Harnessing spin-qubit decoherence to probe strongly-interacting quantum systems
Marcin Płodzień, Sambunath Das, Maciej Lewenstein +2
Extracting information from quantum many-body systems remains a key challenge in quantum technologies due to experimental limitations. In this work, we employ a single spin qubit t…
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,…
Quantum phase transition in skewed ladders: an entanglement entropy and fidelity study
Sambunath Das, Dayasindhu Dey, S. Ramasesha +1
Entanglement entropy (EE) of a state is a measure of correlation or entanglement between two parts of a composite system and it may show appreciable change when the ground state (G…
Quantum phases of spin-1 system on 3/4 and 3/5 skewed ladders
Sambunath Das, Dayasindhu Dey, S. Ramasesha +1
We study the quantum phase transitions of frustrated antiferromagnetic Heisenberg spin-1 systems on the 3/4 and 3/5 skewed two leg ladder geometries. These systems can be viewed as…
Quantum phases of a frustrated spin-1 system: The 5/7 skewed ladder
Sambunath Das, Dayasindhu Dey, Manoranjan Kumar +1
The quantum phases in a spin-1 skewed ladder system formed by alternately fusing five- and seven-membered rings are studied numerically using the exact diagonalization technique up…
Magnetization plateaus of spin- system on a 5/7 skewed ladder
Dayasindhu Dey, Sambunath Das, Manoranjan Kumar +1
Magnetization plateaus are some of the most striking manifestations of frustration in low-dimensional spin systems. We present numerical studies of magnetization plateaus in the fa…
