Realization of uniform synthetic magnetic fields by periodically shaking an optical square lattice. Creffield, Charles Pieplow, G. Sols Lucía, Fernando Goldman, N. Shaking a lattice system, by modulating the location of its sites periodically in time, is a powerful method to create effective magnetic fields in engineered quantum systems, such as cold gases trapped in optical lattices. However, such schemes are typically associated with space-dependent effective masses (tunneling amplitudes) and non-uniform flux patterns. In this work we investigate this phenomenon theoretically, by computing the effective Hamiltonians and quasienergy spectra associated with several kinds of lattice-shaking protocols. A detailed comparison with a method based on moving lattices, which are added on top of a main static optical lattice, is provided. This study allows the identification of novel shaking schemes, which simultaneously provide uniform effective mass and magnetic flux, with direct implications for cold-atom experiments and photonics. 2023-06-17T21:52:37Z 2023-06-17T21:52:37Z 2023-06-17T21:52:37Z 2016-09-06 journal article https://hdl.handle.net/20.500.14352/17703 1367-2630 10.1088/1367-2630/18/9/093013 eng FIS2013-41716-P MAT2014-58241-P SEV-2015-0522 FOQUS FIS2013- 46768 PAI Project No. P7/18 DYGEST https://creativecommons.org/licenses/by/3.0/es/ open access Atribución 3.0 España IOP Publishing
