We study macroscopic aspects of crystal surface relaxation in 2+1 dimensions by accounting for nearequilibrium kinetics of transparent steps at the nanoscale. For slowly varying step geometries, we sh...
ELECTROMIGRATION IN MACROSCOPIC RELAXATION OF STEPPED SURFACES

2015/10/16
We study the effect of an external electric field E on macroscopic relaxation laws for crystal surfaces in 2 + 1 dimensions. We derive a nonlinear, fourth-order partial differential equation (PDE) for...
Macroscopic Electromagnetic Response of Arbitrarily Shaped Spatially Dispersive Bodies formed by Metallic Wires
Macroscopic Electromagnetic Response Arbitrarily Shaped Spatially Dispersive Bodies Metallic Wires Computational Physics

In media with strong spatial dispersion the electric displacement vector and the electric field are typically linked by a partial differential equation in the bulk region. The objective of this work i...
Students' Views of Macroscopic and Microscopic Energy in Physics and Biology

2011/9/7
Energy concepts are fundamental across the sciences, yet these concepts can be fragmented along disciplinary boundaries, rather than integrated into a coherent whole. To teach physics effectively to b...
Frictional damping in radiative electrodynamics and its scaling to macroscopic systems
Abraham-Lorentz-Dirac equation, radiation force, Unruh radiation,frictional dissipation
2011/8/30
Radiation force in Abraham-Lorentz-Dirac equation is revisited for possible signature of irreversible action in the dynamics. The analysis shows that the classical electron can ‘dissipate’ out a certa...
Macroscopic time evolution and MaxEnt inference for closed systems with Hamiltonian dynamics
MaxEnt algorithm information theory statistical mechanics Hamiltonian dynamics
2010/11/24
MaxEnt inference algorithm from the information theory is relevant for the time evolution of macroscopic systems which represents a problem of incomplete information. Two different approaches using Ma...
Quantum Bell Inequalities from Macroscopic Locality
Macroscopic Locality Bell Inequalities Quantum Physics
2010/11/8
We propose a method to generate analytical quantum Bell inequalities based on the principle of Macroscopic Locality. By imposing locality over binary processings of virtual macroscopic intensities, we...
van't Hoff-Arrhenius Analysis of Mesoscopic and Macroscopic Dynamics of Simple Biochemical Systems: Stochastic vs. Nonlinear Bistabilities
van't Hoff-Arrhenius Analysis Mesoscopic Macroscopic Dynamics
2010/11/16
Multistability of mesoscopic, driven biochemical reaction systems has implications to a wide range of cellular processes. Using several simple models, we show that one class of bistable chemical syste...

We have carried out systematic Macroscopic Quantum Tunneling (MQT) experiments on Nb/Al-
AlOx/Nb Josephson junctions (JJs) of different areas. Employing on-chip lumped element inductors,we have decou...

This article reports on the long-term frequency stabilty characterisation of a new type of cryogenic sapphire oscillator using an autonomous pulse-tube cryocooler as its cold source. This new design e...
Macroscopic quantum tunneling in multigap superconducting Josephson junctions: Escape rate enhancement via quantum fluctuations of Josephson-Leggett mode
Macroscopic quantum superconducting Josephson Escape rate enhancement Josephson-Leggett mode
2010/11/5
We theoretically study the macroscopic quantum tunneling (MQT) in a hetero Josephson junction formed by a conventional single-gap superconductor and a multi-gap one such as ${MgB}_{2}$ and iron-based...
We show that for macroscopic measurements which cannot reveal full information about microscopic states of the system, the monogamy of Bell inequality violations present in quantum mechanics implies t...
A perspectival version of the modal interpretation of quantum mechanics and the origin of macroscopic behavior
modal interpretation relational properties, measurement realism
2011/9/7
We study the process of observation (measurement), within the framework of a `perspectival' (`relational', `relative state')version of the modal interpretation of quantum mechanics. We show that if we...
A perspectival version of the modal interpretation of quantum mechanics and the origin of macroscopic behavior
Quantum mechanics modal interpretations relational properties relativity Lorentz invariance
2011/9/7
Recent no go theorems by Dickson and Clifton (1998), Arntzenius (1998) and Myrvold (2002) demonstrate that current modal interpretations are incompatible with relativity. In this paper we propose stra...
Temporal Leggett-Garg-Bell inequalities for sequential multi-time actions in quantum information processing, and a re-definition of Macroscopic Realism
Temporal Leggett-Garg-Bell inequalities sequential multi-time actions quantum information processing a re-definition Macroscopic Realism
2010/10/19
The usual formulation of Macrorealism is recast to make this notion fully concurrent with the basic ideas behind classical physics. The assumption of non-invasiveness of measurements is dropped. Inste...
