Cloud on-demand emulation of quantum dynamics with tensor networks
Kemal Bidzhiev, Aleksander Wennersteen, Mourad Beji +6
We introduce a tensor network based emulator, simulating a programmable analog quantum processing unit (QPU). The software package is fully integrated in a cloud platform providing…
On the tension between growth rate and CMB data
Alba Quelle, Antonio L. Maroto
We analyze the claimed tension between redshift space distorsions measurements of and the predictions of standard CDM (Planck 2015 and 2018) cosmology. We consider…
Genesis of the Floquet Hofstadter butterfly
S. H. Kooi, A. Quelle, W. Beugeling +1
We investigate theoretically the spectrum of a graphene-like sample (honeycomb lattice) subjected to a perpendicular magnetic field and irradiated by circularly polarized light. Th…
Critical Behavior of Topological Kondo Insulators
J. J. van den Broeke, S. N. Kempkes, A. Quelle +1
A thermodynamic study of the Kondo insulator SmB is pursued to elucidate the well-known anomalous low-temperature electronic-like specific heat contribution conjectured to aris…
Resonances in a periodically driven bosonic system
Anton Quelle, Cristiane Morais Smith
Periodically driven systems are a common topic in modern physics. In optical lattices specifically, driving is at the origin of many interesting phenomena. However, energy is not c…
Staircase to Higher-Order Topological Phase Transitions
P. Cats, A. Quelle, O. Viyuela +2
We find a series of topological phase transitions of increasing order, beyond the more standard second-order phase transition in a one-dimensional topological superconductor. The j…
Proposed Spontaneous Generation of Magnetic Fields by Curved Layers of a Chiral Superconductor
T. Kvorning, T. H. Hansson, A. Quelle +1
We demonstrate that two-dimensional chiral superconductors on curved surfaces spontaneously develop magnetic flux. This geometric Meissner effect provides an unequivocal signature…
Driving protocol for a Floquet topological phase without static counterpart
A. Quelle, C. Weitenberg, K. Sengstock +1
Periodically driven systems play a prominent role in optical lattices. In these ultracold atomic systems, driving is used to create a variety of interesting behaviours, of which an…
Universalities of thermodynamic signatures in topological phases
S. N. Kempkes, A. Quelle, C. Morais Smith
Topological insulators (superconductors) are materials that host symmetry-protected metallic edge states in an insulating (superconducting) bulk. Although they are well understood,…
Edge Majoranas on locally flat surfaces - the cone and the Möbius band
A. Quelle, T. Kvorning, T. H. Hansson +1
In this paper, we investigate the edge Majorana modes in the simplest possible superconductor defined on surfaces with different geometry - the annulus, the cylind…
Bandwidth-resonant Floquet states in honeycomb optical lattices
Anton Quelle, Mark Goerbig, Cristiane Morais Smith
We investigate, within Floquet theory, topological phases in the out-of-equilibrium system that consists of fermions in a circularly shaken honeycomb optical lattice. We concentrat…
Topological Floquet states on a Möbius band irradiated by circularly polarised light
A. Quelle, W. Beugeling, C. Morais Smith
Topological states of matter in equilibrium, as well as out of equilibrium, have been thoroughly investigated during the last years in condensed-matter and cold-atom systems. Howev…
Dynamical competition between Quantum Hall and Quantum Spin Hall effects
Anton Quelle, Cristiane Morais Smith
In this paper we investigate the occurrence of quantum phase transitions in topological systems out of equi- librium. More specifically, we consider graphene with a sizable spin-or…
Nontrivial topological states on a Möbius band
W. Beugeling, A. Quelle, C. Morais Smith
In the field of topological insulators, the topological properties of quantum states in samples with simple geometries, such as a cylinder or a ribbon, have been classified and und…
