Topology and energy dependence of Majorana bound states in a photonic cavity

Aksel Kobiałka, Arnob Kumar Ghosh, Rodrigo Arouca +1

Light-matter interaction plays a crucial role in modifying the properties of quantum materials. In this work, we investigate the effect of cavity induced photon fields on a topolog…

On the relation between fractional charge and statistics

T. H. Hansson, Rodrigo Arouca, Thomas Klein Kvorning

We revisit an argument, originally given by Kivelson and Roček, for why the existence of fractional charge necessarily implies fractional statistics. In doing so, we resolve a cont…

Local and energy-resolved topological invariants for Floquet systems

Arnob Kumar Ghosh, Rodrigo Arouca, Annica M. Black-Schaffer

Periodically driven systems offer a perfect breeding ground for out-of-equilibrium engineering of topological boundary states at zero energy (-mode), as well as finite energy ($…

Mixed higher-order topology and nodal and nodeless flat band topological phases in a superconducting multiorbital model

Rodrigo Arouca, Tanay Nag, Annica M. Black-Schaffer

We investigate the topological phases that appear in an orbital version of the Benalcazar-Bernevig-Hughes (BBH) model in the presence of conventional spin-singlet -wave supercon…

Topological edge and corner states in Bi fractals on InSb

R. Canyellas, Chen Liu, R. Arouca +10

Topological materials hosting metallic edges characterized by integer quantized conductivity in an insulating bulk have revolutionized our understanding of transport in matter. The…

Breaking and resurgence of symmetry in the non-Hermitian Su-Schrieffer-Heeger model in photonic waveguides

E. Slootman, W. Cherifi, L. Eek +4

Symmetry is one of the cornerstones of modern physics and has profound implications in different areas. In symmetry-protected topological systems, symmetries are responsible for pr…

Topological superconductivity enhanced by exceptional points

R. Arouca, Jorge Cayao, Annica M. Black-Schaffer

Majorana zero modes (MZMs) emerge as edge states in topological superconductors and are promising for topological quantum computation, but their detection has so far been elusive.…

Non-Hermitian quantum gases: a platform for imaginary time crystals

R. Arouca, E. C. Marino, C. Morais Smith

One of the most important applications of quantum mechanics is the thermodynamic description of quantum gases. Despite the fundamental importance of this topic, a comprehensive des…

Magnetic Field Effects on the Transport Properties of High-Tc Cuprates

E. C. Marino, R. Arouca

Starting from a recently proposed comprehensive theory for the high-Tc superconductivity in cuprates, we derive a general analytic expression for the planar resistivity, in the pre…

Unconventional scaling at non-Hermitian critical points

R. Arouca, C. H. Lee, C. Morais Smith

Critical phase transitions contain a variety of deep and universal physics, and are intimately tied to thermodynamic quantities through scaling relations. Yet, these notions are ch…

The Resistivity of High-Tc Cuprates

R. Arouca, E. C. Marino

We show that the resistivity in each phase of the High-Tc cuprates is a special case of a general expression derived from the Kubo formula. We obtain, in particular, the T-linear b…

Thermodynamics of a Higher-Order Topological Insulator

R. Arouca, S. N. Kempkes, C. Morais Smith

We investigate the order of the topological quantum phase transition in a two dimensional quadrupolar topological insulator within a thermodynamic approach. Using numerical methods…
