Field-induced quantum soliton lattice in a frustrated two-leg spin-1/2 ladder
F. Casola, T. Shiroka, A. Feiguin +10
The field-induced quantum phase transitions (QPT) of the spin ladder material Bi(Cu(1-x)Znx)2PO6 have been investigated via 31P nuclear magnetic resonance (NMR) on single-crystal s…
Quantum liquid with strong orbital fluctuations: the case of a pyroxene family
A. Feiguin, A. M. Tsvelik, Weiguo Yin +1
We discuss quasi one-dimensional magnetic Mott insulators of the pyroxene family where spin and orbital degrees of freedom remain tightly bound. We analyze their excitation spectru…
Doped Stripes in Models for the Cuprates Emerging from the One-hole Properties of the Insulator
G. B. Martins, C. Gazza, J. C. Xavier +2
The extended and standard t-J models are computationally studied on ladders and planes, with emphasis on the small J/t region. At couplings compatible with photoemission results fo…
Dimensional crossover of spin chains in a transverse staggered field: an NMR study
F. Casola, T. Shiroka, V. Glazkov +6
Heisenberg spin-1/2 chain materials are known to substantially alter their static and dynamic properties when experiencing an effective transverse staggered field originating from…
The ALPS project release 2.0: Open source software for strongly correlated systems
B. Bauer, L. D. Carr, H. G. Evertz +29
We present release 2.0 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an open source software project to develop libraries and application programs for the…
Phase separation of trapped spin-imbalanced Fermi gases in one-dimensional optical lattices
F. Heidrich-Meisner, G. Orso, A. Feiguin
We calculate the density profiles of a trapped spin-imbalanced Fermi gas with attractive interactions in a one-dimensional optical lattice, using both the local density approximati…
