Quantized Chern-Simons Axion Coupling in Anomalous Floquet Systems
Lucila Peralta Gavensky, Nathan Goldman, Gonzalo Usaj
Quantized bulk response functions are hallmark signatures of topological phases, but their manifestation in periodically driven (Floquet) systems is not yet fully established. Here…
Charge and spin transport in nanoscopic structures with spin-orbit coupling
A. A. Reynoso, G. Usaj, C. A. Balseiro
During the last years there has been much interest, and theoretical discussion, about the possibility to use spin-orbit coupling to control the carriers spins in two-dimensional se…
The Streda Formula for Floquet Systems: Topological Invariants and Quantized Anomalies from Cesaro Summation
Lucila Peralta Gavensky, Gonzalo Usaj, Nathan Goldman
The Středa formula establishes a fundamental connection between the topological invariants characterizing the bulk of topological matter and the presence of gapless edge modes. In…
Multi-terminal Josephson junctions: a road to topological flux networks
Lucila Peralta Gavensky, Gonzalo Usaj, C. A. Balseiro
Multi-terminal Josephson junctions were recently proposed as a versatile and tunable platform to emulate topological Bloch-like Hamiltonians in arbitrary dimensions. In this perspe…
Dynamical phases transitions in periodically driven Bardeen-Cooper-Schrieffer systems
H. P. Ojeda Collado, Gonzalo Usaj, C. A. Balseiro +2
We present a systematic study of the dynamical phase diagram of a periodically driven BCS system as a function of drive strength and frequency. Three different driving mechanism ar…
Optomechanical parametric oscillation of a quantum light-fluid lattice
A. A. Reynoso, G. Usaj, D. L. Chafatinos +6
Two-photon coherent states are one of the main building pillars of non-linear and quantum optics. It is the basis for the generation of minimum-uncertainty quantum states and entan…
