11:00am – 12:00pm, Room: GSB 306Repulsively Bound Magnon Excitations of a Spin-1/2 XXZ Chain in a Staggered Transverse Field
Motivated by the chain antiferromagnet BaCo2V208, we study the excitation spectrum of the one-dimensional spin-1/2 XXZ chain with antiferromagnetic Ising anisotropy across a magnetic quantum phase transition induced by the application of a site-dependent transverse magnetic field. Considering a situation where the transverse magnetic field has a strong uniform component and a weaker staggered part, we determine the nature of the excitations giving rise to the spin dynamical structure factor using a combination of analytical approaches and the numerically exact time-dependent matrix product state method. Below the quantum phase transition, we identify high-energy many-body two-magnon and three-magnon repulsively bound states which are clearly visible due to the staggered component of the magnetic field. At high magnetic fields and low temperature, single magnons dominate the dynamics. These results are in very good agreement with terahertz spectroscopy measurements. -

Save The Date – April 23 at 11am – R. Shankar’s Seminar on The Unfinished Theory of Topological Quantised Conductances

11:00am, Room: GSB 408The Unfinished Theory of Topological Quantised conductances
Abstract:
After the discovery of the Quantum Hall Effect more than four decades ago, concepts of topology were successfully applied to understand it. Consequently, several other similar systems, Chern insulators, topological insulators were predicted and experimentally found. However, it is still not fully understood how the topology manifests as quantised conductances in open systems, namely samples coupled to metallic leads.
In this talk we first review the relevant developments of the past decades. We then describe our attempts to understand the system coupled to leads within the framework of a simple microscopic model -
