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 Argüello-Luengo, Javier Rivera-Dean +3
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(…
Optical lattice quantum simulator of dynamics beyond Born-Oppenheimer
Javier Argüello-Luengo, Alejandro González-Tudela, J. Ignacio Cirac
Here, we propose a platform based on ultra-cold fermionic molecules trapped in optical lattices to simulate nonadiabatic effects, as they appear in certain molecular dynamical prob…
Eigenstate Thermalization and its breakdown in Quantum Spin Chains with Inhomogeneous Interactions
Ding-Zu Wang, Hao Zhu, Jian Cui +5
The eigenstate thermalization hypothesis (ETH) is a successful theory that establishes the criteria for ergodicity and thermalization in isolated quantum many-body systems. In this…
Engineering and harnessing long-range interactions for atomic quantum simulators
Javier Argüello-Luengo
Interactions between quantum particles, such as electrons, are the source of important effects, ranging from superconductivity, to the formation of molecular bonds, or the stabilit…
Competing order in two-band Bose-Hubbard chains with extended-range interactions
Yuma Watanabe, Utso Bhattacharya, Ravindra W. Chhajlany +3
Motivated by the recent progress in realizing and controlling extended Bose-Hubbard systems using excitonic or atomic devices, the present Letter theoretically investigates the cas…
