Climbing the Fusion Tree: Center Ordering and Decoding Hierarchy in Non-Abelian Mixed States
Pablo Sala, Vlad Temkin, Cenke Xu +2
We develop an operational approach to strong-to-weak spontaneous symmetry breaking (sw-SSB) of a non-Abelian symmetry group G. We formulate it as the decoding task of distinguishin…
Particle-Vortex Duality of Hydrodynamics
Cenke Xu, Matthew P. A. Fisher
Equipped with the recently recognized symmetry structure of mixed states of matter and "strong-weak spontaneous symmetry breaking" (SW-SSB), we develop a quantum particle-vortex du…
Observation of Strong-to-Weak Spontaneous Symmetry Breaking in a Dephased Fermi Gas
Si Wang, Thomas G. Kiely, Dorothee Tell +9
Symmetry-based classification of quantum phases of matter is one of the most foundational organizing principles in physics; however, an analogous framework for mixed, decohered qua…
A Guide to Symmetric Mass Generation in Lattice-QCD
Anna Hasenfratz, Cenke Xu
Symmetric mass generation (SMG) has attracted growing interest in both condensed matter theory and lattice-QCD communities. Here we formulate general criteria for SMG and examine t…
Inequality for Strong-Weak Spontaneous Symmetry Breaking in Fermionic Open Quantum systems
Abhijat Sarma, Cenke Xu
Under decoherence, an initial Gaussian (free-fermion) state evolves into a non-Gaussian mixed state, so the resulting decohered fermionic state is not exactly solvable in general.…
Strong-to-Weak Symmetry Breaking in Open Quantum Systems: From Discrete Particles to Continuum Hydrodynamics
Jacob Hauser, Kaixiang Su, Hyunsoo Ha +6
We explore the onset of spontaneous strong-to-weak symmetry breaking (SW-SSB) under U(1)-symmetric (i.e., charge-conserving) open-system dynamics. We define this phenomenon for qua…
Non-invertible bosonic chiral symmetry on the lattice
Lukasz Fidkowski, Cenke Xu, Carolyn Zhang
In this work we realize the 3 + 1 dimensional non-invertible chiral symmetry generator as an operator in a many body lattice Hilbert space. A crucial ingredient in…
Fluctuation-Dissipation Theorem and Information Geometry in Open Quantum Systems
Jian-Hao Zhang, Cenke Xu, Yichen Xu
We propose a fluctuation-dissipation theorem in open quantum systems from an information-theoretic perspective. We define the fidelity susceptibility that measures the sensitivity…
Strong-to-weak spontaneous breaking of 1-form symmetry and intrinsically mixed topological order
Carolyn Zhang, Yichen Xu, Jian-Hao Zhang +3
Topological orders in 2+1d are spontaneous symmetry-breaking (SSB) phases of 1-form symmetries in pure states. The notion of symmetry is further enriched in the context of mixed st…
Two-orbital SU(N) magnetism with ultracold alkaline-earth atoms
A. V. Gorshkov, M. Hermele, V. Gurarie +7
Fermionic alkaline-earth atoms have unique properties that make them attractive candidates for the realization of novel atomic clocks and degenerate quantum gases. At the same time…
