The model is statistical physics-like in that it makes a coarse-grained description of the growth process, reduced to three variables within the bacterial cell - the antibiotic concentration, the concentration of ribosomes bound to antibiotics and the concentration of unbound ribosomes. Furthermore, there is biological input from empirically established physiological constraints which relate the three variables. Remarkably the model can explain several observations concerning antibiotic action and bacterial growth rate. In particular the growth-dependent bacterial susceptibility is controlled by a single, `universal' parameter and the extreme behaviours correspond to the phenomenological classification into bactericidal and bacteriostatic antibiotics. If time allows I will describe how the predictions of the model are backed up by experimental studies.

ONE LOOP CORRECTIONS TO HOLOGRAPHIC WILSON LOOPS

On the field theory side, the vacuum expectation values of Wilson loops in arbitrary representations of SU(N) are captured to all orders in perturbation theory by a Gaussian matrix model. Of prominent interest are the k-symmetric and k-antisymmetric representations, whose gravitational description is given in termsof D3- and D5-branes, respectively, with fluxes in their world volumes. At leading order in N and λ the agreement in both cases is exact. In this talk we explore the structure of the next-to-leading order correction in the matrix model and compare with existing string theory calculations. We also discuss ways to improve the holographic computations to match the sub-leading corrections in the matrix model. -

Submillimeter Astronomy – Molecules and Dust in the Universe

MPIfROrganizer Faculty of PhysicsContact Abstract Show full text abstract about In our Universe, new stars are forming since at least 13 bil...» In our Universe, new stars are forming since at least 13 billion years – and still today – out of dense clouds of interstellar gas and dust. At optical wavelengths, dust absorption prohibits observations of the youngest stars and the process of their formation. In contrast, at 1000-10000 times longer wavelengths, the dust is shining brightly as are molecules from a plethora of different species, some of them quite complex. Since molecules have there rotational spec-tra at millimeter or shorter wavelengths, the submillimeter wavelength (or terahertz frequen-cy) regime offers optimal opportunities for studies of the cradles of stars and many other in-teresting astronomical environments. An inherently interdisciplinary enterprise, frontier sub-millimeter astronomy crucially depends on laboratory spectroscopy and experimentation, state of the art detector development and modern telescope technology working on the driest sites on Earth, in the stratosphere or in space. An overview of this exciting field will be given, illustrated with newest results.

Random matrices and cold fermions in harmonic traps

WISOrganizer Department of Physics of Complex SystemsContact Abstract Show full text abstract about Random matrix theory has found many applications spanning a ...» Random matrix theory has found many applications spanning a vast number of fields in physics and mathematics in the last two decades. Most recently, the equivalence between the statistics of eigenvalues of Gaussian Hermitian matrices and the position of ground-state harmonically confined 1-D fermionic particles has been studied to obtain many interesting and universal results in cold atoms. In my talk, I explore this connection to solve the problem of determining quantum fluctuations of cold fermions using techniques from random matrix theory, expanding previous results that were restricted only to specific scaling limits of the spectrum to yield a full picture of the behavior of fluctuations of fermionic particles in one dimensional traps. -
