Correlated Charge Transport in an Organic Coulomb Glass
Advanced Materials, EarlyView.ABSTRACT Advances in the development of organic field‐effect transistors (OFETs), electrically gated organic semiconductors (EGOFETs), and organic electrochemical transistors (OECTs) allow for the operation of these devices at very high charge‐carrier densities, where Coulomb interactions between carriers can be expected to become significant.

Hints of the Dark World: Looking for the Particle Nature of Dark Matter [PDF]
The particle nature of dark matter remains one of the largest unanswered questions in the field. Outside of its abundance, most of its properties are unknown and broadly constrained.

, 2004 This biennial Review summarizes much of Particle Physics. Using data from previous editions, plus 1726 new measurements from 512 papers, we list, evaluate, and average measured properties of gauge bosons, leptons, quarks, mesons, and baryons.

Advanced Materials, EarlyView.The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Particle/Antiparticle Nature of Light Dark Matter in Direct Detection [PDF]
, 2019 In the last century, astronomers have concluded that the luminous mass in the Universe impossibly can be responsible for the huge gravitational pull observed in stellar and galactic systems.

Detecting particle dark matter signatures by cross-correlating γ-ray anisotropies with weak lensing [PDF]
, 2016 The underlying nature of dark matter still represents one of the fundamental questions in contemporary cosmology. Although observations well agree with its description in terms of a new fundamental particle, neither direct nor indirect signatures of its ...

Conformal freeze-in from neutrino portal
Journal of High Energy PhysicsWe study a scenario where a dark sector, described by a Conformal Field Theory (CFT), interacts with the Standard Model through the neutrino portal. In this setup, conformal invariance breaks below the electroweak scale, causing the theory to transition ...

Higgs-portal spin-1 dark matter with parity-violating interaction
Journal of High Energy PhysicsWe introduce the spin-1 U(1) X gauged field X with Z 2 odd dark parity to evade the current strong constraints on kinetic mixing. Then, X becomes stable and a candidate for the dark matter. The lowest mass dimension of interaction is six, and the type is
