چکیده
We present compelling empirical evidence for a new interpretation of the Forward Rate Curve (frc) term structure. We find that the average frc follows a squareroot law, with a prefactor related to the spot volatility, suggesting a Value-at-Risk like pricing. We find a striking correlation between the instantaneous frc and the past spot trend over a certain time horizon. This confirms the idea of an anticipated trend mechanism proposed earlier and provides a natural explanation for the observed shape of the frc volatility. We find that the one-factor Gaussian Heath-Jarrow-Morton model calibrated to the empirical volatility function fails to adequately describe these features.

We demonstrate a variant of the Bond Fluctuation lattice Monte Carlo model which conserves a topological linking number by forbidding moves through cis conformations. Unlike previous models that conserve linking number, our simulated ring chains have flexibility and the scaling properties of a lattice self-avoiding walk. Increased linking number reduces the radius of gyration mildly. A linking ...

The Josephson quasiparticle (JQP) cycle in a voltage-biased superconducting single-electron transistor (SSET) combines coherent Cooper pair tunneling with incoherent quasiparticle decay. We have measured the influence of current flow through an independently-biased SSET on the JQP cycle when the two SSET’s have a strong mutual capacitive coupling. We find, among other effects, that the JQP curr...

In this work, we consider the issue of pricing exchange options and spread options with stochastic interest rates. We provide the closed form solution for the exchange option price when interest rate is stochastic. Our result holds when interest rate is modeled with a stochastic term structure of general form, which includes Vasicek model, CIR term structure, and other well-known term structure...

It is shown that the binding effect that is associated with the short range part of the Goldstone boson exchange interaction between constituent quarks provides a good description of the πN σ-term.
