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…
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…
Seismic Negative Belt of Acoustic Metamaterials
Sang-Hoon Kim, Mukunda P. Das
An earthquake-proof seismic negative belt of an artificial seismic shadow zone is introduced. The belt is composed of acoustic materials which has one of the constituent parameter…
Acoustic Eaton lens array and its fluid application
Sang-Hoon Kim, Sy Pham-Van, Mukunda P. Das
A principle of an acoustic Eaton Lens array and its application as a removable tsunami wall is proposed theoretically. The lenses are made of expandable rubber pillars or balloons…
Revisiting the Fermi Surface in Density Functional Theory
Mukunda P. Das, Frederick Green
The Fermi surface is an abstract object in the reciprocal space of a crystal lattice, enclosing the set of all those electronic band states that are filled according to the Pauli p…
