We investigate the effects of disorder and shielding on quantum transports in a two dimensional system with all-to-all long range hopping. In the weak disorder, cooperative shielding manifests itself as perfect conducting channels identical to those of the short range model, as if the long range...
摘要: Nonrelativistic quantum-mechanical scattering in two dimensions is discussed. Two approximation methods—partial waves and the Born approximation—are presented with examples.关键词: General or Review, Theoretical or Mathematical/ quantum theory teaching/ nonrelativistic quantum mechanical scattering ...
We study the near-threshold behavior of scattering phase shifts, quantum reflection amplitudes, and quantization functions for systems described by a circularly symmetric potential in two spatial dimensions. In contrast to the three-dimensional case, the centrifugal potential (m(2)-14)h(2)/(2Mr(2...

We discuss the quantum scattering process in the moduli space consisting of two maximally charged dilaton black holes. The black hole moduli space geometry has different structures for arbitrary dimensions and various values of dilaton coupling. We study the quantum effects of the different moduli sp...
In this paper, we model the transport of electrons in a two-dimensional resistor as regions of free propagation with occasional elastic scattering by a random array of scatterers. The overall transmission probability is calculated by cascading the scatter matrices of individual scatterers. Numerical res...
eld theories in higher dimensions. High-energy scattering amplitudes involving ?elds with de?nite helicity in fourdimensional Quantum Chromodynamics have a rather simple description, presumably related to integrable models[32], the same being true for high-energy scattering[33]. In the former case,...

in condensed matter. Traditional optical spectroscopies (e.g., infrared, UV-vis absorption, Raman scattering) offer valuable insights into condensed matter's speciation and structure but fall short in interface sensitivity and selectivity. Sum Frequency Generation (SFG), a second-order nonlinear ...
two dimensions has been an enticing goal for decades. Here we present the quantum simulation of Ising models with two-dimensional ion crystals in a Paul trap. We benchmark the simulator by implementing various spin models with complex interaction networks and adiabatically prepare the corresponding ...
