T1-5/T1-7 Strong Correlations in Cold atoms (DAMOPC/DCMMP) | Corrélations fortes dans les atomes froids (DPAMPC/DPMCM)
- Steve Dodge (Simon Fraser University)
Description
A joint session of the Quantum Materials and Optical Sciences Symposia to showcase research on strong correlations in cold atomic systems.
If a single spin in a spin chain is suddenly flipped, the information regarding the disturbance propagates outwards at a maximum speed given by the Lieb-Robinson bound. This results in a light-cone-like structure in the space-time dependence of correlation functions which has been observed in experiments with cold atoms and ions. In this talk I will show that these ``light cones’’ are examples...
The exquisite control available in ultracold quantum gas experiments has enabled the emulation of many different quantum systems and allowed us to better understand the many-body states of quantum matter. Using the technique of artificial gauge fields, a spatially- and spin-dependent gauge potential $A_{\sigma}(\vec{r})$ can be engineered in a BEC, in which the kinetic energy is modified from...
Dissipation of electrical current in typical metals is due to scattering off material defects and phonons. But what if the material were a perfect crystal, and sufficiently stiff or cold to eliminate phonons -- would conductivity become infinite? We realize an analogous scenario with atomic fermions in a cubic optical lattice, and measure conductivity. The equivalent of Ohm's law for neutral...
