An Atlas of Classical Pyrochlore Spin Liquids
Daniel Lozano-Gómez, Owen Benton, Michel J. P. Gingras +1
Frustrated magnetism in the pyrochlore lattice magnet has proven to be a most fruitful setting for the experimental and theoretical search for spin liquids. Besides the canonical c…
Higher-Rank Spin Liquids and Spin Nematics from Competing Orders in Pyrochlore Magnets
Niccolò Francini, Lukas Janssen, Daniel Lozano-Gómez
Pyrochlore magnets have proven to provide an excellent arena for the realization of a variety of many-body phenomena such as classical and quantum order-by-disorder, as well as spi…
A Classical Chiral Spin-Liquid from Chiral Interactions on the Pyrochlore Lattice
Daniel Lozano-Gómez, Yasir Iqbal, Matthias Vojta
Classical spin-liquids are paramagnetic phases which feature nontrivial patterns of spin correlations within their ground-state manifold whose degeneracy scales with system size. O…
Order-by-disorder without quantum zero-point fluctuations in the pyrochlore Heisenberg ferromagnet with Dzyaloshinskii-Moriya interactions
Alexander Hickey, Daniel Lozano-Gómez, Michel J. P. Gingras
Order-by-disorder, whereby fluctuations lift an accidental classical ground state degeneracy to stabilize a subset of ordered states, is a recurrent and prominent theme in the fiel…
Competing Gauge Fields and Entropically-Driven Spin Liquid to Spin Liquid Transition in non-Kramers Pyrochlores
Daniel Lozano-Gómez, Vincent Noculak, Jaan Oitmaa +4
Gauge theories are powerful tools in theoretical physics, allowing complex phenomena to be reduced to simple principles, and are used in both high-energy and condensed matter physi…
Classical and quantum phases of the pyrochlore magnet with Heisenberg and Dzyaloshinskii-Moriya interactions
Vincent Noculak, Daniel Lozano-Gómez, Jaan Oitmaa +4
We investigate the ground state and critical temperature phase diagrams of the classical and quantum pyrochlore lattice with nearest-neighbor Heisenberg and Dzyaloshinskii-…
Probing Flat Band Physics in Spin Ice Systems via Polarized Neutron Scattering
Kristian Tyn Kai Chung, Jeremy Swee Kang Goh, Aritro Mukherjee +3
In this paper, we illustrate how polarized neutron scattering can be used to isolate the spin-spin correlations of modes forming flat bands in a frustrated magnetic system hosting…
Quantum Tunneling Theory of Cooper Pairs as Bosonic Particles
Edgar J. Patiño, Daniel Lozano-Gómez
We propose a simple phenomenological theory for quantum tunneling of Cooper pairs based on their boson like nature. Thus it applies in the absence of quasiparticle excitations (fer…
Electron interaction with the environment in tunnel ionization
D. Lozano-Gómez, N. G. Kelkar
The average dwell time of an electron in a potential barrier formed by an external electric field and the potential of a helium atom is evaluated within a semi classical one-dimens…
Unsupervised Machine Learning of Quenched Gauge Symmetries: A Proof-of-Concept Demonstration
Daniel Lozano-Gómez, Darren Pereira, Michel J. P. Gingras
In condensed matter physics, one of the goals of machine learning is the classification of phases of matter. The consideration of a system's symmetries can significantly assist the…
Time in dissipative tunneling: subtleties and applications
N. G. Kelkar, D. Lozano Gómez, Edgar J. Patiño
Characteristic features of tunneling times for dissipative tunneling of a particle through a rectangular barrier are studied within a semiclassical model involving dissipation in t…
