Coherence oscillations measured in two-dimensional (2D) electronic spectra of pigment-protein complexes may have electronic, vibrational, or mixed-character vibronic origins, which depend on the degree of electronic-vibrational mixing. Oscillations from intrapigment vibrations can obscure the inter-site coherence lifetime of interest in elucidating the mechanisms of energy transfer in photosynt...

Abstract. We obtain explicit analytical expressions for the quadrature variances and the photon distribution functions of the electromagnetic field modes excited from vacuum or thermal states due to the non-stationary Casimir effect in an ideal one-dimensional Fabry–Perot cavity with vibrating walls, provided the frequency of vibrations is close to a multiple frequency of the fundamental unpert...

Ultrasonics complex vibrations with twoor three-dimensional vibration locus are effective for various applications. Various high-frequency and complex-vibration systems have been proposed and studied. The applications include ultrasonic direct welding of LSI, semiconductor chips without adhesive or solder, ultrasonic seam welding of thin metal plates, ultrasonic welding of thick metal specimens...

in this paper, an analytical study of the forced vibrations of hexapod table is studied. considering external force as a time sinusoid force, forced vibrations of the platform are investigated. resonance frequencies and vibrations of the moving platform are also calculated in different directions. the results of the analytical approach are verified using fem simulation. modelling the harmonic m...

Large and sparse rational eigenproblems where the rational term is of low rank k arise in vibrations of fluid–solid structures and of plates with elastically attached loads. Exploiting model order reduction techniques, namely the Padé approximation via block Lanczos method, problems of this type can be reduced to k–dimensional rational eigenproblems which can be solved efficiently by safeguarde...

In this paper, the behavior of free vibrations and buckling of the sandwich panel with a flexible core was investigated using a new improved ‎high-order sandwich panel theory. In this theory, equations of motion were formulated based on shear stresses in the core. First-order shear deformation theory was ‎applied for the procedures. In this theory, for the first time, incompatibility problem of...

We report a solution of the tilted-axis cranked HFB equation for 164Hf, which shows wobbling motion coupled to gamma vibration at high spin (J ≃ 60h̄). Possible anharmonicity and splitting of energy levels are also discussed as a consequence of the wobbling motion with large amplitude. PACS number(s): 27.70.+q, 21.10.-k In understanding the excited states of a quantum many-body system with finit...
