Decoding Measurement-Prepared Quantum Phases and Transitions: from Ising model to gauge theory, and beyond
Jong Yeon Lee, Wenjie Ji, Zhen Bi +1
Measurements allow efficient preparation of interesting quantum many-body states with long-range entanglement, conditioned on additional transformations based on measurement outcom…
Atypical energy eigenstates in the Hubbard chain and quantum disentangled liquids
Thomas Veness, Fabian H. L. Essler, Matthew P. A. Fisher
We investigate the implications of integrability for the existence of quantum disentangled liquid (QDL) states in the half-filled one-dimensional Hubbard model. We argue that there…
Low-energy behavior of spin-liquid electron spectral functions
Evelyn Tang, Matthew P. A. Fisher, Patrick A. Lee
We calculate the electron spectral function for a spin-liquid with a spinon Fermi surface and a Dirac spin-liquid. Calculations are based upon the slave-rotor mean-field theory. We…
Non-Fermi-liquid d-wave metal phase of strongly interacting electrons
Hong-Chen Jiang, Matthew S. Block, Ryan V. Mishmash +4
Developing a theoretical framework for conducting electronic fluids qualitatively distinct from those described by Landau's Fermi-liquid theory is of central importance to many out…
Spin, Bose, and Non-Fermi Liquid Metals in Two Dimensions: Accessing via Multi-Leg Ladders
Matthew P. A. Fisher, Olexei I. Motrunich, Donna N. Sheng
Characterizing and accessing quantum phases of itinerant bosons or fermions in two dimensions (2D) that exhibit singular structure along surfaces in momentum space but have no quas…
Monopoles in CP(N-1) model via the state-operator correspondence
Max A. Metlitski, Michael Hermele, T. Senthil +1
One of the earliest proposed phase transitions beyond the Landau-Ginzburg-Wilson paradigm is the quantum critical point separating an antiferromagnet and a valence-bond-solid on a…
