Outline of Final Research Achievements

We clarified the peculiar features of the quantum state of Bloch electrons under the influence of oscillating elctromagnetic fields. It is found that, by choosing the ratio of the amplitude and the frequency of the field, it is possible to reduce, or even collapse the band gap of the Bloch states. It has been demonstrated that we can control the Bloch-Zener tunneling of electrons by applying this principle. Furthermore, we have shown that the morphology of the Dirac cone in graphene can be changed drastically by irradiating electromagnetic fields with various polarization. As an example, we have shown that the Dirac cone is deformed into Dirac wedge, where a one-dimensional manifold of zero-gap state emerges.
We have formulated the theory for the generation and detection of coherent phonons in bulk crystals. It was shown that by using the phase-locked double pulses, the coherence of the electron-phonon coupled state can be controlled and observed via the transient reflection modulation.
