Giant orbital magnetoresistance in the antiferromagnet CoO driven by dynamic orbital angular momentum interaction
Christin Schmitt, Sachin Krishnia, Edgar Galindez-Ruales +12
Recent predictions of orders of magnitude larger orbital current effects compared to spin currents have attracted significant interest. However, the full potential of giant orbital…
Measuring quantized circular dichroism in ultracold topological matter
Luca Asteria, Duc Thanh Tran, Tomoki Ozawa +6
The topology of two-dimensional materials traditionally manifests itself through the quantization of the Hall conductance, which is revealed in transport measurements. Recently, it…
Quantized Rabi Oscillations and Circular Dichroism in Quantum Hall Systems
Duc Thanh Tran, Nigel R. Cooper, Nathan Goldman
The dissipative response of a quantum system upon a time-dependent drive can be exploited as a probe of its geometric and topological properties. In this work, we explore the impli…
Probing topology by "heating": Quantized circular dichroism in ultracold atoms
D. T. Tran, A. Dauphin, A. G. Grushin +2
We reveal an intriguing manifestation of topology, which appears in the depletion rate of topological states of matter in response to an external drive. This phenomenon is presente…
Loading Ultracold Gases in Topological Floquet Bands: Current and Center-of-Mass Responses
A. Dauphin, D. -T. Tran, M. Lewenstein +1
Topological band structures can be designed by subjecting lattice systems to time-periodic modulations, as was recently demonstrated in cold atoms and photonic crystals. However, c…
Topological Hofstadter Insulators in a Two-Dimensional Quasicrystal
Duc-Thanh Tran, Alexandre Dauphin, Nathan Goldman +1
We investigate the properties of a two-dimensional quasicrystal in the presence of a uniform magnetic field. In this configuration, the density of states (DOS) displays a Hofstadte…
