THE OPTICAL POLARON IN A TUNABLE POTENTIAL WELL
Modern Physics Letters B, 2011The optical polaron confined to quantum well with tunable dimensions is investigated within the framework of a variational technique intending to give a unified characterization of problem for all the coupling strengths. The ground state energy and the number of phonons around the electron are studied as a function of the degree of confinement of the ...

Resistance resonance in coupled potential wells
Physical Review Letters, 1990A new resistance resonance effect based on the quantum-mechanical delocalization of electrons in a symmetric-double-well potential is presented. We show that changing the symmetry of the potential profile gives rise to a resistance peak if the transport properties of the two wells are different.

On a problem of potential wells
1995This paper gives a result for the existence of a minimizer for an energy functional of the kind \(\int_\Omega g(\nabla u(x))dx\), where \(g\) is nonnegative and is zero only on potential wells described by rotations of finitely many matrices \(A_1,\dots,A_r\). The problem of finding a minimizer is than equivalent to solving the differential inclusion \[

Square-well potential by an algebraic approach
Physical Review A, 1986The spectrum-generating algebra for the problem of a particle in a potential well is shown to be su(1,1). Both the infinitely deep and finite square wells are considered. The generators can also be derived via a systematic procedure for determining the time-dependent constants of the motion. The coherent states are explicitly constructed.

The effective classical potential of the double-well potential
Chemical Physics Letters, 1987Abstract We calculate the “effective classical potential” via Monte Carlo simulation and study the accuracy of a recently proposed approximation for it. The approximation is found to be excellent down to very low temperatures T ⪆ 1 10 .
