Statistical Floquet prethermalization of the Bose-Hubbard model
Emanuele G. Dalla Torre, David Dentelski
The manipulation of many-body systems often involves time-dependent forces that cause unwanted heating. One strategy to suppress heating is to use time-periodic (Floquet) forces at…
Many-body exceptional points in colliding condensates
Mati Aharonyan, Emanuele G. Dalla Torre
Exceptional points describe the coalescence of the eigenmodes of a non-Hermitian matrix. When an exceptional point occurs in the unitary evolution of a many-body system, it generic…
Spin and topological order in a periodically driven spin chain
Angelo Russomanno, Bat-el Friedman, Emanuele G. Dalla Torre
The periodically driven quantum Ising chain has recently attracted a large attention in the context of Floquet engineering. In addition to the common paramagnet and ferromagnet, th…
Quantum heat waves in a one-dimensional condensate
Kartiek Agarwal, Emanuele G. Dalla Torre, Jörg Schmiedmayer +1
We study the dynamics of phase relaxation between a pair of one-dimensional condensates created by a bi-directional, supersonic `unzipping' of a finite single condensate. We find t…
Non equilibrium phase transitions and Floquet Kibble-Zurek scaling
Angelo Russomanno, Emanuele G. Dalla Torre
We study the slow crossing of non-equilibrium quantum phase transitions in periodically-driven systems. We explicitly consider a spin chain with a uniform time-dependent magnetic f…
Quantum correlations and entanglement in far-from-equilibrium spin systems
Kaden R. A. Hazzard, Mauritz van den Worm, Michael Foss-Feig +5
By applying complementary analytic and numerical methods, we investigate the dynamics of spin- XXZ models with variable-range interactions in arbitrary dimensions. The dynamic…
Unstable Avoided Crossing in Coupled Spinor Condensates
Nathan R. Bernier, Emanuele G. Dalla Torre, Eugene Demler
We consider the dynamics of a Bose-Einstein condensate with two internal states, coupled through a coherent drive. We focus on a specific quench protocol, in which the sign of the…
Chiral Prethermalization in supersonically split condensates
Kartiek Agarwal, Emanuele G. Dalla Torre, Bernhard Rauer +3
We study the dynamics of phase relaxation between a pair of one-dimensional condensates created by a supersonic unzipping of a single condensate. We use the Lorentz invariance of t…
Universal Rephasing Dynamics after a Quantum Quench via Sudden Coupling of Two Initially Independent Condensates
Emanuele G. Dalla Torre, Eugene Demler, Anatoli Polkovnikov
We consider a quantum quench in which two initially independent condensates are suddenly coupled, and study the subsequent "rephasing" dynamics. For weak couplings, the time-evolut…
Noisy quantum phase transitions: an intuitive approach
Emanuele G. Dalla Torre, Eugene Demler, Thierry Giamarchi +1
Equilibrium thermal noise is known to destroy any quantum phase transition. What are the effects of non-equilibrium noise? In two recent papers we have considered the specific case…
Non-local Order in Elongated Dipolar Gases
Jonathan Ruhman, Emanuele G. Dalla Torre, Sebastian D. Huber +1
Dipolar particles in an elongated trap are expected to undergo a quantum phase transition from a linear to a zigzag structure with decreasing transverse confinement. We derive the…
Dynamics and universality in noise driven dissipative systems
Emanuele G. Dalla Torre, Eugene Demler, Thierry Giamarchi +1
We investigate the dynamical properties of low dimensional systems, driven by external noise sources. Specifically we consider a resistively shunted Josephson junction and a one di…
