Manipulating single enzymes by an external harmonic force
Michael A. Lomholt, Michael Urbakh, Ralf Metzler +1
We study a Michaelis-Menten reaction for a single two-state enzyme molecule, whose transition rates between the two conformations are modulated by an harmonically oscillating exter…
Homochirality in an early peptide world
Axel Brandenburg, Harry J. Lehto, Kirsi M. Lehto
A recently proposed model of non-autocatalytic reactions in dipeptide reactions leading to spontaneous symmetry breaking and homochirality is examined. The model is governed by act…
Understanding nuclear "pasta": current status and future prospects
Gentaro Watanabe
In cores of supernovae and crusts of neutron stars, nuclei can adopt interesting shapes, such as rods or slabs, etc., which are referred to as nuclear "pasta." In recent years, we…
Fear and its implications for stock markets
Ingve Simonsen, Peter Toke Heden Ahlgren, Mogens H. Jensen +2
The value of stocks, indices and other assets, are examples of stochastic processes with unpredictable dynamics. In this paper, we discuss asymmetries in short term price movements…
Non-perturbative Gravity, Hagedorn Bounce & CMB
Tirthabir Biswas, Robert Brandenberger, Anupam Mazumdar +1
In hep-th/0508194 it was shown how non-perturbative corrections to gravity can resolve the big bang singularity, leading to a bouncing universe. Depending on the scale of the non-p…
Energy-dependent effective interactions for dilute many-body systems
A. Collin, P. Massignan, C. J. Pethick
We address the issue of determining an effective two-body interaction for mean-field calculations of energies of many-body systems. We show that the effective interaction is propor…
