Anderson Localization
From the start of their studies students in condensed matter physics are exposed to ordered systems. These systems can be very simple and give insight into the physics of many materials. However it seems that much of what is learned in ordered systems cannot be brought to disordered systems. Instead new conceptual understandings much be reached will very different consquences. One of these is t...
متن کاملAnderson Localization in Atoms
We investigate the celebrated analogy [1] between Anderson localization phenomena in condensed matter physics [2] and related effects in the ionization process of driven Rydberg atoms, and put them on a quantitative footing. The atomic system we consider for a comprehensive numerical analysis of its ionization properties is a highly excited hydrogen atom exposed to a monochromatic electromagnet...
متن کاملLocalization for an Anderson-Bernoulli model with generic interaction potential
We present a result of localization for a matrix-valued AndersonBernoulli operator, acting on L2(R) ⊗ R , for an arbitrary N ≥ 1, whose interaction potential is generic in the real symmetric matrices. For such a generic real symmetric matrix, we construct an explicit interval of energies on which we prove localization, in both spectral and dynamical senses, away from a finite set of critical en...
متن کاملEnhanced optical Anderson localization effects in modulated Bloch lattices
We study Anderson localization dynamics in periodically modulated optical Bloch arrays. Using an effective model, we show that, in such arrangements, even a weak disorder may play an important role and can lead to enhanced Anderson localization effects. Copyright c © EPLA, 2012 Introduction. – Anderson localization (AL) is an important quantum-mechanical process that describes the absence of di...
متن کاملAnderson localization in carbon nanotubes: defect density and temperature effects.
The role of irradiation induced defects and temperature in the conducting properties of single-walled (10, 10) carbon nanotubes has been analyzed by means of a first-principles approach. We find that divacancies modify strongly the energy dependence of the differential conductance, reducing also the number of contributing channels from two (ideal) to one. A small number of divacancies (5-9) bri...
