Abstract：The past decade has witnessed a surge of interest in exploring emergent particles in condensed matter systems. Novel particles, emerged as excitations around exotic band degeneracy points, continue to be reported in real materials and artificially engineered systems, but so far, we do not have a complete picture on all possible types of particles that can be achieved. Here, via systematic symmetry analysis and modeling, we accomplish a complete list of all possible particles in time reversal-invariant systems. This includes both spinful particles such as electron quasiparticles in solids, and spinless particles such as phonons or even excitations in electric-circuit and mechanical networks. We establish detailed correspondence between the particle, the symmetry condition, the effective model, and the topological character. This obtained encyclopedia concludes the search for novel emergent particles and provides concrete guidance to achieve them in physical systems.

Abstract： Creativity is an interwoven system, encompassing individuals, groups, society, culture, etc. Since creativity is a system, the cultivation of creativity should also be systematic. We integrated some creativity-relevant theories to generate practical advice on the challenges of supporting creativity within the classroom. Based on earlier research on creativity, we put forth the “Butterfly Theory of Nurturing Creativity” to give a bird’s eye view of nurturing creativity. In this theory, the core and premise of being creative are to have creative impulses or creative dynamics (i.e., dynamic systems). We summarized the conditions supporting the dynamic systems into “two forewings” named capability and vitality (i.e., the support system). At the level of capability, creativity calls for general cognitive ability, multimethod enlightenment, attention to metacognition, and efficient knowledge information management. At the level of vitality, creative dynamics also relies on the satisfaction of basic psychological needs, the healthy development of personal traits, and reasonably supportive social interaction in an inclusively social and cultural environment. Besides, if an individual wants to fly freely in a creative life, he also needs “two hindwings” (conducting daily creative thinking and problem solving; forming creative habits and a creative personality) that are constantly improved in daily life to adjust the balance (i.e., regulating system). People who are creative show motivation to make novel and appropriate products for their domains of interest. Creativity cannot be taught unless teachers find ways to intrigue their students’ creative impulses. Intrinsic motivation, like interest, is the greatest autonomous motivator. The key topics of this paper are to find what the essence of interest or fun is and how to raise it. Combining theory with practice, this paper also shows a general way to activate fun or interest in the classroom.
