A Time-Dependent Theory of Quantum Resonances

The Quantum Statistical Mechanical Theory of Transport Processes

A new derivation of the quantum Boltzmann transport equation for the Fermion system from the quantum time evolution equation for the wigner distribution function is presented. The method exhibits the origin of the time - irreversibility of the Boltzmann equation. In the present work, the spin dependent and indistinguishibility of particles are also considered.

Resonances in n-body quantum systems with dilatation analytic potentials and the foundations of time-dependent perturbation theory*

اتلاف در مدارهای الکتریکی کوانتومی مزوسکوپی RLC

The quantum theory for a mesoscopic electric circuit with charge discreteness is investigated. Taking the Caldirola-Kanai Hamiltonian in studding quantum mechanics of dissipative systems, we obtain the persistent current and the energy spectrum of a damped quantum LC-design mesoscopic circuit under the influence of a time-dependent external field.

Is a Quantum Theory of Resonances Really Time Asymmetric?

The title “Time Asymmetric Quantum Theory: the Theory of Resonances” (without questionmark) of the CFIF workshop (23.–26.7.2003, Lisbon, Portugal) implies that the theoretical description of resonances is uniquely described by the formalism of A. Bohm et al. [1, 2] reflecting the title of the workshop. Our presentation in this workshop tries to introduce an apparently inequivalent, alternative ...

Time-dependent analysis of carrier density and potential energy in spherical centered defect InGaAs/AlGaAs quantum dot (SCDQD)

Interaction and correlation effects in quantum dots play a fundamental role in defining both their equilibrium and transport properties. Numerical methods are commonly employed to study such systems. In this paper we investigate the numerical calculation of quantum transport of electrons in spherical centered defect InGaAs/AlGaAs quantum dot (SCDQD). The simulation is based on the imaginary time...
