Uniform Herding: Exemplar Replay with Representation Refresh
Krishna Subedi
As the feature representation changes, replay must preserve the earlier classes. However, only a bounded active exemplar set can be replayed. We propose Uniform Herding, which allo…
Non-Perturbative Renormalization Group for Ising-Nematic Criticality: A Closed-Form Nonlocal Ansatz
Hyeon Jung Kim, Kyoung-Min Kim, Ki-Seok Kim
The two-dimensional metallic quantum critical problem is a long-standing puzzle that is widely believed to hold the key to resolving ubiquitous non-Fermi liquid behavior in strongl…
Deep learning methods for Hamiltonian parameter estimation and magnetic domain image generation in twisted van der Waals magnets
Woo Seok Lee, Taegeun Song, Kyoung-Min Kim
The application of twist engineering in van der Waals magnets has opened new frontiers in the field of two-dimensional magnetism, yielding distinctive magnetic domain structures. D…
Disordered non-Fermi liquid fixed point for two-dimensional metals at Ising-nematic quantum critical points
Kyoung-Min Kim, Ki-Seok Kim
Understanding the influence of quenched random potential is crucial for comprehending the exotic electronic transport of non-Fermi liquid metals near metallic quantum critical poin…
