Discrete holography and density of states in the crossover from hyperbolic to Euclidean lattices
Mireia Tolosa-Simeón, Igor Boettcher
We study tight-binding models in the crossover from hyperbolic to Euclidean lattices, realized through the successive insertion of Euclidean defects into hyperbolic lattices. We an…
A simple quantum dot: numerical and variational solutions
Connor Walsh, Ian MacPherson, Davidson Joseph +4
We describe a simple quantum dot that consists of two crossed two-dimensional troughs. As such there is no potential well; nonetheless, this geometry gives rise to a bound state, c…
Spin Dependence of Charge Dynamics and Group Velocity in Chiral Molecules
Riley Stuermer, Collin VanEssen, Jacob Byers +5
Chiral molecules are known to preferentially select electrons with a particular spin state, an effect termed chirality-induced spin selectivity (CISS). In this work, the transient…
Dimensional crossover of superfluid He in a magnetic field
Leyla Saraj, Daksh Malhotra, Aymar Muhikira +3
Motivated by recent experiments on superfluid He in nanoscale-confined geometries, we theoretically investigate the associated phase diagram in a slab geometry and perpendicula…
Dynamical Confinement and Magnetic Traps for Charges and Spins
Afshin Besharat, Alexander A. Penin
We use the effective field theory approach to systematically study the dynamics of classical and quantum systems in an oscillating magnetic field. We find that the fast field oscil…
Isotopic separation in mixed clusters of molecular hydrogen
Kiril M. Kolevski, Jie-Ru Hu, Massimo Boninsegni
We investigate mixed (50/50) clusters of parahydrogen and orthodeuterium at low temperature, by means of Quantum Monte Carlo simulations. Our results provide evidence of liquid-lik…
Topological linear response of hyperbolic Chern insulators
Canon Sun, Anffany Chen, Tomáš Bzdušek +1
We establish a connection between the electromagnetic Hall response and band topological invariants in hyperbolic Chern insulators by deriving a hyperbolic analog of the Thouless-K…
Simulating Holographic Conformal Field Theories on Hyperbolic Lattices
Santanu Dey, Anffany Chen, Pablo Basteiro +10
We demonstrate how table-top settings combining hyperbolic lattices with nonlinear dynamics universally encode aspects of the bulk-boundary-correspondence between gravity in anti-d…
Magnon-microwave backaction noise evasion in cavity magnomechanics
V. A. S. V. Bittencourt, C. A. Potts, J. P. Davis +1
In cavity magnomechanical systems, magnetic excitations couple simultaneously with mechanical vibrations and microwaves, incorporating the tunability of magnetism and the long life…
Hyperbolic lattices and two-dimensional Yang-Mills theory
G. Shankar, Joseph Maciejko
Hyperbolic lattices are a new type of synthetic quantum matter emulated in circuit quantum electrodynamics and electric-circuit networks, where particles coherently hop on a discre…
Hyperbolic non-Abelian semimetal
Tarun Tummuru, Anffany Chen, Patrick M. Lenggenhager +3
We extend the notion of topologically protected semi-metallic band crossings to hyperbolic lattices in a negatively curved plane. Because of their distinct translation group struct…
Non-Abelian hyperbolic band theory from supercells
Patrick M. Lenggenhager, Joseph Maciejko, Tomáš Bzdušek
Wave functions on periodic lattices are commonly described by Bloch band theory. Besides Abelian Bloch states labeled by a momentum vector, hyperbolic lattices support non-Abelian…
Symmetry and topology of hyperbolic Haldane models
Anffany Chen, Yifei Guan, Patrick M. Lenggenhager +3
Particles hopping on a two-dimensional hyperbolic lattice feature unconventional energy spectra and wave functions that provide a largely uncharted platform for topological phases…
Magnomechanical backaction corrections due to coupling to higher order Walker modes and Kerr nonlinearities
V. A. S. V. Bittencourt, C. A. Potts, Y. Huang +2
The radiation pressure-like coupling between magnons and phonons in magnets can modify the phonon frequency (magnomechanical spring effect) and decay rate (magnomechanical decay) v…
Sublattice-enriched tunability of bound states in second-order topological insulators and superconductors
Di Zhu, Majid Kheirkhah, Zhongbo Yan
Bound states at sharp corners have been widely viewed as the hallmark of two-dimensional second-order topological insulators and superconductors. In this work, we show that the exi…

Logan Gates, Alexander A. Penin
We study Majorana zero modes bound to giant vortices in topological superconductors or topological insulator/normal superconductor heterostructures. By expanding in inverse powers…
Flat bands and band touching from real-space topology in hyperbolic lattices
Tomáš Bzdušek, Joseph Maciejko
Motivated by the recent experimental realizations of hyperbolic lattices in circuit quantum electrodynamics and in classical electric-circuit networks, we study flat bands and band…

Curved spaces play a fundamental role in many areas of modern physics, from cosmological length scales to subatomic structures related to quantum information and quantum gravity. I…
Hyperbolic Topological Band Insulators
David M. Urwyler, Patrick M. Lenggenhager, Igor Boettcher +3
Recently, hyperbolic lattices that tile the negatively curved hyperbolic plane emerged as a new paradigm of synthetic matter, and their energy levels were characterized by a band s…
