Parasitic small-moment-antiferromagnetism and non-linear coupling of hidden order and antiferromagnetism in URu2Si2 observed by Larmor diffraction (2009)

Niklowitz, P. G., Pfleiderer, C., Keller, T., Vojta, M., Mydosh, J. A.

We report simultaneous measurements of the distribution of lattice constants and the antiferromagnetic moment in high-purity URu2Si2, using both Larmor and conventional neutron diffraction, as a...

Pressure dependence of the magnetization of URu2Si2 (2006)

Pfleiderer, C., Mydosh, J. A., Vojta, M.

The ground state of URu2Si2 changes from so-called hidden order (HO) to large-moment antiferromagnetism (LMAF) upon applying hydrostatic pressure in excess of 14 kbar. We report the dc-magnetization...

Magnetic order in lightly doped cuprates: Coherent versus incoherent hole quasiparticles and nonmagnetic impurities (2006)

Kirćan, M., Vojta, M.

We investigate magnetic properties of lightly doped antiferromagnetic Mott insulators in the presence of nonmagnetic impurities. Within the framework of the t-J model we calculate the doping...

Longitudinal magnon in the tetrahedral spin system Cu2Te2O5Br2 near quantum criticality (2003)

Gros, C., Lemmens, P., Vojta, M., Valenti, R., Kageyama, H., ...

We present a comprehensive study of the coupled tetrahedra-compound Cu2Te2O5Br2 by theory and experiments in external magnetic fields. We report the observation of a longitudinal magnon in Raman...

Quantum Phase Transitions in Models of Magnetic Impurities (2002)

Bulla, R., Vojta, M.

Zero temperature phase transitions not only occur in the bulk of quantum systems, but also at boundaries or impurities. We review recent work on quantum phase transitions in impurity models that are...

Indications of Spin-Charge Separation at Short Distance and Stripe Formation in the Extended t-J Model on Ladders and Planes (2000)

Martins, G. B., Xavier, J. C., Gazza, C., Vojta, M., Dagotto, E.

The recently discussed tendency of holes to generate nontrivial spin environments in the extended two-dimensional t-J model (G. Martins, R. Eder, and E. Dagotto, Phys. Rev. B{\bf 60}, R3716 (1999))...

A Benchmark Suite for Evaluating Configurable Computing Systems (2000)

S. Kumar, L. Pires, S. Ponnuswamy, C. Nanavati, J. Golusky, M. Vojta, ...

This paper presents a benchmark suite for evaluating a configurable computing system’s infrastructure, both tools and architecture. A novel aspect of this work is the use of stressmarks, benchmarks...
