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…
Hierarchical Trion Formation and Fractionalized Solitons in One Dimension
Yan-Guang Yue, Qi Song, Jie Lou +1
Stabilizing commensurate trions in one-dimensional quantum mixtures is typically hindered by phase separation. Within the conventional density-driven framework, the asymmetri…
Nemotron 3 Ultra: Open, Efficient Mixture-of-Experts Hybrid Mamba-Transformer Model for Agentic Reasoning
NVIDIA, :, Aaron Blakeman +571
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…
Spectroscopic evidences for the spontaneous symmetry breaking at the deconfined critical point of - model
Shutao Liu, Yan Liu, Chengkang Zhou +5
Recent numerical and theoretical studies on the two-dimensional - model suggests that the deconfined quantum critical point is actually a -symmetry-enhanced first-or…
Condensation of Composite Bosonic Trions in Interacting Bose-Fermi Mixtures
Qi Song, Jie Lou, Yan Chen
We reveal a quantum coherent state characterized by composite bosonic trions, wherein paired fermions further bind with bosons, in one-dimensional Bose-Fermi mixtures.This phase em…
Ground State Phase Diagram of - Chain
Junhao Zhang, Jie Hou, Jie Lou +1
Distinct from the case, the fermionic systems with symmetry are expected to exhibit novel physics, such as exotic singlet formation. Using the density…
