<\/div><\/i><\/i><\/span>QUANTUM SPIN SYSTEMS<\/span><\/a><\/h4><\/div>\nQuantum spin systems comprise two research thrusts within RQMP:<\/p>\n
i) single- or few-spin systems for quantum information and metrology;
ii) large-scale spin systems.<\/p>\n
Single or few-spin systems contained within quantum dots or bound to localized defects offer compact, highly coherent quantum bits.<\/p>\n
RQMP researchers are exploring new mechanisms and architectures for controlling, coupling, and detecting spin qubits, and exploiting their coherence to develop sensitive magnetometers. Even with surprisingly simple models, large-scale quantum spin systems can exhibit incredibly rich emergent behaviour.<\/p>\n
The combination of strong quantum fluctuations and magnetic frustration can lead to a quantum spin liquid \u2013 a highly entangled state of matter that exhibits fractional excitation.<\/p>\n
In some cases, these excitation could provide a platform for robustly encoding quantum information. For example, Majorana fermions may have been detected recently by a thermal Hall measurement in a Kitaev spin liquid material.

In most cases, the topology is related to an interesting spin\/pseudospin structure in momentum space enabled by significant spin-orbit coupling. The hallmark of topology is surface states that are robust to disorder. These surface states hold great promise for defect-tolerant devices and are a stepping-stone towards fault-tolerant qubits for quantum computing and low-dissipation spintronic devices.<\/p>\n

Many tools have already been commercialized and used by researchers and engineers in the world. RQMP researchers develop very advanced and powerful multi-scale multi-physics material theories and simulation tools, going all the way from atomistic modelling such as density functional theory, to continuum modelling, such as :<\/p>\n
\n- phase field methods;<\/li>\n
- large-scale molecular dynamics and ab initio molecular dynamics, as well as Monte Carlo simulations;<\/li>\n
- covering the physics of both ground states and excited states;<\/li>\n
- equilibrium as well as nonequilibrium;<\/li>\n

- modelling electronic, topological, transport, mechanic, photonic, magnetic and biologic systems;<\/li>\n
- as well as simulation tools for advanced experimental techniques such as SPM.<\/li>\n<\/ul>\n
Very strong effort will be devoted to integrating our theoretical methods and tools into powerful and unique computational platforms so that our experimental colleagues can easily access them for specific applications.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

some ~400,000 different bulk materials have already been discovered in nature or synthesised by hand. Adding molecules and sequences, the number goes to beyond 140 million.
However, and surprisingly, a very little part about their physical properties is known. Clearly, existing materials present a huge opportunity of applications if their properties can be quickly found.<\/p>\n
In this regard, RQMP researchers have developed several tools for material informatics, assisted by machine learning, to screen material candidates having a particular physical property very efficiently, from the huge materials databases.<\/p>\n
Machine learning methods have also been developed by RQMP researchers for accelerating other simulation tools, to build deep potential for materials, to assistant ab initio molecular dynamics, to determine structural properties of disordered systems. Again, RQMP will be able to develop the most powerful tools based on machine learning, with direct experimental verification from our labs and theoretical verification from our simulation methods.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
