Clustering of steady-state correlations in open systems with long-range interactions

Andrew Y. Guo, Simon Lieu, Minh C. Tran +1

Lieb-Robinson bounds are powerful analytical tools for constraining the dynamic and static properties of non-relativistic quantum systems. Recently, a complete picture for closed s…

Symmetry breaking and error correction in open quantum systems

Simon Lieu, Ron Belyansky, Jeremy T. Young +3

Symmetry-breaking transitions are a well-understood phenomenon of closed quantum systems in quantum optics, condensed matter, and high energy physics. However, symmetry breaking in…

Preserving orbital order in a layered manganite by ultrafast hybridized band excitation

L. Shen, S. Mack, G. Dakovski +19

In the mixed-valence manganites, a near-infrared laser typically melts the orbital and spin order simultaneously, corresponding to the photoinduced $d…

Tenfold Way for Quadratic Lindbladians

Simon Lieu, Max McGinley, Nigel R. Cooper

We uncover a topological classification applicable to open fermionic systems governed by a general class of Lindblad master equations. These `quadratic Lindbladians' can be capture…

Non-Hermitian Majorana modes protect degenerate steady states

Simon Lieu

We introduce non-Hermitian generalizations of Majorana zero modes (MZMs) which appear in the topological phase of a weakly dissipative Kitaev chain coupled to a Markovian bath. Not…

Topological symmetry classes for non-Hermitian models and connections to the bosonic Bogoliubov-de Gennes equation

Simon Lieu

The Bernard-LeClair (BL) symmetry classes generalize the ten-fold way classes in the absence of Hermiticity. Within the BL scheme, time-reversal and particle-hole come in two flavo…
