Topological Pseudo-Goldstone Modes from Weakly Broken Dipole Conservation
Yan-Guang Yue, Jie Lou, Yan Chen
Weakly breaking a continuous symmetry in an ordered phase can convert its Goldstone modes into topological collective bands. We establish this mechanism in a neutral dipole condens…
Studying line defect at Deconfined Quantum Criticality via fuzzy sphere regularization
Shutao Liu, Shuai Yang, Jie Lou +1
The interplay between bulk critical fluctuations and nontrivial topology can enrich defect physics and give rise to novel defect universality classes. Understanding the fate of suc…
Winding-Sector Transitions and Thermodynamic Incommensurability in Helical Valence Bond Phase under Tilted Boundary Conditions
Yan Liu, Jie Lou, Yan Chen
We investigate the ground states of the staircase - model in the maximally anisotropic limit by employing projector quantum Monte Carlo simulations. To overcome b…
Nemotron 3 Ultra: Open, Efficient Mixture-of-Experts Hybrid Mamba-Transformer Model for Agentic Reasoning
NVIDIA, :, Aaron Blakeman +572
We introduce Nemotron 3 Ultra, a 550 billion total and 55 billion active parameter Mixture-of-Experts Hybrid Mamba-Attention language model. We pre-trained Nemotron 3 Ultra on 20 t…
