Kaleidoscope of quantum phases in a long-range interacting spin-1 chain
Zhe-Xuan Gong, Mohammad F. Maghrebi, Anzi Hu +4
Motivated by recent trapped-ion quantum simulation experiments, we carry out a comprehensive study of the phase diagram of a spin-1 chain with XXZ-type interactions that decay as $…
Continuous symmetry breaking and a new universality class in 1D long-range interacting quantum systems
Mohammad F. Maghrebi, Zhe-Xuan Gong, Alexey V. Gorshkov
Continuous symmetry breaking (CSB) in low-dimensional systems, forbidden by the Mermin-Wagner theorem for short-range interactions, may take place in the presence of slowly decayin…
Causality and quantum criticality in long-range lattice models
Mohammad F. Maghrebi, Zhe-Xuan Gong, Michael Foss-Feig +1
Long-range quantum lattice systems often exhibit drastically different behavior than their short-range counterparts. In particular, because they do not satisfy the conditions for t…
Simulating the Haldane Phase in Trapped Ion Spins Using Optical Fields
I. Cohen, P. Richerme, Z. -X. Gong +2
We propose to experimentally explore the Haldane phase in spin-one XXZ antiferromagnetic chains using trapped ions. We show how to adiabatically prepare the ground states of the Ha…
Topological phases with long-range interactions
Zhe-Xuan Gong, Mohammad F. Maghrebi, Anzi Hu +3
Topological phases of matter are primarily studied in systems with short-range interactions. In nature, however, non-relativistic quantum systems often exhibit long-range interacti…
