Zeroth Law in Quantum Thermodynamics at Strong Coupling: `in Equilibrium', not `Equal Temperature'
Jen-Tsung Hsiang, Bei-Lok Hu
The zeroth law of thermodynamics involves a transitivity relation (pairwise between three objects) expressed either in terms of `equal temperature' (ET), or `in equilibrium' (EQ) c…
Temperature Dependent Energy Diffusion in Chaotic Spin Chains
Cristian Zanoci, Brian Swingle
We study the temperature dependence of energy diffusion in two chaotic gapped quantum spin chains, a tilted-field Ising model and an XZ model, using an open system approach. We int…
Programmable Quantum Annealers as Noisy Gibbs Samplers
Marc Vuffray, Carleton Coffrin, Yaroslav A. Kharkov +1
Drawing independent samples from high-dimensional probability distributions represents the major computational bottleneck for modern algorithms, including powerful machine learning…
Quantum teleportation and entanglement swapping with long baseline in outer space
Shih-Yuin Lin, B. L. Hu
Quantum information experiments applying quantum optics in outer space with a very long baseline may have advantages over the current earth-bound experiments or the earth-to-satell…
Nonequilibrium Quantum Free Energy and Effective Temperature, Generating Functional and Influence Action
Jen-Tsung Hsiang, B. L. Hu
A definition of nonequilibrium free energy $\mathcal{F}_{\textsc{s}}$ is proposed for dynamical Gaussian quantum open systems strongly coupled to a heat bath and a formal derivatio…
Energy storage and coherence in closed and open quantum batteries
Francesco Caravelli, Bin Yan, Luis Pedro Garcia-Pintos +1
We study the role of coherence in closed and open quantum batteries. We obtain upper bounds to the work performed or energy exchanged by both closed and open quantum batteries in t…
Intrinsic Time-reversal-invariant Topological Superconductivity in Thin Films of Iron-based Superconductors
Rui-Xing Zhang, S. Das Sarma
We establish quasi-two-dimensional thin films of iron-based superconductors (FeSCs) as a new high-temperature platform for hosting intrinsic time-reversal-invariant helical topolog…
Disorder effects on Majorana zero modes: Kitaev chain versus semiconductor nanowire
Haining Pan, S. Das Sarma
Majorana zero modes in a superconductor-semiconductor nanowire have been extensively studied during the past decade. Disorder remains a serious problem, preventing the definitive o…
Exact analytical treatment of multiqubit noisy dynamics in exchange-coupled semiconductor spin qubits
Donovan Buterakos, Sankar Das Sarma
Charge noise remains the primary obstacle to the development of quantum information technologies with semiconductor spin qubits. We use an exact analytical calculation to determine…
Hydrodynamic sound and plasmons in three dimensions
Shao-Kai Jian, Sankar Das Sarma
In a recent paper by Lucas and Das Sarma [Physical Review B 97, 115449 (2018)], a solvable model of collective modes in 2D metals was considered in the hydrodynamic regime. In the…
Interaction-Driven Filling-Induced Metal-Insulator Transitions in 2D Moiré Lattices
Haining Pan, Sankar Das Sarma
Using a realistic band structure for twisted WSe materials, we develop a theory for the interaction-driven correlated insulators to conducting metals transitions through the t…
Localization and criticality in antiblockaded 2D Rydberg atom arrays
Fangli Liu, Zhi-Cheng Yang, Przemyslaw Bienias +2
Controllable Rydberg atom arrays have provided new insights into fundamental properties of quantum matter both in and out of equilibrium. In this work, we study the effect of exper…
Coherence and decoherence in the Harper-Hofstadter model
Qi-Yu Liang, Dimitris Trypogeorgos, Ana Valdés-Curiel +3
We quantum-simulated the 2D Harper-Hofstadter (HH) lattice model in a highly elongated tube geometry -- three sites in circumference -- using an atomic Bose-Einstein condensate. In…
