Making use of a generalized Green’s function technique and Landauer formalism, the temperature depended current-voltage (I-V) characteristics of C60 molecule, sandwiched between two metallic electrodes are numerically investigated. In addition, the influence of the electron-phonon coupling strength on the electronic properties of the molecule is studied. The I-V characteristics of the molecule ...

‖ In connection with the preceding article by Otto Meyerhof, a few words on Nelson’s significance for the philosophy of mathematics might be added. Nelson was among those philosophers whose style of thinking resulted from a familiarity with the spirit of the exact sciences. Mathematics and physics represented the methodical ideal that he strove to achieve in elaborating his philosophical though...

It has been shown that the temperature of the oesophagus in the anaesthetized and intubated adult is not uniform along its length. There is an area below the distal end of the endotracheal tube that is affected by ventilation and the temperature of the inspired gases. This area does not extend into the lowest quarter of the oesophagus (Stupfel and Severinghaus, 1956; Whitby and Dunkin, 1963, 19...

Matrix model describing the anomalous dimensions of composite operators in N = 4 super Yang–Mills theory up to one-loop level is considered at finite temperature. We compute the thermal effective action for this model, which we define as the log of the partition function restricted to the states of given fixed length and spin. The result is obtained in the limits of high and low temperature.

In this work, we exploit an efficient algorithm for the sampling of hydrogen-bond networks in order to study the order/disorder transition and the dielectric properties of ice Ih. Our results show that all of the rigid point charge models studied, TIP4P/Ice, TIP4P/2005, TIP4P, and SPC/E, yield a very low dielectric constant as compared with experiment. The analysis of the polarization factor, G...

We investigate the low energy properties of Lorentz-invariant theories with a spontaneously broken rotation symmetry O(N) → O(N–1). The leading coefficients of the low temperature expansion for the partition function are calculated up to and including three loops. Emphasis is put into the special case N=3: it describes the antiferromagnet which has been extensively studied. Our results obtained...

We theoretically analyze a single vortex in a spin polarized 3D trapped atomic Fermi gas near a broad Feshbach resonance. Above a critical polarization the Andreev-like bound states inside the core become occupied by the majority spin component. As a result, the local density difference at the core center suddenly rises at low temperatures. This provides a way to visualize the lowest bound stat...

A non-linear Penner type interaction is introduced and studied in the random matrix model of homo-RNA. The asymptotics in length of the partition function is discussed for small and large N (size of matrix). The interaction doubles the coupling (v) between the bases and the dependence of the combinatoric factor on (v,N) is found. For small N , the effect of interaction changes the power law exp...
