Understanding Photoinduced Symmetry- Breaking Charge Separation
Symmetry-breaking charge separation (SB-CS) is a photoinduced electron transfer reaction in which the chromophore acts as both the acceptor and the donor.

Spin-charge separation in ultra-cold quantum gases [PDF]
We investigate the physical properties of quasi-1D quantum gases of fermion atoms confined in harmonic traps. Using the fact that for a homogeneous gas, the low energy properties are exactly described by a Luttinger model, we analyze the nature and ...

Spontaneous Separation of Charged Grains [PDF]
In 1867, Lord Kelvin described an experiment in which two streams of water droplets were connected so that each stream amplified the charge on the second stream [W. Thomson, Proc. R. Soc. London 16, 67 (1867)]. We present here a complementary effect in flowing grains that spontaneously separates similar and well-mixed grains into two charged streams of

Separation of spin and charge in paired spin-singlet quantum Hall states [PDF]
We propose a series of paired spin-singlet quantum Hall states, which exhibit a separation of spin and charge degrees of freedom. The fundamental excitations over these states, which have filling fraction \nu=2/(2m+1) with m an odd integer, are spinons ...

Access Charges, Vertical Separation, and Lobbying [PDF]
We examine how vertical separation affects the lobbying activities for the access charge of essential facilities. First, when investigating a model where the number of new entrants is fixed, we find that vertical separation either increases or decreases the access charge, and that this depends on the relative efficiency between the incumbent and the ...

Charge separation in organic photovoltaic cells [PDF]
We consider a simple model for the geminate electron-hole separation process in organic photovoltaic cells, in order to illustrate the influence of dimensionality of conducting channels on the efficiency of the process. The Miller-Abrahams expression for

Probing spin-charge separation in a Tomonaga-Luttinger liquid [PDF]
In a one-dimensional (1D) system of interacting electrons, excitations of spin and charge travel at different speeds, according to the theory of a Tomonaga-Luttinger Liquid (TLL) at low energies.

Femtosecond transient absorption spectroscopy is performed to assess bridge effects on energy transfer and charge separation in molecular junctions. A short, conjugated bridge can facilitate charge separation from both donor and acceptor, whereas in ...

Balancing charge generation and voltage loss toward efficient nonfullerene organic solar cells
The inherently large exciton binding energy for photo-generated electron-hole pairs has hindered the charge generation and photons utilization in organic solar cells (OSCs) for decades, thereby constraining their performance to an inferior regime with ...
