Matrix Density Waves and Fractionally Charged Point Defects in Flavor Weyl Semimetals
Shantonu Mukherjee, Hridis K. Pal
A conventional interaction-driven Weyl density wave is a complex scalar and supports vortex lines, but no topologically stable point defects. We show that two Weyl flavors do not m…

Anomalous Chiral Anomaly in Spin-1 Fermionic Systems
Shantonu Mukherjee, Sayantan Sharma, Hridis K. Pal
Chiral anomaly is a key feature of Lorentz-invariant quantum field theories: in presence of parallel external electric and magnetic fields, the number of massless Weyl fermions of…

Interacting ground states of moiré ladders
Paban Kumar Patra, Ranjith R. Kumar, Yixuan Huang +1
Moiré materials have emerged as a rich platform for exploring strong correlation effects in low dimensions, with twisted bilayer graphene (TBG) as a paradigmatic example. To distil…
