The N M R spectroscopy of molecules undergoing rapid exchange between diamagnetic and paramagnetic environments is well understood and is exemplified in studies of fast electron transfer between an or...
Nanostructured Singlet Fission Photovoltaics Subject to Triplet-Charge Annihilation
singlet exciton fission photovoltaic triplet charge pentacene
2014/8/21
Singlet exciton fission is an efficient multiple-exciton generation process that is vulnerable to a characteristic loss process: triplet-charge annihilation. This loss process is characterized in sing...

2014/8/21
Exciton fission is a process that occurs in certain organic materials whereby one singlet exciton splits into two independent triplets. In photovoltaic devices these two triplet excitons can each gene...
Strong Electroweak Phase Transitions in the Standard Model with a Singlet
Strong Electroweak Phase Transitions Standard Model Singlet
2011/10/14
It is well known that the electroweak phase transition (EWPhT) in extensions of the Standard Model with one real scalar singlet can be first-order for realistic values of the Higgs mass. We revisit th...

Spin-Singlet Quantum Hall States Jack Polynomials Prescribed Symmetry
2011/10/8
Abstract: We show that a large class of bosonic spin-singlet Fractional Quantum Hall model wave-functions and their quasi-hole excitations can be written in terms of Jack polynomials with a prescribed...

Light dark matter the singlet-extended MSSM
2011/1/13
We discuss the possibility of light dark matter in a general singlet extension of the MSSM. Singlino LSPs with masses of a few GeV can explain the signals reported by the CRESST, CoGeNT and possibly ...
We propose Singlet Stabilized Minimal Gauge Mediation as a simple ISS-based model of Direct Gauge Mediation which avoids both light gauginos and Landau poles. The hidden sector is a massive s-confinin...

Triplet-singlet conversion ground state molecules
2010/11/17
We propose a process to convert ultracold metastable Cs$_2$ molecules in their lowest triplet state into (singlet) ground state molecules in their lowest vibrational levels. Molecules are first pumpe...

Analyzing Correlations spin-1/2 particles Singlet pairs
2010/10/29
We review the computation of correlations of successive projections of the spin onto axes for spin-1/2 particles and EPRB pairs (in the Singlet state). We assume forms of Realism (at least as general ...

2010/10/18
We report measurements of the optical properties of the 1042 nm transition of negativelycharged
Nitrogen-Vacancy (NV) centers in type 1b diamond. The results indicate that the upper level of this tra...

The entanglement spectrum, i.e., the full distribution of Schmidt eigenvalues of the reduced
density matrix, contains more information than the conventional entanglement entropy and has been studied ...
