Manifestation of the odd-frequency spin-triplet pairing state in diffusive ferromagnet / superconductor junctions [PDF]

, 2006
Using the quasiclassical Green's function formalism, we study the influence of the odd-frequency spin-triplet superconductivity on the local density of states (LDOS) in a diffusive ferromagnet (DF) attached to a superconductor.

Preparation Efficiency of Singlet States in Multi-spin Systems with Different Coupling Configurations

Chinese Journal of Magnetic Resonance
Nuclear spin singlet is a special quantum state that lasts longer than T1 and can be used to study slow diffusion and motion between molecules. The preparation of singlet states is the key to their successful application.

Dissociative Autoionization in (1+2)-photon Above Threshold Excitation of H2 Molecules [PDF]

, 1999
We have theoretically studied the effect of dissociative autoionization on the photoelectron energy spectrum in (1+2)-photon above threshold ionization(ATI) of H2 molecules. We have considered excitation from the ground state X-singlet-Sigma-g+(v=0,j) to

Singlet fission in tetracene: an excited state analysis [PDF]

Molecular Physics, 2020
Singlet fission is a potential mechanism to enhance the performance of current solar cells. However, the actual mechanism is still a matter of debate, with charge transfer states believed to play an essential role. The probability of the overall process can be related to the electronic coupling between the electronic states.

Concurrence vs. purity: Influence of local channels on Bell states of two qubits

, 2005
We analyze how a maximally entangled state of two-qubits (e.g., the singlet $\psi_s$) is affected by action of local channels described by completely positive maps $\cE$ .

Correlated electron transport through double quantum dots coupled to normal and superconducting leads

, 2010
We study Andreev transport through double quantum dots connected in series normal and superconducting (SC) leads, using the numerical renormalization group.

Mass of the singlet P state

Physics Letters B, 1992
Abstract We show that the mass of the 1P1 charmonium state can be reliably calculated by gluon exchange. Remarkably, the one-loop calculation of the mass difference between the center of gravity of the triplet and the 1P1 state is independent to this order of renormalization scheme and scale, and uniquely determined by the value of αs(mc).

Non-adiabatic charge state transitions in singlet–triplet qubits

New Journal of Physics, 2013
In double quantum dot singlet–triplet qubits, the exchange interaction is used in both quantum gate operation and the measurement of the state of the qubit. The exchange can be controlled electronically by applying gate voltage pulses.

Zhang-Rice singlets state formed by two-step oxidation for triggering water oxidation under operando conditions

Nature Communications, 2023
The Zhang-Rice singlet is known for the superconductivity of high-temperature superconductors cuprate but is rarely studied for an electrochemical catalyst.
