Probing spatial spin correlations of ultracold gases by quantum noise spectroscopy. Physical Review Letters 102: 030401.1079-7114http://nrs.harvard.edu/urn-3:HUL.InstRepos:13421124Spin noise spectroscopy with a single laser beam is demonstrated theoretically to provide a direct probe of the spatial correlations of cold fermionic gases. We show how the generic many-body phenomena of anti-bunching, pairing, antiferromagnetic, and algebraic spin liquid correlations can be revealed by measuring the spin noise as a function of laser width, temperature, and frequency.en-USJournal Article2014-11-2410.1103/PhysRevLett.102.030401
