Comparisons between Membrane, Bridge and Cantilever Miniaturized Resistive Vacuum Gauges

open access: yesSensors, 2012
Using bulk micromachining, meander-shaped resistor elements consisting of 20 nm Cr and 200 nm Au were fabricated on 1 µm thick silicon nitride membranes, bridges, and cantilevers.

Effective field theories for topological insulators by functional bosonization

open access: yes, 2013
Effective field theories that describes the dynamics of a conserved U(1) current in terms of "hydrodynamic" degrees of freedom of topological phases in condensed matter are discussed in general dimension $D=d+1$ using the functional bosonization ...

Simulation and Detection of Photonic Chern Insulators in One-Dimensional Circuit Quantum Electrodynamics Lattice

open access: yes, 2015
We introduce a simple method to realize and detect photonic topological Chern insulators with one-dimensional circiut quantum electrodynamics arrays. By periodically modulating the couplings of the array, we show that this one-dimensional model can be ...

Filling-Enforced Quantum Band Insulators in Spin-Orbit Coupled Crystals

open access: yes, 2016
While band insulators are usually described in wavevector space in terms of fully filled bands, they are sometimes also described in terms of a complementary Wannier picture in which electrons occupy localized, atom-like orbitals.

Experimental work: the effect of using agricultural pond insulators in the core of earthen dams on water flow and dissolved solids content [PDF]

open access: yesArchives of Civil Engineering
Gypsies soils are frequently found in semiarid and arid environments where rainfall does not sufficiently let the gypsum to leach from the soil cover. The efficiency of dams that impound water is reduced by a number of factors, including the breakdown of

Chiral Anomaly, Topological Field Theory, and Novel States of Matter

open access: yes, 2018
Starting with a description of the motivation underlying the analysis presented in this paper and a brief survey of the chiral anomaly, I proceed to review some basic elements of the theory of the quantum Hall effect in 2D incompressible electron gases ...

ON THE NEED TO INCREASE THE RELIABILITY OF LINEAR INSULATORS FOR DISTRIBUTION NETWORKS 10-20 KV

open access: yesElectrical engineering & Electromechanics, 2018
Introduction. In Ukraine high voltage overhead distribution lines (OL) of class 6 and 10 kV are the most extended. Their total length exceeds 280,000 km. More than 95% of the lines are made on line supports from reinforced concrete racks. On all poles of
