Quantum transport in a non-Hermitian 1D synthetic lattice: from quantum Zeno reflection to near-perfect absorption
Emmanuel. D. Mercado-Gutiérrez, W. Xu, E. Gvozdiovas +5
We experimentally explore the absorption of a propagating wavepacket impinging upon a dissipative region in an engineered quantum system. We employ a 1D non-Hermitian synthetic lat…
Quantum Kramers-Henneberger Transformation
Javier Argüello-Luengo, Javier Rivera-Dean, Philipp Stammer +2
The classical Kramers-Henneberger transformation connects, via a series of unitary transformations, the dynamics of a quantum particle of mass located in a trap at position $α(…
Probing spontaneously symmetry-broken phases with spin-charge separation through noise correlation measurements
Kerman Gallego-Lizarribar, Sergi Julià-Farré, Maciej Lewenstein +3
Spontaneously symmetry-broken (SSB) phases are locally ordered states of matter characterizing a large variety of physical systems. Because of their specific ordering, their presen…
Quantized Thouless pumps protected by interactions in dimerized Rydberg tweezer arrays
Sergi Julià-Farré, Javier Argüello-Luengo, Loïc Henriet +1
We study Thouless pumps, i.e., adiabatic topological transport, in an interacting spin chain described by the dimerized XXZ Hamiltonian. In the noninteracting case, quantized Thoul…
Synthetic dimensions for topological and quantum phases: Perspective
Javier Argüello-Luengo, Utso Bhattacharya, Alessio Celi +8
In this Perspective article we report on recent progress on studies of synthetic dimensions, mostly, but not only, based on the research realized around the Barcelona groups (ICFO,…
Entanglement and squeezing of the optical field modes in high harmonic generation
Philipp Stammer, Javier Rivera-Dean, Andrew S. Maxwell +5
Squeezing of optical fields, used as a powerful resource for many applications, and the radiation properties in the process of high harmonic generation have thus far been considere…
