High-precision measurement of the thermal exponent for the three-dimensional XY universality class
Accuracy of measurement measurement superfluids lipase
2014/12/20
Simulation results are reported for the critical point of the two-component ϕ4 field theory. The correlation-length exponent is measured to high precision with the result ν=0.6717(3). This value ...
Very High Precision Determination of Low-Energy Parameters: The 2-d Heisenberg Quantum Antiferromagnet as a Test Case
Very High Precision Determination of Low-Energy Paraameters 2-d Heisenberg Quantum Antiferromagnet Test Case
2011/1/14
The 2-d spin 1 2 Heisenberg antiferromagnet with exchange coupling J is investigated on a periodic square lattice of spacing a at very small temperatures using the loop-cluster algorithm. Monte Carlo ...
Precision Measurement of CP Violation in D0->pi+pi- at CDF
Precision Measurement CP Violation D0->pi+pi- at CDF
2011/1/4
We report a preliminary measurement of the CP violating asymmetry in D0 →p+p− using approximately 215·000 decays reconstructed in about 5.94 fb−1 of CDF data.
Effective Field Theory and High-Precision Calculations of Nuclear Electroweak Processes
Effective Field Theory High-Precision Calculations of Nuclear Electroweak Processes
2011/1/7
High-precision calculations of electroweak processes in light nuclei are of great importance
for multiple reasons. Gerry Brown together with Dan-Olof Riska published in 1972 a famous calculation on r...
Proposal of a two-qutrit contextuality test free of the finite precision and compatibility loopholes
two-qutrit contextuality finite precision compatibility loopholes
2010/10/19
It has been argued that any test of quantum contextuality is nullified by the fact that perfect
orthogonality and perfect compatibility cannot be achieved in finite precision experiments. We in-trodu...
