WebAug 2, 1999 · We propose to use periodically spaced, curved optical waveguides for observation of optical Bloch oscillations. The refractive index distribution in this system is equivalent to the sum of a periodic term resulting from the equal spacing of the waveguides and a linear ramp, created by the curvature. WebBloch oscillations are an intriguing concept of solid state physics. When an electron experiences the force of an electric field in a periodic potential, the resulting dynamics is …

Chiral Bloch oscillation and nontrivial topology in a ladder lattice ...

WebIn general, Bloch oscillations are a consequence of the periodic structure of the lattice potential and the existence of a maximum value of the Bloch wave vector . A constant force results in the acceleration of the particle until the edge of the first Brillouin zone is reached. WebApr 10, 2024 · Accelerating a quantum particle on an ideal periodic lattice potential leads to oscillatory motion instead of a net drift. This counter-intuitive phenomenon, known as Bloch oscillations (BOs), has ... primary advertising objectives

Webexciton transitions, Bloch oscillations develop as quantum interference of the excited electron WS states. Esaki & Tsu (1970) proposed to utilize Bloch oscillations as a source … WebJul 5, 2006 · The dynamics of quantum particles shows a coherent superposition of Bloch oscillations and Zener tunnelling between the sub-bands, a Bloch–Zener oscillation. Such a system is modelled by a tight-binding Hamiltonian which is a system of two minibands with an easily controllable gap. WebA . quantum gate. is just a unitary linear operation U on the states of the qubits. For one qubit, a gate operation can be visualized as a rotation on the Bloch sphere. primary advent calendar
