, 2004 We give here the derivation of a Gross-Pitaevskii--type equation for inhomogeneous condensed bosons. Instead of the original Gross-Pitaevskii differential equation, we obtain an integral equation that implies less restrictive assumptions than are made in

An Abstract Nonlinear Temporally Inhomogeneous Equation
Demonstratio Mathematica, 1990 One considers the abstract semi-linear initial value problem (1) \(du/dt=A(t)u+f(t,u)\), \(t\in[0,T]\), \(u(0)=u_ 0\), where \(X\) is a real reflexive Banach space and, for any \(t\in[0,T]\), \(A(t): X\to X\) a closed densely defined linear operator, \(f: \mathbb{R}\times X\to X\) a nonlinear function and \(u_ 0\in X\).

Advanced Functional Materials, EarlyView.Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

An equation for the limit state of a superconductor with pinning sites
Electronic Journal of Differential Equations, 2005 We study the limit state of the inhomogeneous Ginzburg-Landau model as the Ginzburg-Landau parameter $kappa=1/epsilono infty$, and derive an equation to describe the limit state.

Diffusion equations in inhomogeneous solid having arbitrary gradient concentration
Condensed Matter Physics, 2017 A quantum kinetic equation is obtained for an inhomogeneous solid having arbitrary gradient concentration and chemical potential. We find, starting from nonequilibrium statistical operator, a new equation to describe atom migration in solid states.

Paraxial spin transport using the Dirac-like paraxial wave equation
, 2010 In weakly inhomogeneous media, Maxwell equations assume a Dirac-like form that is particularly apt for the study of paraxial propagation. Using this form, and via the Foldy-Wouthuysen transformation technique of the Dirac equation, we study the spin ...

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance
Advanced Functional Materials, EarlyView.Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

A Constraint on the Anomalous Green's Function
, 1996 It is shown that the physical constraint of the Anomalous Green's function gives a natural pairing condition. The resulting self-consistency equation is directly related to the BCS gap equation.
