Incoherent excitation of coherent Higgs oscillations in superconductors
نویسندگان
چکیده
We investigate theoretically the excitation of Higgs oscillations order parameter in superconductors by incoherent short pulses light with frequency much larger than superconducting gap. The amplitude mode is controlled a single which determined total number quasiparticles excited pulse. This fact can be traced back to universality shape light-induced quasiparticle cascade at energy below Debye and above

Coherent versus incoherent excitation energy transfer in molecular systems.
We investigate the Markovian limit of a polaronic quantum master equation for coherent resonance energy transfer proposed recently by Jang et al. [J. Chem. Phys. 129, 101104 (2008)]. An expression for the rate of excitation energy transfer (EET) is derived and shown to exhibit both coherent and incoherent contributions. We then apply this theory to calculated EET rates for model dimer systems, ...
متن کاملExciton dynamics in photosynthetic complexes: excitation by coherent and incoherent light
In this paper, we consider the dynamics of a molecular system subjected to external pumping by a light source. Within a completely quantum mechanical treatment, we derive a general formula, which enables us to assess the effects of different light properties on the photo-induced dynamics of excitations in a molecular system. We show that, once the properties of light are known in terms of a cer...
متن کاملCoherent oscillations and incoherent tunneling in a one-dimensional asymmetric double-well potential.
For a model one-dimensional asymmetric double-well potential we calculated the so-called survival probability (i.e., the probability for a particle initially localized in one well to remain there). We use a semiclassical (WKB) solution of the Schrödinger equation. It is shown that behavior essentially depends on transition probability, and on a dimensionless parameter Lambda that is a ratio of ...
متن کاملExcitation of plasma oscillations by moving Josephson vortices in layered superconductors
Electric and magnetic fields created by moving uniform lattice of Josephson vortices in the magnetic field parallel to the layers are calculated in the frame of exactly solvable model. At large velocities of the vortex lattice the plasma oscillations of superconducting electrons are excited by vortex motion, this results in interference features in I-V curves at low temperatures. The spectrum o...
متن کاملPlasma Oscillations in Layered Superconductors
Very soon after publication of the famous BCS work explaining the puzzle of the superconductivity, N.N. Bogolyubov and coworkers [1] have proposed their version of the theory. One of new results they have obtained was the discovery of a collective mode an oscillation of the Cooper pair density with the energy smaller than 2∆. P.W. Anderson has indicated that this collective mode can not be foun...
