Scientists magnet novel quantum effects
2020/7/31
An international team led by researchers at Princeton University has uncovered a new class of magnet that exhibits novel quantum effects at room temperature. Quantum magnets are promising pl...
Buckled nano rod - a two state system: quantum effects on its dynamics
Buckled nano rod two state system quantum effects dynamics
2011/8/4
Abstract: We consider a suspended elastic rod under longitudinal compression. The compression can be used to adjust potential energy for transverse displacements from harmonic to double well regime. T...
An alternative unified formulation for integer and fractional quantum Hall effects
quantum Hall effect fractional quantum effect degeneracy density Hall quantum number
2011/8/2
Abstract: In this paper, a new unified formulation of integer and fractional quantum Hall effect are presented. Firstly, under the condition of strong magnetic field and symmetry gauge, the Pauli equa...
Effects of Momentum Conservation and Flow on Angular Correlations at RHIC
Effects of Momentum Conservation Flow on Angular Correlations RHIC
2011/1/7
Correlations of azimuthal angles observed at RHIC have gained great attention due to the prospect of identifying uctuations of parity-odd regions in the eld sector of QCD.
Can noncommutative effects of quantum nature account for the present speed up of the cosmic expansion?
noncommutative quantum nature account
2010/12/20
In this paper we investigate to which extent noncommutativity, a intrinsically quantum property,may influence the Friedmann-Robertson-Walker cosmological dynamics at late times/large scales.
Laser phase noise effects on the dynamics of optomechanical resonators
optomechanical resonators laser phase noise Quantum Physics
2010/11/8
We investigate theoretically the influence of laser phase noise on the cooling and heating of a generic cavity optomechanical system. We derive the back-action damping and heating rates and the mechan...
Competing quantum effects in the dynamics of a flexible water model
quantum effects dynamics of a flexible water model
2010/11/18
Numerous studies have identi ed large quantum mechanical e ects in the dynamics of liquid
water. In this paper, we suggest that these e ects may have been overestimated due to the use of rigid water ...
Coupled-channels density-matrix approach to low-energy nuclear collision dynamics: A technique for quantifying quantum decoherence effects on reaction observables
Coupled-channels density-matrix low-energy nuclear collision dynamics reaction observables
2010/11/11
The coupled-channels density-matrix technique for nuclear reaction dynamics, which is based on the Liouville-von Neumann equation with Lindblad dissipative terms, is developed with the inclusion of fu...
A scheme to couple the motion of a single atom with a crystal membrane could enable quantum-mechanical effects to be seen on a larger scale than ever before. The idea, which has been proposed by resea...
Quantum Effects in Water: Proton Kinetic Energy Maxima in Stable and Supercooled Liquid
momentum distribution hydrogen bond supercooled water density maximum
2010/7/5
A strong temperature dependence of proton mean kinetic energy was observed for liquid water around the density maximum and for moderately supercooled water. Line shape analysis of proton momentum dist...
Noise effects in a three-player Prisoner's Dilemma quantum game
Prisoner＇s Dilemma Three-player Decoherenc Correlated Noise Dephasing Channel
2010/4/8
We study the three-player Prisoner's Dilemma game under the effect of decoherence and correlated noise. It is seen that the quantum player is always better off over the classical players. It is also s...
