Comment on “quantum theory for mesoscopic electric circuits” cond-mat/9907171 and cond-mat/9606206

چکیده
In references con-mat/9907171 and cond-mat/9606206 (Phys.Rev.B 53, 4927 (1996)) by You-Quan Li and Bin Chen, was considered a mesoscopic LC circuit with charge discreteness. So, it was proposed a finite difference Schrödinger equation for the charge time behavior. In this comment, we generalize the corresponding mesoscopic Hamiltonian in order to taken into account the dissipative effects (resistance R). Namely, a quantum term R dt , proportional to the current, is added to the mesoscopic LC circuit equation. This is carried-out in analogy with the theory of Caldirola-Kanai for quantum one particle damping.

Diffusion Poles and the Anderson Transition
In the recent series of papers (cond-mat/0402471, cond-mat/0403618, condmat/0407618, cond-mat/0501586), Janis and Kolorenc discussed the role of the diffision poles in the Anderson transition theory. Their picture contradicts the general principles and is shown below to be completely misleading. Correct setting of the problem is given and the contemporary situation is discussed. The critical re...
متن کاملComment on “ Spurious fixed points in frustrated magnets , ” cond - mat / 0609285
We critically discuss the arguments reported in cond-mat/0609285 by B. Delamotte, Yu. Holovatch, D. Ivaneyko, D. Mouhanna, and M. Tissier. We show that their conclusions are not theoretically founded. They are contradicted by theoretical arguments and numerical results. On the contrary, perturbative field theory provides a robust evidence for the existence of chiral fixed points in O(2) ⊗ O(N) ...
متن کاملReply to Comment by Alexandrov and Bratkovsky [cond-mat/0603467, cond-mat/0606366]
The submitted Comment is based on using an isolated quantum dot approach to discuss the situation where the coupling to the leads is considerable (not negligible). This finite lead coupling is the situation in most molecular transport junctions. In such situations the population on the molecule is not static and dynamical effects (fluctuations) are crucial. While the discussion in Ref. 2, and i...

متن کاملM ar 1 99 7 From Effective BCS Action to Vortex Dynamics
The topological term in the effective action for the electrically neutral BCS system is discussed. It is applied for the calculation of the transverse force acting on the vortex in the limit of the smooth vor-tex core and vanishing interlevel distance in the vortex core. The controversy between the topological terms in cond-mat/9703124 and cond-mat/9411047 is resolved.
