Semiclassical theory of energy diffusive escape in a Duffing oscillator
Semiclassical theory energy diffusive escape Duffing oscillator
2010/10/27
Motivated by recent experimental progress to read out quantum bits implemented in superconducting circuits via the phenomenon of dynamical bifurcation, transitions between steady orbits in a driven an...
Bang-Bang Control Design for Quantum State Transfer based on Hyperspherical Coordinates and Optimal Time-energy Control
Bang-Bang Control Design Quantum State Transfer Hyperspherical Coordinates Optimal Time-energy Control
2010/10/21
We present a constructive control scheme for solving quantum state engineering problems based on a parametrization of the state vector in terms of complex hyperspherical coordinates. Unlike many contr...
We introduce the "total s-energy" of a multiagent system and bound its maximum asymptotic value. This offers a new analytical lens on bidirectional agreement dynamics. We use our results to bound the ...
Equipartition of energy and the first law of thermodynamics at the apparent horizon
thermodynamics Equipartition of energy apparent horizon
2010/3/18
We apply the holographic principle and the equipartition law of energy to the apparent horizon
of a Friedmann-Robertson-Walker universe and derive the Friedmann equation describing the dy-
namics of...
Azimuthal asymmetries in production of charged hadrons by high energy muons on polarized deuterium targets
Azimuthal asymmetries polarized deuterium targets high energy muons
2010/3/15
Search for azimuthal asymmetries in semi-inclusive production of charged hadrons by 160 GeV muons on the longitudinally polarized deuterium target, has been performed using the 2002- 2004 COMPASS data...
Energy-Entanglement Relation for Quantum Energy Teleportation
Energy-Entanglement Quantum Energy Teleportation
2010/3/10
Protocols of quantum energy teleportation (QET), while retaining causality and local energy conservation, enable the transportation of energy from a subsystem of a many-body quantum system to a distan...
Wormholes respecting energy conditions and solitonic shells in DGP gravity
Wormholes solitonic shells energy conditions
2010/3/18
We build spherically symmetric wormholes within the DGP theory. We calculate the energy localized on the shell, and we find that for certain values of the parameters wormholes could be supported by ma...
A Novel Scheme to Search for Fractional Charge Particles in Low Energy Accelerator Experiments
Fractional Charge Particles Low Energy Accelerator Experiments
2010/3/15
In the Standard Model of particle physics, the quarks have fractional charge equal to $\pm1/3$ or $\pm2/3$ of the electron's charge. There have been a large number of experiments in searching for frac...
Low-energy muons via frictional cooling
Frictional Cooling Low-energy muon Muon beam Geant4
2010/3/15
Low-energy muon beams are useful for a range of physics experiments. We consider the production of low-energy muon beams with small energy spreads using frictional cooling. As the input beam, we take ...
Reporter’s Notebook: How to spur energy storage innovations（图）
Reporter’s Notebook energy storage innovations
2009/12/22
Imagine flying all the way from coast to coast, completely guilt-free, in an airplane that doesn’t emit a single particle of greenhouse gas or air pollutants. That could happen someday, perhaps brough...
