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…
Non-equilibrium transport through a point contact in the non-Abelian quantum Hall state
Adrian Feiguin, Paul Fendley, Matthew P. A. Fisher +1
We analyze charge- quasiparticle tunneling between the edges of a point contact in a non-Abelian model of the quantum Hall state. We map this problem to resonant tunne…
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…
Strong-Coupling Phases of Frustrated Bosons on a 2-leg Ladder with Ring Exchange
D. N. Sheng, Olexei I. Motrunich, Simon Trebst +2
Developing a theoretical framework to access quantum phases of itinerant bosons or fermions in two dimensions (2D) that exhibit singular structure along surfaces in momentum space…
