Conservation in High-field Quantum Transport
Mukunda P. Das, Frederick Green
We give a short overview of the role of microscopic conservation in charge transport at small scales, and at driving fields beyond the linear-response limit. As a practical example…
Hamiltonian perspective on parquet theory
Frederick Green, Thomas L. Ainsworth
Understanding collective phenomena calls for tractable descriptions of correlations in assemblies of strongly interacting constituents. Capturing the essence of their self-consiste…
On Three "Anomalous" Measurements of Nonlinear QPC Conductance
Mukunda P. Das, Frederick Green
Practical mesoscopic devices based on quantum point contacts (QPCs) must function at operating point involving large internal driving fields. Experimental evidence has accumulated…
Stochastic Hamiltonians for correlated electron models
Frederick Green
Microscopically conserving reduced models of many-body systems have a long, highly successful history. Established theories of this type are the random-phase approximation for Coul…
Anomalous Conductance Quantization in the Inter-band Gap of a One-dimensional Channel
Frederick Green, Mukunda P. Das
We report on a striking departure from the canonical step sequence of quantized conductance in a ballistic, quasi-one-dimensional metallic channel. Ideally, in such a structure, ea…
Conductance Anomalies in Quantum Point Contacts and One Dimensional Wires
Mukunda P. Das, Frederick Green
Over the last decade, interest in one-dimensional charge transport has progressed from the seminal discovery of Landauer quantization of conductance, as a function of carrier densi…
