Pair-Density-Wave in the Strong Coupling Limit of the Holstein-Hubbard model
Kevin S. Huang, Zhaoyu Han, Steven A. Kivelson +1
A pair-density-wave (PDW) is a novel superconducting state with an oscillating order parameter. A microscopic mechanism that can give rise to it has been long sought but has not ye…
Numerical Study of a Dual Representation of the Integer Quantum Hall Transition
Kevin S. Huang, S. Raghu, Prashant Kumar
We study the critical properties of the non-interacting integer quantum Hall to insulator transition (IQHIT) in a "dual" composite-fermion (CF) representation. A key advantage of t…
Strong Coupling Limit of the Holstein-Hubbard Model
Zhaoyu Han, Steven A. Kivelson, Hong Yao
We analyze the quantum phase diagram of the Holstein-Hubbard model using an asymptotically exact strong-coupling expansion. We find all sorts of interesting phases including a pair…
Annihilation of Domain Walls in a Ferromagnetic Wire
Anirban Ghosh, Kevin S. Huang, Oleg Tchernyshyov
We study the annihilation of topological solitons in the simplest setting: a one-dimensional ferromagnet with an easy axis. We develop an effective theory of the annihilation proce…
