- Nature
- 22 July 2014

Ultracold atoms in optical lattices have great potential to contribute to a better understanding of some of the most important issues in many-body physics, such as high-temperature superconductivity.… Expand

First-order isostructural Mott transition in highly compressed MnO.

- C. S. Yoo, B. Maddox, +9 authors W. Pickett
- Physics, Medicine
- Physical review letters
- 22 March 2005

We present evidence for an isostructural, first-order Mott transition in MnO at 105+/-5 GPa, based on high-resolution x-ray emission spectroscopy and angle-resolved x-ray diffraction data. The… Expand

Mott domains of bosons confined on optical lattices.

- G. Batrouni, V. Rousseau, +4 authors M. Troyer
- Physics, Medicine
- Physical review letters
- 5 March 2002

In the absence of a confining potential, the boson-Hubbard model exhibits a superfluid to Mott insulator quantum phase transition at commensurate fillings and strong coupling. We use quantum Monte… Expand

Local quantum criticality in confined fermions on optical lattices.

- M. Rigol, A. Muramatsu, G. Batrouni, R. Scalettar
- Physics, Medicine
- Physical review letters
- 1 April 2003

Using quantum Monte Carlo simulations, we show that the one-dimensional fermionic Hubbard model in a harmonic potential displays quantum critical behavior at the boundaries of a Mott-insulating… Expand

Numerical Methods for Quantum Monte Carlo Simulations of the Hubbard Model

- Z. Bai, Wenbin Chen, R. Scalettar, I. Yamazaki
- Physics
- 1 June 2009

One of the core problems in materials science is how the interactions between electrons in a solid give rise to properties like ∗This work was partially supported by the National Science Foundation… Expand

Revisiting the Theory of Finite Size Scaling in Disordered Systems

- F. Pázmándi, R. Scalettar, G. Zimányi
- Materials Science, Physics
- 17 April 1997

For phase transitions in disordered systems, an exact theorem provides a bound on the finite size correlation length exponent: ${\ensuremath{\nu}}_{\mathrm{FS}}\ensuremath{\ge}2/d$. It is believed… Expand

Effect of strong correlations on the high energy anomaly in hole- and electron-doped high-Tc superconductors

- B. Moritz, F. Schmitt, +8 authors T. Devereaux
- Physics
- 21 July 2008

Recently, angle-resolved photoemission spectroscopy (ARPES) has been used to highlight an anomalously large band renormalization at high binding energies in cuprate superconductors: the high energy… Expand

Discovering phases, phase transitions, and crossovers through unsupervised machine learning: A critical examination.

- Wenjian Hu, R. P. Singh, R. Scalettar

- Physics
- 12 April 2005

We apply a first-order reversal curvesFORCd diagram analysis to a perpendicular nickel nanopillar array. We find that the FORC diagram signature of this system consists of a two-branch “wishbone”… Expand

Thermodynamic and spectral properties of compressed Ce calculated using a combined local-density approximation and dynamical mean-field theory
