Light-cone-like spreading of correlations in a quantum many-body system.
Cheneau M, Barmettler P, Poletti D, Endres M, Schauss P, Fukuhara T, Gross C, Bloch I, Kollath C, Kuhr S. Cheneau M, et al. Among authors: bloch i. Nature. 2012 Jan 25;481(7382):484-7. doi: 10.1038/nature10748. Nature. 2012. PMID: 22281597 Free article.
Interferometric approach to measuring band topology in 2D optical lattices.
Abanin DA, Kitagawa T, Bloch I, Demler E. Abanin DA, et al. Among authors: bloch i. Phys Rev Lett. 2013 Apr 19;110(16):165304. doi: 10.1103/PhysRevLett.110.165304. Epub 2013 Apr 18. Phys Rev Lett. 2013. PMID: 23679614 Free article.
In this Letter, we propose an interferometric method for measuring Berry's phases of two-dimensional Bloch bands. The key idea is to use a combination of Ramsey interference and Bloch oscillations to measure Zak phases, i.e., Berry's phases for closed traject …
