چکیده
Quantum tunneling of magnetization and quantum phase interference have been intensively studied in single molecule magnets (SMMs), high spin molecules with an easy axis (Ising) type magnetic anisotropy. SMMs have also been proposed as candidate qubits—and very recently several groups have reported the observation of coherent spin dynamics in pulsed EPR studies. In the first part of this talk I will review experiments and theory of SMMs, including the spin-Hamiltonians that capture the physics of their spin-dynamics. I will then discuss recent experiments in my group on spin-relaxation between low-lying spin-states in Ni4, an S=4 SMM [1, 2].

What Really Matters: Living Longer or Living Healthier; Comment on “Shanghai Rising: Health Improvements as Measured by Avoidable Mortality Since 2000”
The decline in Avoidable Mortality (AM) and increase in life expectancy in Shanghai is impressive. Gusmano and colleagues suggested that Shanghai’s improved health system has contributed significantly to this decline in AM. However, when compared to other global cities, Shanghai’s life expectancy at birth is improving as London and New York City, but has yet to surpass that of Hong Kong, Tokyo,...
