Effects of applied fields on quantum coupled double-well systems
Hideo Hasegawa
Effects of time-dependent applied fields on quantum coupled double-well (DW) systems with Razavy's hyperbolic potential have been studied. By solving the Schrödinger equation for t…
Dynamical properties of an exactly solvable coupled quantum double-well system: The evolution speed and entanglement
Hideo Hasegawa
We have studied dynamical properties of an exactly solvable quantum coupled double-well (DW) systems with Razavy's hyperbolic potential. With the use of four kinds of initial wavep…
Wavepacket dynamics in a quantum double-well system with Razavy's potential coupled to a harmonic oscillator
Hideo Hasegawa
We have studied wavepacket dynamics in the Razavy hyperbolic double-well (DW) potential which is coupled to a harmonic oscillator (HO) by linear and quadratic interactions. Taking…
Quantum tunneling and evolution speed in an exactly solvable coupled double-well system
Hideo Hasegawa
Exact analytical calculations of eigenvalues and eigenstates are presented for quantum coupled double-well (DW) systems with Razavy's hyperbolic potential. With the use of four kin…
