Engineering nonequilibrium steady states through Floquet Liouvillians
Weijian Chen, Maryam Abbasi, Serra Erdamar +3
We experimentally study the transient dynamics of a dissipative superconducting qubit under periodic drive towards its nonequilibrium steady states. The corresponding stroboscopic…
Constraining work fluctuations of non-Hermitian dynamics across the exceptional point of a superconducting qubit
Serra Erdamar, Maryam Abbasi, Byung Ha +4
Thermodynamics constrains changes to the energy of a system, both deliberate and random, via its first and second laws. When the system is not in equilibrium, fluctuation theorems…
Observing super-quantum correlations across the exceptional point in a single, two-level trapped ion
Alexander Quinn, Jeremy Metzner, Jacob E. Muldoon +5
Quantum theory provides rules governing much of the microscopic world, and among its counter-intuitive consequences are correlations that exceed the bounds from local, classical th…
-Symmetry breaking in quantum spin chains with exceptional non-Hermiticities
Jacob Muldoon, Yogesh N. Joglekar
Since the realization of quantum systems described by non-Hermitian Hamiltonians with parity-time (PT) symmetry, interest in non-Hermitian, quantum many-body models has steadily gr…
Essential role of quantum speed limit in violation of Leggett-Garg inequality across a PT-transition
Anant V. Varma, Jacob E. Muldoon, Sourav Paul +2
We study Leggett-Garg inequality (LGI) of a two level system (TLS) undergoing non-Hermitian dynamics governed by a non-linear Bloch equation (derived in J. Phys. A: Math. Theor. 54…
Conserved quantities in non-Hermitian systems via vectorization method
Kaustubh S. Agarwal, Jacob Muldoon, Yogesh N. Joglekar
Open classical and quantum systems have attracted great interest in the past two decades. These include systems described by non-Hermitian Hamiltonians with parity-time $(\mathcal{…
Floquet exceptional contours in Lindblad dynamics with time-periodic drive and dissipation
John Gunderson, Jacob Muldoon, Kater W. Murch +1
The dynamics of an isolated quantum system is coherent and unitary. Weak coupling to the environment leads to decoherence, which is traditionally modeled with a Lindblad equation f…
