Finding purifications with minimal entanglement
Johannes Hauschild, Eyal Leviatan, Jens H. Bardarson +3
Purification is a tool that allows to represent mixed quantum states as pure states on enlarged Hilbert spaces. A purification of a given state is not unique and its entanglement s…
Imaging anyons with scanning tunneling microscopy
Zlatko Papić, Roger S. K. Mong, Ali Yazdani +1
Anyons are exotic quasi-particles with fractional charge that can emerge as fundamental excitations of strongly interacting topological quantum phases of matter. Unlike ordinary fe…
Entanglement of purification: from spin chains to holography
Phuc Nguyen, Trithep Devakul, Matthew G. Halbasch +2
Purification is a powerful technique in quantum physics whereby a mixed quantum state is extended to a pure state on a larger system. This process is not unique, and in systems com…
Quantum dynamics of thermalizing systems
Christopher David White, Michael Zaletel, Roger S. K. Mong +1
We introduce a method "DMT" for approximating density operators of 1D systems that, when combined with a standard framework for time evolution (TEBD), makes possible simulation of…
Observation of fractional Chern insulators in a van der Waals heterostructure
Eric M. Spanton, Alexander A. Zibrov, Haoxin Zhou +4
Topologically ordered phases are characterized by long-range quantum entanglement and fractional statistics rather than by symmetry breaking. First observed in a fractionally fille…
Lattice Homotopy Constraints on Phases of Quantum Magnets
Hoi Chun Po, Haruki Watanabe, Chao-Ming Jian +1
The Lieb-Schultz-Mattis (LSM) theorem and its extensions forbid trivial phases from arising in certain quantum magnets. Constraining infrared behavior with the ultraviolet data enc…
