Neutron spin echo is a "quantum tale of two paths''
S. McKay, A. A. M. Irfan, Q. Le Thien +7
We describe an experiment that strongly supports a two-path interferometric model in which the spin-up and spin-down components of each neutron propagate coherently along spatially…
Fusion mechanism for quasiparticles and topological quantum order in the lowest Landau level
Arkadiusz Bochniak, Gerardo Ortiz
Starting from Halperin multilayer systems we develop a hierarchical scheme that generates, bosonic and fermionic, single-layer quantum Hall states (or vacua) of arbitrary filling f…
Universal fragility of spin-glass ground-states under single bond changes
Mutian Shen, Gerardo Ortiz, Yang-Yu Liu +2
We consider the effect of perturbing a single bond on ground-states of nearest-neighbor Ising spin-glasses, with a Gaussian distribution of the coupling constants, across various t…
Wiener-Hopf factorization approach to a bulk-boundary correspondence and stability conditions for topological zero-energy modes
Abhijeet Alase, Emilio Cobanera, Gerardo Ortiz +1
Both the physics and applications of fermionic symmetry-protected topological phases rely heavily on a principle known as bulk-boundary correspondence, which predicts the emergence…
Quasicriticality explains variability of human neural dynamics across life span
L. J. Fosque, A. Alipour, M. Zare +3
Ageing impacts the brain's structural and functional organization and over time leads to various disorders, such as Alzheimer's disease and cognitive impairment. The process also i…
A Theorem on Extensive Spectral Degeneracy for Systems with Higher Symmetries in General Dimensions
Zohar Nussinov, Gerardo Ortiz
We establish, in the spirit of the Lieb-Schultz-Mattis theorem, lower bounds on the spectral degeneracy of quantum systems with higher (Gauge Like) symmetries with rather generic p…
