After showing that the symmetry operations of a crystal form a group, we show how to go over from this group to the space group characterizing the crystal structure on the microscopic scale, and then to the point group, which governs its macroscopic physical properties. The rigorous proof is ...
Space group, in crystallography, any of the ways in which the orientation of a crystal can be changed without seeming to change the position of its atoms. These changes may involve displacement of the whole structure along a crystallographic axis (transl

To construct a gapped TCS, we arrange p blocks in such a way that the space group of the TCS is preserved, including translation symmetries, point-group symmetries, and nonsymmorphic symmetries. The p blocks in general have open boundaries, and, being SPT themselves, gapless boundary states (...
The first is Resourcefulness (足智多谋). When the water system broke, the group had two___. They could figure out how to fix it or they could___months for supplies to be delivered from “Earth”—by which point they would be dead. So they___it themselves. The second is Imagination...

Solution method: The direct data in the BC book is used to calculate the LG IRs for standard k-points defined in the book. For a non-standard k-point, we first relate it to a standard k-point by an element which makes the space group self-conjugate and then calculate the LG IRs thr...

To further measure the performance of the model, we also introduce three metrics that are model parameters (Params), model running time (Time, in seconds), and floating-point operations per second (FLOPs). 4.3. Implementation Details In the shared feature extraction module, the CNN backbone netw...
