Tunnelling of Quantum Spins

Europhysics Letters (EPL), 1986
A WKB formalism is presented to describe the quantum dynamics, including tunnelling, of a single spin with large spin quantum number. This is of particular relevance to the treatment of Hamiltonians with a large anisotropy. For a wide class of Hamiltonians we obtain the eigenstates and tunnelling rates and show the universal dependence of the latter ...

Resonant tunnelling via InAs self-organized quantum dot states

Microelectronic Engineering, 1998
InAs quantum dots formed by submonolayer insertion of InAs into the GaAs quantum well of a GaAs/AlAs double barrier resonant tunnelling structure were studied.

Quantum complexity associated with tunneling

Quantum Information and Computation, 2019
We use a one dimensional model of a square barrier embedded in an infinite potential well to demonstrate that tunneling leads to a complex behavior of the wave function and that the degree of complexity may be quantified by use of a locally defined spatial entropy function defined by S=-\int |\Psi(x,t)|^2 \ln |\Psi(x,t)|^2 dx .

Photoinduced macroscopic quantum tunneling

Physical Review B, 1985
Recently there has been interest in macroscopic systems which can be described in terms of the quantum dynamics of the same collective variables which describe their classical behavior. In particular, there has been considerable interest in the following questions: (1) Is it possible to observe unambiguous evidence of the quantum-mechanical nature of a

Quantum tunneling, dissipation, and fluctuations

Physical Review Letters, 1986
A theory of quantum tunneling with dissipation is constructed. The frequency-dependent transmission coefficient is calculated at zero and finite temperatures. A fluctuation-dissipation theorem for tunneling particles is derived.
