Axiomatic quantum field theory in curved spacetime
, 2008
"... The usual formulations of quantum field theory in Minkowski spacetime make crucial use of features—such as Poincare invariance and the existence of a preferred vacuum state—that are very special to Minkowski spacetime. In order to generalize the formulation of quantum field theory to arbitrary globa ..."

The Thermodynamics of the XXZ Heisenberg Chain with Impurities
, 1999
"... In this paper, we discuss the effect of the arbitrary spin impurities to the spin1/2 and spin1 XXZ model. The effect of ground state, the free energy, the magnetic susceptibility, the specific heat and the Kondo temperature are given by using the thermodynamic Bethe ansatz equation. ..."

Magnetoresistance in the sd Model with Arbitrary Impurity Spin
, 2004
"... The magnetoresistance, the number of the localized electrons, and the swave scattering phase shift at the Fermi level for the sd model with arbitrary impurity spin are obtained in the ground state. To obtain above results some known exact results of the Bethe ansatz method are used. As the impurit ..."

Bethe Ansatz for Quantum Strings
, 2004
"... We propose Bethe equations for the diagonalization of the Hamiltonian of quantum strings on AdS5×S 5 at large string tension and restricted to certain large charge states from a closed su(2) subsector. The ansatz differs from the recently proposed allloop gauge theory asymptotic Bethe ansatz by add ..."

by additional factorized scattering terms for the local excitations. We also show that our ansatz quantitatively reproduces everything that is currently known about the string spectrum of these states. Firstly, by construction, we recover the integral Bethe equations describing semiclassical spinning strings
Entanglement of Formation of an Arbitrary State of Two Qubits
, 1998
"... The entanglement of a pure state of a pair of quantum systems is defined as the entropy of either member of the pair. The entanglement of formation of a mixed state ρ is defined as the minimum average entanglement of a set of pure states constituting a decomposition of ρ. An earlier paper [Phys. Rev ..."

. Rev. Lett. 78, 5022 (1997)] conjectured an explicit formula for the entanglement of formation of a pair of binary quantum objects (qubits) as a function of their density matrix, and proved the formula to be true for a special class of mixed states. The present paper extends the proof to arbitrary

DiamondSpin: An extensible toolkit for aroundthetable interaction
 In Proc. CHI 2004
, 2004
"... DiamondSpin is a toolkit for the efficient prototyping of and experimentation with multiperson, concurrent interfaces for interactive shared displays. In this paper, we identify the fundamental functionality that tabletop user interfaces should embody, then present the toolkit’s architecture and AP ..."

and API. DiamondSpin provides a novel realtime polar to Cartesian transformation engine that has enabled new, aroundthetable interaction metaphors to be implemented. DiamondSpin allows arbitrary document positioning and orientation on a tabletop surface. Polygonal tabletop layouts such as rectangular
Impurity Spin Coupled to Strongly Correlated Electron System: Ground State Properties
, 1994
"... Exact results are provided for the ground state properties of an impurity spin coupled to a conducting band of strongly correlated electrons described by a tJ model. The ground states are proved to be unique, apart from the spin rotational degeneracy, and the ground state spins are found in the fol ..."

in the following case: (1) J = 0, one hole hopping on a lattice in dimensions d ≥ 2. (2) J ̸ = 0, arbitrary number of holes hopping on a one dimensional lattice, i.e., a Luttinger liquid interacting with a localized impurity spin.
Spin ladders with nonmagnetic impurities
, 1996
"... We investigate antiferromagnetic spin ladders with nonmagnetic impurities by variational and numerical (Lanczos and DMRG) methods. The interaction between the two unpaired spins opposite to the impurities is described by an effective exchange interaction Jeff, the magnitude of which depends on the i ..."
