Quantum kinetics of refocusing
Leonid P. Pryadko, Pinaki Sengupta
We consider quantum kinetics of an open quantum system in the presence of periodic fields designed to suppress the internal evolution and shield the system from generic low-frequen…
Scalable design of tailored soft pulses for coherent control
Pinaki Sengupta, Leonid P. Pryadko
We present a scalable scheme to design optimized soft pulses and pulse sequences for coherent control of interacting quantum many-body systems. The scheme is based on the cluster e…
Supersolids versus phase separation in two-dimensional lattice bosons
Pinaki Sengupta, Leonid P. Pryadko, Fabien Alet +2
We study the nature of the ground state of the strongly-coupled two dimensional extended boson Hubbard model on a square lattice. We demonstrate that strong but finite on-site inte…
Neel to spin-Peierls transition in the ground state of a quasi-1D Heisenberg model coupled to bond phonons
Pinaki Sengupta
The spin-Peierls transition in the ground state of a quasi-one-dimensional spin-1/2 Heisenberg model coupled to adiabatic bond phonons is studied using a quantum Monte Carlo (QMC)…
Comment on ``Ground State Phase Diagram of a Half-Filled One-Dimensional Extended Hubbard Model''
A. W. Sandvik, P. Sengupta, D. K. Campbell
In Phys. Rev. Lett. 89, 236401 (2002), Jeckelmann argued that the recently discovered bond-order-wave (BOW) phase of the 1D extended Hubbard model does not have a finite extent in…
