We investigate symmetrically coupled double quantum dots via the hierarchical equations of motion method and propose a novel zero-energy mode (ZEM) at a temperature above the spin singlet–triplet transition temperature.Owing to the resonance of electron quasi-particle and hole quasi-particle,ZEM has a peak at ω = 0 in the spectral density function.We further examine the effect of the magnetic field on the ZEM,where an entanglement of spin and charge has been determined;therefore,the magnetic field can split the ZEM in the spectra.
