Hexagonal eutectic solidification patterns operating near a marginal stability point
Mikael Perrut, Silvère Akamatsu, Sabine Bottin-Rousseau +1
We study the long-time dynamics of hexagonal directional-solidification patterns in bulk samples of a transparent eutectic alloy using an optical method which permits real-time obs…
Separability bounds on multiqubit moments due to positivity under partial transpose
A R Usha Devi, A K Rajagopal
Positivity of the density operator reflects itself in terms of sequences of inequalities on observable moments. Uncertainty relations for non-commuting observables form a subset of…
Instability of q-expectation value
Sumiyoshi Abe
q-Expectation value of a physical quantity is widely used in nonextensive statistical mechanics. Here, it is shown that the q-expectation value is not stable under small deformatio…
Macroscopic proof of the Jarzynski-Wojcik fluctuation theorem for heat exchange
Yuki Sughiyama, Sumiyoshi Abe
In a recent work, Jarzynski and Wojcik (2004 Phys. Rev. Lett. 92, 230602) have shown by using the properties of Hamiltonian dynamics and a statistical mechanical consideration that…
