PT-symmetric quantum mechanics,   The average quantum physicist on the street would say that a quantum-mechanical Hamiltonian must be Dirac Hermitian (invariant under combined matrix transposition and complex conjugation) in order to guarantee that the energy eigenvalues are real and that time evolution is unitary. However, the Hamiltonian $H=p^2+ix^3$, for example, which is obviously not Dirac Hermitian, has a positive real discrete spectrum, generates unitary time evolution, and thus defines a fully consistent and physical quantum theory. Evidently, the axiom of Dirac Hermiticity is too restrictive. While $H=p^2+ix^3$ is not Dirac Hermitian, it is PT symmetric (invariant under combined space reflection P an time reversal T). The quantum mechanics defined by a PT-symmetric Hamiltonian is a complex generalization of ordinary quantum mechanics. When quantum mechanics is extended into the complex domain, new kinds of theories having strange and remarkable properties emerge. Some of these properties have been… University Event Topic: Academics. Research. Science. School: Emory College. Department / Organization: Physics Department.

Title: Building the cell from unreliable parts: coordinating stochastic organelle biogenesis with cellular growth,   Abstract: Perhaps the defining feature of the eukaryotic cell is its organization into membrane-bound compartments known as organelles. While the processes underlying the biogenesis of individual organelles are often well-known, the precision with which individual cells exert quantitative control over individual organelle properties, such as number and size, and coordinate these properties at systems-scale across the cell’s many different types of organelles remain frontier problems in cell biology and biophysics. Using a combination of theory and quantitative fluorescence imaging, I will describe our recent efforts to show that cells exhibit substantial limits to the precision with which they can control organelle numbers and sizes, but despite this appear to collectively organize organelle biogenesis into specific “modes” to achieve homeostasis in cell size and growth rate.
