Resonance Kondo Tunneling through a Double Quantum Dot at Finite Bias

, 2003
It is shown that the resonance Kondo tunneling through a double quantum dot (DQD) with even occupation and singlet ground state may arise at a strong bias, which compensates the energy of singlet/triplet excitation.

Lowering of the singlet-triplet energy gap via intramolecular exciton-exciton coupling

Nature Communications
Organic dyes typically have electronically excited states of both singlet and triplet multiplicity. Controlling the energy difference between these states is a key factor for making efficient organic light emitting diodes and triplet sensitizers, which ...

Theory of Charge Kondo Effect on Pair Hopping Mechanism

, 2012
A new microscopic model of the charge Kondo effect is proposed, and is studied on the basis of a numerical renormalization group calculations. It is shown that the charge Kondo effect is caused by a pair hopping interaction between the conduction band ...

Exact ground states for a class of one-dimensional frustrated quantum spin models

, 1999
We have found the exact ground state for two frustrated quantum spin-1/2 models on a linear chain. The first model describes ferromagnet- antiferromagnet transition point. The singlet state at this point has double-spiral ordering.

Theoretical study of the absorption spectra of the sodium dimer

, 2000
Absorption of radiation from the sodium dimer molecular states correlating to Na(3s)-Na(3s) is investigated theoretically. Vibrational bound and continuum transitions from the singlet X Sigma-g+ state to the first excited singlet A Sigma-u+ and singlet B

Singlet-Triplet Physics and Shell Filling in Carbon Nanotube Double Quantum Dots

, 2007
An artifcial two-atomic molecule, also called a double quantum dot (DQD), is an ideal system for exploring few electron physics. Spin-entanglement between just two electrons can be explored in such systems where singlet and triplet states are accessible.

Machine learning photodynamics decode multiple singlet fission channels in pentacene crystal

Nature Communications
Crystalline pentacene is a model solid-state light-harvesting material because its quantum efficiencies exceed 100% via ultrafast singlet fission. The singlet fission mechanism in pentacene crystals is disputed due to insufficient electronic information ...
