Forced transport of deformable containers through narrow constrictions [PDF]

Nano Lett. 2012, 12, 4455, 2014
We study, numerically and analytically, the forced transport of deformable containers through a narrow constriction. Our central aim is to quantify the competition between the constriction geometry and the active forcing, regulating whether and at which ...

On transport in quantum Hall systems with constrictions [PDF]

Europhysics Letters, Vol. 80, 17003 (2007)., 2006
Motivated by recent experimental findings, we study transport in a simple phenomenological model of a quantum Hall edge system with a gate-voltage controlled constriction lowering the local filling factor.

A quantum point contact for neutral atoms [PDF]

Physical Review Letters 83 (19), 3762 (1999), 1999
We show that the conductance of neutral atoms through a tightly confining waveguide constriction is quantized in units of lambda_dB^2/pi, where lambda_dB is the de Broglie wavelength of the incident atoms.

Microscopic Theory of Josephson Mesoscopic Constrictions [PDF]

, 1993
We present a microscopic theory for the d.c. Josephson effect in model mesoscopic constrictions. Our method is based on a non-equilibrium Green function formalism which allows for a self-consistent determination of the order parameter profile along the ...

Andreev States in long shallow SNS constrictions [PDF]

, 2001
We study Andreev bound states in a long shallow normal constriction, which is open to a superconductor at both ends. The interesting features of such setup include the absence of electron-hole symmetry and the interference of electron waves along the ...

Transport through constricted quantum Hall edge systems: beyond the quantum point contact [PDF]

Phys. Rev. B 77, 035331 (2008), 2007
Motivated by surprises in recent experimental findings, we study transport in a model of a quantum Hall edge system with a gate-voltage controlled constriction.

Controlling hysteresis in superconducting constrictions with a resistive shunt [PDF]

Fast Track Communications in Supercond. Sci. Technol. 28 (2015) 072003, 2015
We demonstrate control of the thermal hysteresis in superconducting constrictions by adding a resistive shunt. In order to prevent thermal relaxation oscillations, the shunt resistor is placed in close vicinity of the constriction, making the inductive ...

Non-local impact of distal airway constrictions on patterns of inhaled particle deposition. [PDF]

R Soc Open Sci
Airway constriction and blockage in obstructive lung diseases cause ventilation heterogeneity and create barriers to effective drug deposition. Established computational particle-deposition models have not accounted for these impacts of disease. We present a new particle-deposition model that calculates ventilation based on the resistance of each ...
