Lightning review on emergent quantum electrodynamics in quantum spin ice
Speaker(s): Yong-Baek Kim
Abstract: We aim to provide a concise review on theoretical background on emergent quantum electrodynamics in pyrochlore quantum spin ice. We first introduce elementary excitations in quantum spin ice using a simple model and then extend the discussion to more realistic systems. Implications to experiments ar... read more

Topological and Broken-Symmetry Phases in Three-dimensional Hyperhoneycomb Iridates
Speaker(s): Yong-Baek Kim
Abstract: Recently three-dimensional versions of honeycomb-lattice iridates, beta and gamma phases of Li2IrO3, have been discovered. It has been theoretically suggested that these hyperhoneycomb iridates may hold promise for the realization of the Kitaev spin liquid or the exactly solvable model for the elusi... read more

Quantum spin liquid phases in the absence of spin-rotation symmetry
Speaker(s): Yong-Baek Kim
Abstract: We investigate possible quantum spin liquid phases in the presence of a variety of spin-rotational-symmetry breaking perturbations. Projective symmetry group analysis on slave-particle representations is used to understand possible spin liquid phases on the Kagome lattice. The results of this analys... read more

Lightning Review on Quantum Spin Liquid
Speaker(s): Yong-Baek Kim
Abstract: We provide a brief introduction to quantum spin liquid and review current status of theoretical and experimental progresses on this subject. Spin liquid phases that arise in different situations are examined in the light of both theoretical models and experimental systems.

Where Are We in Spin Liquid Research?
Speaker(s): Yong-Baek Kim
Abstract: We provide a brief introduction to quantum spin liquid and review current status of theoretical and experimental progresses on this subject. Spin liquid phases that arise in different situations are examined in the light of both theoretical models and experimental systems.

Non-equilibrium drive near a quantum critical point
Speaker(s): Yong-Baek Kim
Abstract: We will discuss the effect of non-equilibrium drive near a quantum critical point in itinerant electron systems. Non-equilibrium field theory is formulated in terms of the Keldysh functional integral. The renormalization group approach is used to study the universality class of the non-equilibr... read more

Spin Liquid and Topological Insulator in Frustrated Magnets
Speaker(s): Yong-Baek Kim
Abstract: Recently several proposals are made for possible spin liquid and topological insulator phases in frustrated magnets. I will review some of these efforts and present some new results. Implications to real materials will also be made.
