Seth Shostak - SETI: Any Closer to a Discovery?

Are we alone in the universe? The scientific hunt for extraterrestrial intelligence is now well into its fifth decade, and we still haven’t discovered any cosmic company. Could all this mean…

Arch and scaffold: Hilbert space and transformation theory - Michel Janssen

In early 1927, Paul Dirac and Pascual Jordan, independently of one another, published their versions of a general formalism tying the various forms of the new quantum theory together and giving the…

Ion Hydration and Effective Charge - Phil Pincus

Ions in water are typically understood to be hydrated, i.e. the appropriate water dipolar orientations point toward the charge (which is here taken to be of spherical symmetry). Depending on the…

Many-body Entanglement and Tensor Networks - Glen Evenbly

Quantum many-body systems are difficult to study because the space of possible many-body states is huge: its dimension grows exponentially in the system size. However, in recent years progress in our…

Local temperature Ansatz: A novel quantum entanglement based approach for solving strongly correlated systems - Abolhassan Vaezi

The exact solution to interacting quantum problems is, in general, an exponentially hard task due to the exponential growth of the Hilbert space with the system size. As a result, despite extensive…

Course Reform MIT Style: Student Evaluations vs. Scientific Evidence - David E. Pritchard

The evaluation of most course reforms typically rests heavily on teacher and student evaluations; I’ll argue that this is unwise. In contrast, I’ll discuss course reform MIT style: select…
