SSRL X-rays help Illuminate Frustrated Spin Liquid State
ثبت نشده
چکیده
A new magnetic state called a quantum spin liquid has been observed by a large international team of investigators from ten institutions, including a group using SSRL. When magnetic ions are located within a crystal lattice there are usually strong local magnetic and electric forces between them. At low temperatures such forces lead to a preferred alignment of the atomic moments – in ferromagnets such as iron for example, the atomic magnets are aligned parallel to each other while in anti-ferromagnets they are antiparallel. In other cases the atomic magnetics are aligned along crystallographic axis within the crystal. So quite generally when cooled sufficiently, the atomic moments develop a definite alignment.

Modified Spin Wave Thoery of the Bilayer Square Lattice Frustrated Quantum Heisenberg Antiferromagnet
The ground state of the square lattice bilayer quantum antiferromagnet with nearest and next-nearest neighbour intralayer interaction is studied by means of the modified spin wave method. For weak interlayer coupling, the ground state is found to be always magnetically ordered while the quantum disordered phase appear for large enough interlayer coupling. The properties of the disordered phase ...
متن کاملHidden frustrated interactions and quantum annealing in trapped-ion spin-phonon chains
We show that a trapped-ion chain interacting with an optical spin-dependent force shows strong frustration effects due to the interplay between long range interactions and the dressing by optical phases. We consider a strong spin-phonon coupling regime and predict a quantum phase diagram with different competing magnetic and structural orders. In a highly frustrated region, the system shows enh...

Quantum spinmodels with spatially dependent interactions, known as compassmodels, play an important role in the study of frustrated quantummagnetism.One example is theKitaevmodel on the honeycomb lattice with spin-liquid (SL) ground states and anyonic excitations. Another example is the geometrically frustrated quantum120°model on the same lattice whose ground state has not been unambiguously e...
متن کاملSynthesis and Characterization of Single Crystal Kagome Lattice
An ideal spin-% kagom6 lattice has been a long sought material. This system is characterized by strong magnetic frustration and is a likely candidate for a spin-liquid ground state. The spin-liquid state was originally proposed to exist in the parent compounds of the high temperature superconducting cuprates as originally proposed by Anderson. However, the lack of ideal samples have hampered ex...
