ab initio Study of Strain-Induced Ferroelectricity in SrTiO3
Takatoshi Hashimoto, Takeshi Nishimatsu, Hiroshi Mizuseki +3
Valley lines on total-energy surfaces for the zone-center distortions of free-standing and in-plane strained SrTiO3 are investigated with a newly developed first-principles structu…
Multi-particle entanglement manipulation under positive partial transpose preserving operations
Satoshi Ishizaka, Martin B. Plenio
We consider the transformation of multi-partite states in the single copy setting under positive-partial-transpose-preserving operations (PPT-operations) and obtain both qualitativ…
Carrier-Induced Magnetic Circular Dichloism in the Magnetoresistive Pyrochlore Tl2Mn2O7
H. Okamura, T. Koretsune, S. Kimura +4
Infrared magnetic circular dichloism (MCD), or equivalently magneto-optical Kerr effect, has been measured on the Tl2Mn2O7 pyrochlore, which is well known for exhibiting a large ma…
Ab initio Study of Valley Line on a Total-Energy Surface for Zone-Center Distortions of Ferroelectric Perovskite Oxides BaTiO3 and PbTiO3
Takeshi Nishimatsu, Takatoshi Hashimoto, Hiroshi Mizuseki +3
An ab initio structure optimization technique is newly developed to determine the valley line on a total-energy surface for zone-center distortions of ferroelectric perovskite oxid…
Bound entanglement provides convertibility of pure entangled states
Satoshi Ishizaka
I show that two distant parties can transform pure entangled states to arbitrary pure states by stochastic local operations and classical communication (SLOCC) at the single copy l…
