Non-Hermitian Numerical Renormalization Group - Solution of the Non-Hermitian Kondo Model

Learn to solve the non-Hermitian Kondo model using a novel numerical renormalization group approach in this 35-minute conference talk. Explore how non-Hermitian Hamiltonians describe open quantum systems, nonequilibrium dynamics, and dissipative processes, while discovering why many-body phenomena in strongly correlated non-Hermitian systems remain understudied compared to single-particle physics. Examine the Kondo effect as a crucial paradigm for strong correlation physics in the non-Hermitian setting. Understand the development of a non-Hermitian generalization of the numerical renormalization group (NRG) method and its application to solving the non-Hermitian Kondo model. Discover how this non-perturbative solution extends beyond weak coupling regimes and reveals a nontrivial phase diagram, advancing the understanding of strongly correlated quantum systems with dissipative effects.
