Self-Organization and Forces in the Mitotic Spindle

Friday September 16th, 2016 Ivan Balog 0

ABSTRACT: At the onset of division, the cell forms a spindle, a precise self-constructed micromachine composed of microtubules and the  associated proteins, which divides the chromosomes between the two nascent daughter cells. The spindle arises from self-organization of  microtubules and chromosomes, whose different types of motion help them explore the […]

GPD phenomenology and DVCS fitting – Entering the high-precision era

Friday September 16th, 2016 Ivan Balog 0

ABSTRACT:  We review the phenomenological framework for accessing Generalized Parton Distributions (GPDs) using measurements of Deeply Virtual Compton Scattering (DVCS) from a proton target. We describe various GPD models and tting procedures, emphasizing speci c challenges posed both by the internal structure and properties of the GPD functions and by their […]

Dynamical conductivity and its fluctuations along the crossover to many-body localization

Friday September 16th, 2016 Hrvoje Buljan 0

ABSTRACT: We present a numerical study of the many-body localization (MBL) phenomenon in the high-temperature limit within an anisotropic Heisenberg model with random local fields. Taking the dynamical spin conductivity σ(ω) as the test quantity, we investigate the full frequency dependence of sample-to-sample fluctuations and their scaling properties as a function […]

Efficient plasmonic emission by the quantum Čerenkov effect from hot carriers in graphene

Friday September 16th, 2016 Hrvoje Buljan 0

ABSTRACT: Graphene plasmons have been found to be an exciting plasmonic platform, thanks to their high field confinement and low phase velocity, motivating contemporary research to revisit established concepts in light–matter interaction. In a conceptual breakthrough over 80 years old, Čerenkov showed how charged particles emit shockwaves of light when moving […]
