Correlation-induced steady states and limit cycles in driven dissipative quantum systems
Haggai Landa, Marco Schiró, Grégoire Misguich
We study a driven-dissipative model of spins one-half (qubits) on a lattice with nearest-neighbor interactions. Focusing on the role of spatially extended spin-spin correlations in…
Nonlocal interferences induced by the phase of the wavefunction for a particle in a cavity with moving boundaries
Mordecai Waegell, Alex Matzkin
We investigate the dynamics of a particle in a confined periodic system---a time-dependent oscillator confined by infinitely high and moving walls---and focus on the evolution of t…
Multistability of Driven-Dissipative Quantum Spins
Haggai Landa, Marco Schiró, Grégoire Misguich
We study the dynamics of lattice models of quantum spins one-half, driven by a coherent drive and subject to dissipation. Generically the meanfield limit of these models manifests…
Weak values and quantum properties
A. Matzkin
We investigate in this work the meaning of weak values through the prism of property ascription in quantum systems. Indeed, the weak measurements framework contains only ingredient…
Nonlocality and local causality in the Schrödinger Equation with time-dependent boundary conditions
A. Matzkin, S. V. Mousavi, M. Waegell
We investigate the nonlocal dynamics of a single particle placed in an infinite well with moving walls. It is shown that in this situation, the Schrödinger equation (SE) violates l…
Reply to Comment on "Null weak values and the past of a quantum particle" by D. Sokolovski
Q. Duprey, A. Matzkin
We discuss the preceding Comment and conclude that the arguments given there against the relevance of null weak values as representing the absence of a system property are not comp…
Single particle nonlocality, geometric phases and time-dependent boundary conditions
A. Matzkin
We investigate the issue of single particle nonlocality in a quantum system subjected to time-dependent boundary conditions. We discuss earlier claims according to which the quantu…
The Quantum Cheshire Cat effect: Theoretical basis and observational implications
Q. Duprey, S. Kanjilal, Urbasi Sinha +2
The Quantum Cheshire Cat (QCC) is an effect introduced recently within the Weak Measurements framework. The main feature of the QCC effect is that a property of a quantum particle…
Entangling two atoms of different isotopes via Rydberg blockade
Y. Zeng, P. Xu, X. D. He +6
Quantum entanglement is crucial for simulating and understanding exotic physics of strongly correlated many-body systems, such as high--temperature superconductors, or fractional q…
General complex Spin Weak Values obtained in Matter-Wave Interferometer Experiments
Stephan Sponar, Tobias Denkmayr, Hermann Geppert +3
Weak values of the spin operator Sz of massive particles, more precisely neutrons, have been experimentally determined by applying a novel measurement scheme. This is achieved by c…
Quantum-elastic bump on a surface
Victor Atanasov, Rossen Dandoloff
We use an exact solution of the elastic membrane shape equation, representing the curvature, which will serve as a quantum potential in the quantum mechanical two dimensional Schro…
Observation of a quantum Cheshire Cat in a matter wave interferometer experiment
Tobias Denkmayr, Hermann Geppert, Stephan Sponar +4
From its very beginning quantum theory has been revealing extraordinary and counter-intuitive phenomena, such as wave-particle duality, Schrödinger cats and quantum non-locality. I…
Lamb shift of non-degenerate energy level systems placed between two infinite parallel conducting plates
B. Billaud, T. -T. Truong
The issue of the observability of the Lamb shift in systems with non-degenerate energy levels is put to question. To this end, we compute the Lamb shift of such systems in the elec…
Observing trajectories with weak measurements in quantum systems in the semiclassical regime
A. Matzkin
We propose a scheme allowing to observe the evolution of a quantum system in the semiclassical regime along the paths generated by the propagator. The scheme relies on performing c…
Entanglement, the quantum formalism and the classical world
Alex Matzkin
75 years after the term "entanglement" was coined to a peculiar feature inherent to quantum systems, the connection between quantum and classical mechanics remains an open problem.…
Weak and semiweak values in non-ideal spin measurements: an exact treatment beyond the asymptotic regime
A. K. Pan, A. Matzkin
We consider weak measurements (WM) of a spin observable in quantum mechanics beyond the usual asymptotic regime. This is done by obtaining the exact time-dependent wave functions o…
Entanglement in the classical limit: quantum correlations from classical probabilities
Alex Matzkin
We investigate entanglement for a composite closed system endowed with a scaling property allowing to keep the dynamics invariant while the effective Planck constant hbar_eff of th…
Quantum anticentrifugal potential in a bent waveguide
R. Dandoloff, V. Atanasov
We show the existence of an anticentrifugal force for a quantum particle in a bent waveguide. This counterintuitive force due to dimensionality was shown to exist in a flat s…
Larmor precession reexamined: Testable correction and its ramifications
Dipankar Home, Alok Kumar Pan, Arka Banerjee
For a spin-polarized plane wave passing through a spin-rotator containing uniform magnetic field, we provide a detailed analysis for solving the appropriate Schrödinger equation. A…
Geometry induced potential on a 2D-section of a wormhole: catenoid
Rossen Dandoloff, Avadh Saxena, Bjorn Jensen
We show that a two dimensional wormhole geometry is equivalent to a catenoid, a minimal surface. We then obtain the curvature induced geometric potential and show that the ground s…
State-independent quantum violation of noncontextuality in four dimensional space using five observables and two settings
Alok Kumar Pan, Dipankar Home
Recently, a striking experimental demonstration [G. Kirchmair \emph{et al.}, Nature, \textbf{460}, 494(2009)] of the state-independent quantum mechanical violation of non-contextua…
Quantum mechanics of a constrained electrically charged particle in the presence of electric currents
B. Jensen, R. Dandoloff
We discuss the dynamics of a classical spinless quantum particle carrying electric charge and constrained to move on a non singular static surface in ordinary three dimensional spa…
An interplay between nonlocality and quantum violation of path-spin noncontextuality
Dipankar Home, Alok Kumar Pan
In terms of a suitable variant of the EPR-Bohm example, we argue that the quantum mechanically predicted and experimentally verified violation of a Bell-type path-spin noncontextua…
Quantum anticentrifugal force for wormhole geometry
Rossen Dandoloff
We show the existence of an anticentrifugal force in a wormhole geometry in . This counterintuitive force was shown to exist in a flat space. The role the geometry plays…
