报告摘要: We discover surprising consequences of well-known quantum effects such as zero-point energies, superposition and interferences of quantum states, decoherence. The examples include a new type of chemical bonding: “vibrational bonding” stabilizes BrMuBr due to effects of vibrational zero point energies (Muonium Mu is the light isotope of hydrogen, mMu = mH/9). The large mass ratio ena...

报告摘要: I will present a world view for electrons in crystals based the semiclassical dynamics and describe how the Berry curvatures modify the thermodynamic and transport properties.   I will then extend this point of view to spacetime crystals by introducing the concept of an event wavepacket, the quantum version of the classical event point in spacetime.  I will also describe spatial and t...
