Electronic and magnetic ground states of {112} grain boundary in graphene in the extended Hubbard model
Sishir Jana, Dayasindhu Dey, Manoranjan Kumar +2
We study the ground state phase diagram of the extended Hubbard model in a half-filled 5/7 skewed ladder, which is topologically equivalent to a \{112\} grain boundary in graphene…
Quantum Phase Transitions in Skewed Ladder Systems
Sambunath Das, Dayasindhu Dey, Rajamani Raghunathan +3
In this brief review, we introduce a new spin ladder system called skewed spin ladders and discuss the exotic quantum phases of this system. The spin ladders studied are the 5/7, 3…
Quadrupolar Phases and Plateau States In Skewed Ladders
Sambunath Das, Dayasindhu Dey, Manoranjan Kumar +1
Two legged skewed spin- ladders are frustrated and exhibit exotic quantum phases in ground state due to strong quantum fluctuations and competing spin exchanges. Here,…
