absolute zero observed by thermal expansion and magnetostriction.
We report linear thermal expansion and magnetostriction measurements for CeRu2Si2 in magnetic fields up to 52.6 mT and at temperatures down to 1 mK. At high temperatures, this compound showed Landau-Fermi-liquid behavior: The linear thermal expansion coefficient and the magnetostriction coefficient were proportional to the temperature and magnetic field, respectively. In contrast, a pronounced ...
