The intersection numbers of the p-spin curves from random matrix theory
E. Brezin, S. Hikami
The intersection numbers of p-spin curves are computed through correlation functions of Gaussian ensembles of random matrices in an external matrix source. The p-dependence of inte…
Disorder induced localization and enhancement of entanglement in one- and two-dimensional quantum walks
C. M. Chandrashekar
The time evolution of one- and two-dimensional discrete-time quantum walk with increase in disorder is studied. We use spatial, temporal and spatio-temporal broken periodicity of t…
Orthogonality catastrophe and decoherence in a trapped-Fermion environment
A. Sindona, J. Goold, N. Lo Gullo +2
The Fermi edge singularity and the Anderson orthogonality catastrophe describe the universal physics which occurs when a Fermi sea is locally quenched by the sudden switching of a…
Slender-body theory for viscous flow via dimensional reduction and hyperviscous regularization
Giulio G. Giusteri, Eliot Fried
A new slender-body theory for viscous flow, based on the concepts of dimensional reduction and hyperviscous regularization, is presented. The geometry of flat, elongated, or point-…
Noise-enhanced quantum transport on a closed loop using quantum walks
C. M. Chandrashekar, Th. Busch
We study the effect of noise on the transport of a quantum state from a closed loop of sites with one of the sites as a sink. Using a discrete-time quantum walk dynamics, we de…
Decoherence-assisted transport and quantum criticalities
Gian Luca Giorgi, Thomas Busch
We study the dynamics of a two-level quantum system interacting with an external environment that takes the form of an XY spin chain in the presence of an external magnetic field.…
Quantum gas mixtures in different correlation regimes
Miguel Angel Garcia-March, Thomas Busch
We present a many-body description for two-component ultracold bosonic gases when one of the species is in the weakly interacting regime and the other is either weakly or strongly…
Enhancement of Geometric Phase by Frustration of Decoherence: A Parrondo like Effect
Subhashish Banerjee, C. M. Chandrashekar, Arun K. Pati
Geometric phase plays an important role in evolution of pure or mixed quantum states. However, when a system undergoes decoherence the development of geometric phase may be inhibit…
Observation of Zeeman shift in the rubidium D2 line using an optical nanofiber in vapor
Amy Watkins, Vibhuti Bhushan Tiwari, Jonathan M. Ward +1
We report on the observation of a Zeeman shift (order of 100 MHz) of the Doppler-broadened D2 transition of both 85Rb and 87Rb isotopes via transmission through a tapered optical n…
Entangling two defects via a surrounding crystal
Thomás Fogarty, Endre Kajari, Bruno G. Taketani +3
We theoretically show how two impurity defects in a crystalline structure can be entangled through coupling with the crystal. We demonstrate this with a harmonic chain of trapped i…
Predominance of entanglement of formation over quantum discord under quantum channels
Steve Campbell
We present a study of the behavior of two different figures of merit for quantum correlations, entanglement of formation and quantum discord, under quantum channels showing how the…
Complex synchronous behavior in interneuronal networks with delayed inhibitory and fast electrical synapses
Daqing Guo, Qingyun Wang, Matjaz Perc
Networks of fast-spiking interneurons are crucial for the generation of neural oscillations in the brain. Here we study the synchronous behavior of interneuronal networks that are…
Genuine correlations in finite-size spin systems
Gian Luca Giorgi, Thomas Busch
Genuine multipartite correlations in finite-size XY chains are studied as a function of the applied external magnetic field. We find that, for low temperatures, multipartite correl…
Topological Sector Fluctuations and Curie Law Crossover in Spin Ice
Ludovic D. C. Jaubert, Mark J. Harris, Tom Fennell +3
At low temperatures, a spin ice enters a Coulomb phase - a state with algebraic correlations and topologically constrained spin configurations. In Ho2Ti2O7, we have observed experi…
Seeing the light : experimental signatures of emergent electromagnetism in a quantum spin ice
Owen Benton, Olga Sikora, Nic Shannon
The "spin ice" state found in the rare earth pyrochlore magnets Ho2Ti2O7 and Dy2Ti2O7 offers a beautiful realisation of classical magnetostatics, complete with magnetic monopole ex…
Decoherence on a two-dimensional quantum walk using four- and two-state particle
C. M. Chandrashekar, Th. Busch
We study the decoherence effects originating from state flipping and depolarization for two-dimensional discrete-time quantum walks using four-state and two-state particles. By qua…
Critical assessment of two-qubit post-Markovian master equations
S. Campbell, A. Smirne, L. Mazzola +4
A post-Markovian master equation has been recently proposed as a tool to describe the evolution of a system coupled to a memory-keeping environment [A. Shabani and D. A. Lidar, Phy…
Thermo-Optical Tuning of Whispering Gallery Modes in Er:Yb Doped Glass Microspheres to Arbitrary Probe Wavelengths
Amy Watkins, Jonathan Ward, Síle Nic Chormaic
We present experimental results on an all-optical, thermally-assisted technique for broad range tuning of microsphere cavity resonance modes to arbitrary probe wavelengths. An Er:Y…
Derivation Lengths Classification of Gödel's T Extending Howard's Assignment
Gunnar Wilken, Andreas Weiermann
Let T be Goedel's system of primitive recursive functionals of finite type in the lambda formulation. We define by constructive means using recursion on nested multisets a multival…
Bistability and Hysteresis of Intersubband Absorption in Strongly Interacting Electrons on Liquid Helium
Denis Konstantinov, M. I. Dykman, M. J. Lea +2
We study nonlinear inter-subband microwave absorption of electrons bound to the liquid helium surface. Already for a comparatively low radiation intensity, resonant absorption due…
