Absorbing State Phase Transition with Clifford Circuits
Nastasia Makki, Nicolai Lang, Hans Peter Büchler
The role of quantum fluctuations in modifying the critical behavior of non-equilibrium phase transitions is a fundamental but unsolved question. In this study, we examine the absor…
The Role of Quantum Fluctuations in the Hexatic Phase of Cold Polar Molecules
Wolfgang Lechner, Hans-Peter Büchler, Peter Zoller
Two dimensional crystals melt via an intermediate \textit{hexatic} phase which is characterized by an anomalous scaling of spatial and orientational correlation functions and the a…
Supersolid phase with cold polar molecules on a triangular lattice
L. Pollet, J. D. Picon, H. P. Buechler +1
We study a system of heteronuclear molecules on a triangular lattice and analyze the potential of this system for the experimental realization of a supersolid phase. The ground sta…
Three-body interactions with cold polar molecules
H. P. Büchler, A. Micheli, P. Zoller
We show that polar molecules driven by microwave fields give naturally rise to strong three-body interactions, while the two-particle interaction can be independently controlled an…
Strongly correlated 2D quantum phases with cold polar molecules: controlling the shape of the interaction potential
H. P. Büchler, E. Demler, M. Lukin +4
We discuss techniques to tune and shape the long-range part of the interaction potentials in quantum gases of polar molecules by dressing rotational excitations with static and mic…
Spectroscopy of Superfluid Pairing in Atomic Fermi Gases
H. P. Büchler, P. Zoller, W. Zwerger
We study the dynamic structure factor for density and spin within the crossover from BCS superfluidity of atomic fermions to the Bose-Einstein condensation of molecules. Both struc…
