 12:00 - 13:15     Analysis SeminarQuantum version of Lau-Paterson's result on amenable unitary co-representationsSchool MATHEMATICSIn the talk, we initiate an investigation of stable states with respect to unitary co-representations $U$ of locally compact quantum groups ${\Bbb G}$ on Hilbert spaces $H$; in particular, we study the subject on the multiplicative unitary operator $W_{\Bbb G}$ of ${\Bbb G}$ with some examples on locally compact quantum groups arising from discrete groups and compact groups. As the main result, we consider the one co-dimensional Hilbert subspace of $H$ associated to a suitable vector $\eta$, to present an operator theoretic characterization of stable states with respect to a related unitary co- ...

Graphene molecules constitute e ective models of graphene confined over a limited region. ff They are well defined cutouts or model compounds of graphene and graphene nanoribbons. Due to confinement, the electronic and vibrational properties of graphene molecules can be< ...

In this method, the energy of y-rays is dependent on the laser and electron energy and the range of energy is from keV to tens of MeV. In a sufficiently narrow backscattering angle, the y-rays are nearly monochromatic. Recently there have been several attempts to produce y-ray beams by laser Compton scattering from relativistic electrons. The aim of producing high-energy y-rays in a MeV ranges is for the nuclear physics researches and for the beam diagnostic of the electron beam circulating in the storage ring, another for medical ap ...
