Diffusion in quantum state preparation: From passive cooling to system-bath engineering
Tim Pokart, Lukas König, Sebastian Diehl +1
We investigate and compare two particle number-conserving protocols for the preparation of a topologically nontrivial state. The first is derived from thermally coupling the system…
Majorana Modes in Driven-Dissipative Atomic Superfluids With Zero Chern Number
C. -E. Bardyn, M. A. Baranov, E. Rico +3
We investigate dissipation-induced p-wave paired states of fermions in two dimensions and show the existence of spatially separated Majorana zero modes in a phase with vanishing Ch…
Loss-induced phase separation and pairing for 3-species atomic lattice fermions
A. Privitera, I. Titvinidze, S. -Y. Chang +3
We study the physics of a three-component Fermi gas in an optical lattice, in the presence of a strong three-body constraint arising due to three-body loss. Using analytical and nu…
Dissipation-induced d-Wave Pairing of Fermionic Atoms in an Optical Lattice
S. Diehl, W. Yi, A. J. Daley +1
We show how dissipative dynamics can give rise to pairing for two-component fermions on a lattice. In particular, we construct a "parent" Liouvillian operator so that a BCS-type st…
Quantum Field Theory for the Three-Body Constrained Lattice Bose Gas -- Part II: Application to the Many-Body Problem
S. Diehl, M. Baranov, A. J. Daley +1
We analyze the ground state phase diagram of attractive lattice bosons, which are stabilized by a three-body onsite hardcore constraint. A salient feature of this model is an Ising…
Quantum Field Theory for the Three-Body Constrained Lattice Bose Gas -- Part I: Formal Developments
S. Diehl, M. Baranov, A. J. Daley +1
We develop a quantum field theoretical framework to analytically study the three-body constrained Bose-Hubbard model beyond mean field and non-interacting spin wave approximations.…
An atomic colour superfluid via three-body loss
A. Kantian, M. Dalmonte, S. Diehl +3
Large three-body losses in a three-component Fermi gas confined in an optical lattice can prevent the occupation of a lattice site by three atoms. This effective constraint not onl…
Functional renormalization group approach to the BCS-BEC crossover
S. Diehl, S. Floerchinger, H. Gies +2
The phase transition to superfluidity and the BCS-BEC crossover for an ultracold gas of fermionic atoms is discussed within a functional renormalization group approach. Non-perturb…
Stabilization of the p-wave superfluid state in an optical lattice
Y. -J. Han, Y. -H. Chan, W. Yi +4
It is hard to stabilize the p-wave superfluid state of cold atomic gas in free space due to inelastic collisional losses. We consider the p-wave Feshbach resonance in an optical la…
