Controlling emergent dynamical behavior via phase-engineered strong symmetries
Marc Nairn, Beatriz Olmos, Parvinder Solanki
Symmetry constraints provide a powerful means to control the dynamics of open quantum systems. However, the set of accessible control parameters is often limited. Here, we show tha…
Hierarchical time crystals
Jan Carlo Schumann, Igor Lesanovsky, Parvinder Solanki
Spontaneous symmetry breaking is one of the central organizing principles in physics. Time crystals have emerged as an exotic phase of matter, spontaneously breaking the time trans…
Universal relaxation speedup in open quantum systems through transient conditional and unconditional resetting
Parvinder Solanki, Igor Lesanovsky, Gabriele Perfetto
Speeding up the relaxation dynamics of many-body quantum systems is important in a variety of contexts, including quantum computation and state preparation. We demonstrate that suc…
Quantum Synchronization of Twin Limit-Cycle Oscillators
Tobias Kehrer, Christoph Bruder, Parvinder Solanki
Quantum synchronization has been a subject of intensive research in the last decade. In this work, we propose a quantum Liénard system whose classical equivalent features two limi…
Generation of entanglement and non-stationary states via competing coherent and incoherent bosonic hopping
Parvinder Solanki, Albert Cabot, Matteo Brunelli +3
Incoherent stochastic processes added to unitary dynamics are typically deemed detrimental since they are expected to diminish quantum features such as superposition and entangleme…
Chaos in Time: A Dissipative Continuous Quasi Time Crystals
Parvinder Solanki, Fabrizio Minganti
While a generic open quantum system decays to its steady state, continuous time crystals (CTCs) develop spontaneous oscillation and never converge to a stationary state. Just as cr…
