Decay of transmon qubit in a broadband one-dimensional cavity
Ya. S. Greenberg, A. A. Shtygashev, O. V. Kibis
We investigate the decay dynamics of a three-level artificial atom, a superconducting transmon qubit, weakly coupled to a continuum of modes in a broadband, one-dimensional cavity.…

Quantum correlations of the photon fields in a waveguide quantum electrodynamics
Ya. S. Greenberg. O. A. Chuikin, A. G. Moiseev, A. A. Shtygashev
We present a time-dependent quantum calculations of the first order and second order photon correlation functions for the scattering of a single-photon pulse on a two-level atom (q…

Fast pulsed photoemission from a double quantum well on a dielectric substrate as a dynamic process of inverse LEED leading to the generation of a charge and current density wave
Yu. G. Peisakhovich, A. A. Shtygashev
Within the framework of the rigorous quantum theory of the atomic photoeffect and the scenario of photoemission from a crystal as an inverse LEED process, pulsed photoemission from…
