Spin-orbit physics in the Mott regime
Speaker(s): Leon Balents
Abstract: Recent theory and experiment have revealed that strong spin-orbit coupling (SOC) can have dramatic qualitative effects on weakly interacting electrons. For instance, it leads to a distinct phase of matter, the topological band insulator. I will discuss the combined effects of SOC and strong electron... read more

NMR Investigation of Iron-Based High Tc Superconductors
Speaker(s): Takashi Imai
Abstract: I will discuss NMR study of two types of iron based superconductors, electron doped Ba(Fe,Co)2As2 and stoichiometric FeSe. The primary focus will be on normal state spin fluctuations and its possible relation with the superconducting mechanism, and the pairing symmetry as probed by NMR.

Review on Electronic Nematicity and Beyond
Speaker(s): Hae-Young Kee
Abstract: In correlated electron systems, electrons can organize themselves in states that are analogous to classical liquid crystal phases. The search for such phases in solid state systems, in particular for the quantum version of an anisotropic liquid crystal state, dubbed electronic nematic phase, has bee... read more

Phase Transitions in Planar Pyrochlores
Speaker(s): Bruce Gaulin
Abstract: Frustrated pyrochlore magnets with Ising-like moments have attracted much attention due to the spin ice and spin liquid disordered states these materials display at low temperatures. We recently focused attention on Er2Ti2O7 and Yb2Ti2O7 which possess local XY, or planar, moments on the pyrochlore l... read more

Kinetics of Microstructural Transitions in Block Copolymer Melts
Speaker(s): Robert Wickham
Abstract: Soft materials are dynamical by nature and the study of the dynamics of soft materials is an exciting, rich area of current interest. During macromolecular self-assembly, as occurs in block copolymers, long structural relaxation timescales due to collective molecular motion are often seen. How micro... read more

Electronic Structure of the Heavy-fermion Material URu2Si2
Speaker(s): Mohammad Hamidian
Abstract: The heavy fermion URu2Si2 boasts a 25 year old mystery. Its ''hidden order'' phase transition at Tc=17.5K has eluded the onslaught of theory and experiment to describe the complex underlying mechanism. Whether the transition is due to conventional ordering of k-space heavy electrons or to a change i... read more

Fractional Quantum Hall Effect and Featureless Mott Insulators
Speaker(s): Anton Burkov
Abstract: We point out and explicitly demonstrate a close connection that exists between featureless Mott insulators and fractional quantum Hall liquids. Using magnetic Wannier states as the single-particle basis in the lowest Landau level (LLL), we demonstrate that the Hamiltonian of interacting bosons in th... read more
