    Sum rule for the optical absorption of an interacting many-polaron gas

    A sum rule for the first frequency moment of the optical absorption of a many-polaron system is derived, taking into account many-body effects in the system of constituent charge carriers of the many-polaron s...

    Wigner lattice of ripplopolarons in a multielectron bubble in helium

    The properties of ripplonic polarons in a multielectron bubble in liquid helium are investigated on the basis of a path-integral variational method. We find that the two-dimensional electron gas can form deep ...

    Dynamical exchange effects in a two-dimensional many-polaron gas

    We calculate the influence of dynamical exchange effects on the response properties and the static properties of a two-dimensional many-polaron gas. These effects are not manifested in the random-phase approxi...

    Magnetohydrodynamic properties of incompressible Meissner fluids

    We consider a superconducting material that exists in the liquid state, more precisely, in which the Meissner-Ochsenfeld effect persists in the liquid state. First, we investigate how the shape of such a hypot...

    Generalized pricing formulas for stochastic volatility jump diffusion models applied to the exponential Vasicek model

    Path integral techniques for the pricing of financial options are mostly based on models that can be recast in terms of a Fokker-Planck differential equation and that, consequently, neglect jumps and only desc...
