Density-and-phase domain walls in a condensate with dynamical gauge potentials
Sayak Bhattacharjee, Roderich Moessner, Shovan Dutta
We show how one can generate domain walls that separate high- and low-density regions with opposite momenta in the ground state of a harmonically trapped Bose-Einstein condensate u…
Generating Symmetry-Protected Long-Range Entanglement in Many-Body Systems
Shovan Dutta, Stefan Kuhr, Nigel R. Cooper
Entanglement between spatially distant qubits is perhaps the most counterintuitive and vital resource for distributed quantum computing. However, despite a few special cases, there…
Density-Matrix Renormalization Group for Continuous Quantum Systems
Shovan Dutta, Anton Buyskikh, Andrew J. Daley +1
We introduce a versatile and practical framework for applying matrix product state techniques to continuous quantum systems. We divide space into multiple segments and generate con…
Realizing discontinuous quantum phase transitions in a strongly-correlated driven optical lattice
Bo Song, Shovan Dutta, Shaurya Bhave +4
Discontinuous quantum phase transitions and the associated metastability play central roles in diverse areas of physics ranging from ferromagnetism to false vacuum decay in the ear…
Quantum walk of two anyons across a statistical boundary
Liam L. H. Lau, Shovan Dutta
We model a quantum walk of identical particles that can change their exchange statistics by hopping across a domain wall in a 1D lattice. Such a "statistical boundary" is transpare…
Out-of-equilibrium steady states of a locally driven lossy qubit array
Shovan Dutta, Nigel R. Cooper
We find a rich variety of counterintuitive features in the steady states of a qubit array coupled to a dissipative source and sink at two arbitrary sites, using a master equation a…
Long-Range Coherence and Multiple Steady States in a Lossy Qubit Array
Shovan Dutta, Nigel R. Cooper
We show that a simple experimental setting of a locally pumped and lossy array of two-level quantum systems can stabilize states with strong long-range coherence. Indeed, by explic…
Coherent generation of photonic fractional quantum Hall states in a cavity and the search for anyonic quasiparticles
Shovan Dutta, Erich J. Mueller
We present and analyze a protocol in which polaritons in a noncoplanar optical cavity form fractional quantum Hall states. We model the formation of these states and present techni…
Protocol to engineer Fulde-Ferrell-Larkin-Ovchinnikov states in a cold Fermi gas
Shovan Dutta, Erich J. Mueller
We propose a two-step experimental protocol to directly engineer Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) states in a cold two-component Fermi gas loaded into a quasi-one-dimensiona…
Collective modes of a soliton train in a Fermi superfluid
Shovan Dutta, Erich J. Mueller
We characterize the collective modes of a soliton train in a quasi-one-dimensional Fermi superfluid, using a mean-field formalism. In addition to the expected Goldstone and Higgs m…
Dimensional Crossover in a Spin-imbalanced Fermi gas
Shovan Dutta, Erich J. Mueller
We model the one-dimension (1D) to three-dimension (3D) crossover in a cylindrically trapped Fermi gas with attractive interactions and spin-imbalance. We calculate the mean-field…
Kinetics of Bose-Einstein condensation in a dimple potential
Shovan Dutta, Erich J. Mueller
We model the dynamics of condensation in a bimodal trap, consisting of a large reservoir region, and a tight "dimple" whose depth can be controlled. Experimental investigations hav…
Variational study of polarons and bipolarons in a 1D Bose lattice gas in both superfluid and Mott regimes
Shovan Dutta, Erich J. Mueller
We use variational methods to study a spin impurity in a 1D Bose lattice gas. Both in the strongly interacting superfluid regime and the Mott regime we find that the impurity binds…
