Quasistable gradient and hamiltonian systems with a pairwiseinteraction randomly perturbed by wiener processes [PDF]

open access: yesInternational Journal of Stochastic Analysis, 2002
Let \(w_k\) be a sequence of independent standard Wiener processes in \(R^d\), \(x_k\) be a finite or infinite sequence of \(R^d\)-valued stochastic processes that describe the evolution of a set of randomly perturbed pairwise interacting particles. Gradient and Hamiltonian systems of the form \[ dx_k(t)=F_k(t) dt+\sigma dw_k(t) \quad\text{and}\quad d ...

Weak Quasistability and Rajchman measures

open access: yes
It is shown that weak quasistability does not imply power boundedness, but coercive power unbounded operators cannot be weakly quasistable.\ Although a finite measure over the unit disc is a Rajchman measure if and only if the position operator is weakly stable, it is shown that the position operator is weakly quasistable for every finite continuous ...

Quasistates in a ring coupled to a reservoir and their relation to the Dicke effect

open access: yes, 2003
We study the energy spectrum and the persistent current in an ideal one-dimensional mesoscopic ring coupled to an external fermionic reservoir. The contact between ring and reservoir is described by a tunneling operator, which causes an indirect coupling between different ring states via states in the reservoir. For strong coupling to the reservoir new

Continuity argument revisited: geometry of root clustering via symmetric products

open access: yes, 2016
We study the spaces of polynomials stratified into the sets of polynomial with fixed number of roots inside certain semialgebraic region $\Omega$, on its border, and at the complement to its closure.

Mechanisms and Characteristics of Thermodynamically Quasistable Structure Formation in Metals

open access: yesEnvironmental and Climate Technologies
Abstract This paper investigates the processes of thermodynamic pseudostability (metastability) in liquid metals during rapid solidification, a mechanism that results in the formation of an amorphous structure. Established technologies for creating bulk amorphous materials are typically limited to producing only a thin amorphous layer.

Compactified Jacobians as Mumford models

open access: yes, 2019
We show that relative compactified Jacobians of one-parameter smoothings of a nodal curve of genus g, as constructed by Caporaso, Esteves, and Simpson, are Mumford models of the generic fiber.
