Web21 Jan 2015 · The SPT phases in free fermion systems, like topological insulators, can be classified by K-theory. However, it is not yet known what SPT phases exist in general interacting systems. In this talk, I will first present a systematic way to construct SPT phases in interacting bosonic systems, which allows us to identify many new SPT phases. WebThe Standard Penetration Test (SPT Test) is one type of in-situ soil test and It is conducted to determine the geotechnical engineering properties of subsurface soils, especially for …

This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 and … See more A borehole shall be advanced incrementally to permit intermittent or continuous sampling. Intervals are typically 1.5 m (5 ft) or less in homogeneous strata. Tests and sampling should be done at … See more The great merit of the test is that it is simple, inexpensive, and widely used. The soil strength parameters which can be inferred from SPT results are approximate, but may give a useful guide in ground conditions where more advanced laboratory testing is … See more • Cone penetration test • Geotechnical investigation • Soil mechanics See more Despite its many flaws, it is usual practice to correlate SPT results with soil properties relevant for geotechnical engineering design. SPT results are in-situ field measurements … See more The standard penetration test recovers a highly disturbed sample, which is generally not suitable for tests which measure properties of the in-situ soil structure, such as density, strength, and consolidation characteristics. To overcome this limitation, the test is … See more
Symmetry-protected topological (SPT) order is a kind of order in zero-temperature quantum-mechanical states of matter that have a symmetry and a finite energy gap. To derive the results in a most-invariant way, renormalization group methods are used (leading to equivalence classes corresponding to certain fixed points). The SPT order has the following defining properties: WebIts definition is derived from the Mohr-Coulomb failure criterion and it is used to describe the friction shear resistance of soils together with the normal effective stress. In the stress …
