The kinematical constraints on field theories in two space-time dimensions lead to many unusual effects which have no analogue in higher dimensions. Perhaps the strangest of these is the equivalence between large classes of Bose and Fermi field theories. This correspondence, which has been dubbed bosonization, provides a transparent unified method for solving two dimensional Fermi theories [ l*...

Even-even A'110 nuclei approaching the astrophysical r-process path have been investigated using both the cranked and the configuration-constrained shell models. The calculations show that, with increasing neutron number in the Z>40 nuclides, nuclear shapes evolve from prolate, through triaxial to oblate deformations. In contrast to other regions of the nuclear chart, pronounced oblate shapes d...

Electron transport through short, phase-coherent metal–graphene–metal devices occurs via resonant transmission through particle-in-a-box-like states defined by the atomically-sharp metal leads. We study the spectrum of particle-in-a-box states for singleand bi-layer graphene, corresponding to massless and massive two-dimensional (2-D) fermions. The density of states D as a function of particle ...

Experimental results obtained at the Relativistic Heavy Ion Collider (RHIC) have been interpreted in terms of a strongly interacting quark gluon plasma. The strongly interacting plasma is characterized by “perfect fluidity”, i.e. a ratio of shear viscosity to entropy density that saturates a proposed lower bound. In this contribution we explore the possibility that a similar phenomenon takes pl...

The electronic and structural properties for TiNi, TiPd, and TiPt are studied using first-principles total energy calculations. For each alloy, the structural parameters for a few structural phases are found from energy and force calculations. In each case, we found that the ground state martensitic phase (B19/B198) is indeed lower in energy than the high temperature B2 phase. In all three allo...

Landau-Fermi liquid theory is a powerful effective theory for strongly interacting Fermi systems at low temperatures. It has been successfully applied to liquid He, nuclear matter and nuclei. However, in contrast to the interaction between He atoms, nuclear forces are complicated due to the large non-central spin-orbit and tensor components. Here, we report on the in-medium modification of the ...

Using operator algebraic methods we show that the moment generating function of charge transport in a system with infinitely many non-interacting Fermions is given by a determinant of a certain operator in the one-particle Hilbert space. The formula is equivalent to a formula of Levitov and Lesovik in the finite dimensional case and may be viewed as its regularized form in general. Our result e...

The physics of cold atoms approaches nowadays the frontiers of modern condensed matter physics. In particular many important challenges of this disciplin can be addressed within the context of cold atoms [1]. In this talk, I shall present first a brief review of some of these challenges. I will focus then on those that could be addressed by using Bose-Fermi mixtures in the presence of disorder....
