Electro-nuclear transition into a spatially modulated magnetic state in YbRhSi
J. Knapp, L. V. Levitin, J. Nyéki +7
The nature of the antiferromagnetic order in the heavy fermion metal YbRhSi, its quantum criticality, and superconductivity, which appears at low mK temperatures, remain op…
Quantum Simulation of the Hubbard Model: The Attractive Route
A. F. Ho, M. A. Cazalilla, T. Giamarchi
We study the conditions under which, using a canonical transformation, the phases sought after for the repulsive Hubbard model, namely a Mott insulator in the paramagnetic and anti…
Effect of disorder on a Pomeranchuk instability
A. F. Ho, A. J. Schofield
We study the effect of disorder on the order parameter equation and transition temperature of a Pomeranchuk-type Fermi-surface instability using replica mean field theory. We consi…
Deconfinement and cold atoms in optical lattices
M. A. Cazalilla, A. F. Ho, T. Giamarchi
Despite the fact that by now one dimensional and three dimensional systems of interacting particles are reasonably well understood, very little is known on how to go from the one d…
c-axis transport in highly anisotropic metals: role of small polarons
A. F. Ho, A. J. Schofield
We show in a simple model of interlayer hopping of single electrons, that transport along the weakly coupled c-axis of quasi-two-dimensional metals does not always probe only the i…
Non-trivial fixed point in a twofold orbitally degenerate Anderson impurity model
Michele Fabrizio, Andrew F. Ho, Lorenzo De Leo +1
We study the phase diagram of a twofold orbitally degenerate Anderson impurity model which presents a non-trivial fixed point similar to the two-impurity Kondo model one. Remarkabl…
Small polarons and c-axis transport in highly anisotropic metals
A. F. Ho, A. J. Schofield
Motivated by the anomalous c-axis transport properties of the quasi two-dimensional metal, , and related compounds, we have studied the interlayer hopping of singl…
Bound-State Instability of the Chiral Luttinger Liquid in One-Dimension
A. F. Ho, P. Coleman
We have developed a new boot-strap method for solving a class of interacting one-dimensional chiral fermions. The conventional model for interacting right-moving electrons with spi…
Breakdown of the Chiral Luttinger Liquid in One-Dimension
A. F. Ho, P. Coleman
We have developed a fermionic boot-strap method to solve a class of chiral one dimensional fermion model which cannot be tackled by bosonization. Using this scheme, we show that Lu…
Marginal Fermi Liquid in a lattice of three-body bound-states
A. F. Ho, P. Coleman
We study a lattice model for Marginal Fermi liquid behavior, involving a gas of electrons coupled to a dense lattice of three-body bound-states. The bound-states change the phase s…
