An introduction to topological phases of electrons
... If you wonder why the prefix “co-” appears in “cohomology”, there is a dual theory of linear combinations of curves, etc., called homology, in which the differential operator in de Rham cohomology is replaced by the boundary operator. However, while arguably more basic mathematically, homology seems ...

... We’ll start by considering an isolated system with fixed energy, E. For the purposes of the discussion we will describe our system using the language of quantum mechanics, although we should keep in mind that nearly everything applies equally well to classical systems. In your first two courses on ...

... In quantum simulation, we are interested in the behavior and properties of a quantum system, which could be either a stationary molecule or a chemical reaction. The procedure of quantum simulation can be summarized in three steps: (a) preparing the quantum state into an initial state, (b) evolving t ...

One-phonon relaxation of localized electronic states in anharmonic nanoparticles
...

This follows directly from the perturbati ...

Noise and Decoherence in Quantum Two-Level Systems
... To get further insight into dephasing phenomena we analyze some experimental scenarios. In particular, we discuss their sensitivity to details of the preparation of the initial state (cf., e.g., Ref. [8]). Such a preparation is a necessary ingredient in an experiment probing dephasing processes dire ...
