Reply to Comment on "Anomalous Edge State in a Non-Hermitian Lattice" Open
The Comment by Xiong et al. (arXiv:1610.06275) criticizing my Letter [Phys. Rev. Lett. 116, 133903 (2016)] was rejected by Physical Review Letters. In this Reply, I show that all their claims are wrong.

Floquet engineering from long-range to short-range interactions Open
Quantum simulators based on atoms or molecules often have long-range interactions due to dipolar or Coulomb interactions. We present a method based on Floquet engineering to turn a long-range interaction into a short-range one. By modulati…

We study the transverse-field Ising model with interactions that are\nmodulated in time. In a rotating frame, the system is described by a\ntime-independent Hamiltonian with many-body interactions, similar to the\ncluster Hamiltonians of m…

Aubry-Andre Harper (AAH) lattice models, characterized by\nreflection-asymmetric, sinusoidally varying nearest-neighbor tunneling profile,\nare well-known for their topological properties. We consider the fate of such\nmodels in the presen…

We show that the bulk-boundary correspondence for topological insulators can be modified in the presence of non-Hermiticity. We consider a one-dimensional tight-binding model with gain and loss as well as long-range hopping. The system is …

It has been predicted that particles with imaginary mass, called tachyons,\nwould be able to travel faster than the speed of light. There has not been any\nexperimental evidence for tachyons occurring naturally. Here, we propose how to\nex…

Limit-cycle phase in driven-dissipative spin systems Open
We explore the phase diagram of interacting spin-$1/2$ systems in the\npresence of anisotropic interactions, spontaneous decay and driving. We find a\nrich phase diagram featuring a limit cycle phase in which the magnetization\noscillates …

Transport of quantum excitations via local and nonlocal fluctuations Open
In quantum systems, one usually seeks to minimize dephasing noise and\ndisorder. The efficiency of transport in a quantum system is usually degraded\nby the presence of noise and disorder. However, it has been shown that the\ncombination o…
