Title: Density matrix approach to photon-assisted tunneling in the transfer Hamiltonian formalism

Abstract

The transfer Hamiltonian tunneling current is derived in a time-dependent density matrix formulation and is used to examine photon-assisted tunneling. Bardeen's tunneling expression arises as the result of first-order perturbation theory in a mean-field expansion of the density matrix. Photon-assisted tunneling from confined electromagnetic fields in the forbidden tunnel barrier region occurs due to time-varying polarization and wave-function overlap in the gap which leads to a nonzero tunneling current in asymmetric device structures, even in an unbiased state. The photon energy is seen to act as an effective temperature-dependent bias in a uniform barrier asymmetric tunneling example problem. Higher-order terms in the density matrix expansion give rise to multiphoton enhanced tunneling currents that can be considered an extension of nonlinear optics where the nonlinear conductance plays a similar role as the nonlinear susceptibilities in the continuity equations.

Photon-assisted transmission through an oscillating quantum well: A transfer-matrix approach to coherent destruction of tunneling

Journal Article Wagner, M - Physical Review A; (United States)

Based on a trasfer-matrix formalism, photon-assisted tunneling is studied in a strongly driven double-barrier tunneling diode. Two scenarios are considered: A driving potential [ital V][sub 1]cos([omega][ital t]) acting on the central quantum well, which may be realized with electrostatic gates close to the quantum well, and a driving electric field across the diode generated by a laser field. Strong quenching of the transmission probability is found for certain parameters [l brace][ital V][sub 1],[omega][r brace] of the driving field, which can be explained in terms of zeros of fractional Bessel functions, [ital J][sub [plus minus][nu]]([gamma][ital V][sub 1]/[h bar][omega]), where [gamma] ismore »« less

The Harper–Hofstadter Hamiltonian and conical diffraction in photonic lattices with grating assisted tunneling

Journal Article Dubček, Tena ; Lelas, Karlo ; Jukić, Dario ; ... - New Journal of Physics

Here we propose the realization of a grating assisted tunneling scheme for tunable synthetic magnetic fields in optically induced one- and two-dimensional dielectric photonic lattices. As a signature of the synthetic magnetic fields, we demonstrate conical diffraction patterns in particular realization of these lattices, which possess Dirac points in k-space. Lastly, we compare the light propagation in these realistic (continuous) systems with the evolution in discrete models representing the Harper-Hofstadter Hamiltonian, and obtain excellent agreement.

Density-Matrix Model for Photon-Driven Transport in Quantum Cascade Lasers

Journal Article Soleimanikahnoj, S. ; King, Michelle L. ; Knezevic, I. - Physical Review Applied

In this report we develop a time-dependent density-matrix model to study photon-assisted (PA) electron transport in quantum cascade lasers. The Markovian equation of motion for the density matrix in the presence of an optical field is solved for an arbitrary field amplitude. Level-broadening terms emerge from microscopic Hamiltonians and supplant the need for empirical parameters that are often employed in related approaches. We show that, in quantum cascade lasers with diagonal design, photon resonances have a pronounced impact on electron dynamics around and above the lasing threshold, an effect that stems from the large spatial separation between the upper andmore »« less

Photon-assisted tunneling through a topological superconductor with Majorana bound states

Journal Article Tang, Han-Zhao ; Zhang, Ying-Tao ; Liu, Jian-Jun ; ... - AIP Advances

Employing the Keldysh Nonequilibrium Green’s function method, we investigate time-dependent transport through a topological superconductor with Majorana bound states in the presence of a high frequency microwave field. It is found that Majorana bound states driven by photon-assisted tunneling can absorb(emit) photons and the resulting photon-assisted tunneling side band peaks can split the Majorana bound state that then appears at non-zero bias. This splitting breaks from the current opinion that Majorana bound states appear only at zero bias and thus provides a new experimental method for detecting Majorana bound states in the Non-zero-energy mode. We not only demonstrate that themore »« less

Defect assistant band alignment transition from staggered to broken gap in mixed As/Sb tunnel field effect transistor heterostructure

Journal Article Zhu, Y. ; Jain, N. ; Vijayaraghavan, S. ; ... - Journal of Applied Physics

The compositional dependence of effective tunneling barrier height (E{sub beff}) and defect assisted band alignment transition from staggered gap to broken gap in GaAsSb/InGaAs n-channel tunnel field effect transistor (TFET) structures were demonstrated by x-ray photoelectron spectroscopy (XPS). High-resolution x-ray diffraction measurements revealed that the active layers are internally lattice matched. The evolution of defect properties was evaluated using cross-sectional transmission electron microscopy. The defect density at the source/channel heterointerface was controlled by changing the interface properties during growth. By increasing indium (In) and antimony (Sb) alloy compositions from 65% to 70% in In{sub x}Ga{sub 1-x}As and 60% to 65%more »« less
