Recent work provides a general two-step solution to trap** and cooling of atoms. The first
step is magnetic stop** of paramagnetic atoms with the use of a sequence of pulsed …

Atomtronics focuses on atom analogs of electronic materials, devices, and circuits. A
strongly interacting ultracold Bose gas in a lattice potential is analogous to electrons in solid …

We illustrate that open quantum systems composed of neutral, ultracold atoms in one-
dimensional optical lattices can exhibit behavior analogous to semiconductor electronic …

We experimentally realize a Maxwell's demon that converts information gained by
measurements to work. Our setup is composed of a colloidal particle in a channel filled with …

A minimal model of a quantum refrigerator, ie, a periodically phase-flipped two-level system
permanently coupled to a finite-capacity bath (cold bath) and an infinite heat dump (hot …

We generalize the second law of thermodynamics in its maximum work formulation for a
nonequilibrium initial distribution. It is found that in an isothermal process, the Boltzmann …

This paper extends the work of a previous paper (Ellis, 2013) on the flow of time, to consider
the origin of the arrow of time. It proposes that a 'past condition'cascades down from …

We report the cooling of an atomic ensemble with light, where each atom scatters only a
single photon on average. This is a general method that does not require a cycling transition …

We demonstrate an asymmetric optical potential barrier for ultracold Rb 87 atoms using
laser light tuned near the D 2 optical transition. Such a one-way barrier, where atoms …

We report an experimental test of the topological phase predicted by He and McKellar in
1993 and by Wilkens in 1994: this phase, which appears when an electric dipole propagates …
