Watching the Hoyle State Fall Apart
W e are used to picturing atomic nuclei as smooth and spherical distributions of neutrons and protons. But the reality is often very different, and the carbon-12 nucleus provides the perfect case in point. In its ground state and some of its excited states, carbon’s six neutrons and six protons are thought to segregate into three clusters of two neutrons and two protons, otherwise known as heli...
متن کاملContracts and externalities: How things fall apart
A single principal interacts with several agents, offering them contracts. The crucial assumption of this paper is that the outside-option payoffs of the agents depend positively on how many “free agents” there are (these are agents who are not under contract). We study how such a principal, unwelcome though he may be, approaches the problem of contract provision to agents when coordination fai...
متن کاملThings Fall Apart : The ‘ End Game ’ Dynamics of Internal Wars
Most internal wars end on the battlefield. In comparison to inter-state conflicts, a relatively small percentage of these fights are concluded at the negotiating table. While significant attention has been given to how and why internal wars begin and even how they begin to evolve, little attention has been given to how they are concluded. What research has been done on this subject has focused ...
متن کاملThings Fall Apart: Topology Change from Winding Tachyons
We argue that closed string tachyons drive two spacetime topology changing transitions – loss of genus in a Riemann surface and separation of a Riemann surface into two components. The tachyons of interest are localized versions of Scherk-Schwarz winding string tachyons arising on Riemann surfaces in regions of moduli space where string-scale tubes develop. Spacetime and world-sheet renormaliza...
متن کاملCSE 599d - Quantum Computing When Quantum Computers Fall Apart
In this lecture we are going to begin discussing what happens to quantum computers when we move away from the closed system view of quantum theory and encounter the reality that real quantum system are open quantum systems. Open quantum systems interact with their environment and decohere. When we try to control real quantum systems, we aren’t able to perfectly control them. When we try to perf...
