Quantum circuit algorithm for topological invariants of second order topological many-body quantum magnets
Sebastián Domínguez-Calderón, Marcel Niedermeier, Jose L. Lado +1
Topological quantum matter represents a flexible playground to engineer unconventional excitations. While non-interacting topological single-particle systems have been studied in d…
How can a geothermal storage system be optimally integrated into a local district? A case study
Ueli Schilt, Somesh Vijayananda, Sarah Schneeberger +4
Achieving net-zero targets requires the phase-out of fossil-based heating. A major challenge is the seasonal mismatch between renewable heat supply and demand. District heating net…
Lee-Yang formalism for phase transitions of interacting fermions using tensor networks
Pascal M. Vecsei, Jose L. Lado, Christian Flindt
Predicting the phase diagram of interacting quantum many-body systems is a challenging problem in condensed matter physics. Strong interactions and correlation effects may lead to…
Phase diagram of the J1-J2 Heisenberg second-order topological quantum magnet
Pascal M. Vecsei, Jose L. Lado
Competing interactions in quantum magnets lead to a variety of emergent states, including ordered phases, nematic magnets and quantum spin liquids. Among them, topological quantum…
Lee-Yang theory of quantum phase transitions with neural network quantum states
Pascal M. Vecsei, Christian Flindt, Jose L. Lado
Predicting the phase diagram of interacting quantum many-body systems is a central problem in condensed matter physics and related fields. A variety of quantum many-body systems, r…
Lee-Yang theory of the two-dimensional quantum Ising model
Pascal M. Vecsei, Jose L. Lado, Christian Flindt
Determining the phase diagram of interacting quantum many-body systems is an important task for a wide range of problems such as the understanding and design of quantum materials.…
Symmetry Indicators for Inversion-Symmetric Non-Hermitian Topological Band Structures
Pascal M. Vecsei, M. Michael Denner, Titus Neupert +1
We characterize non-Hermitian band structures by symmetry indicator topological invariants. Enabled by crystalline inversion symmetry, these indicators allow us to short-cut the ca…
Neural Network-based Classification of Crystal Symmetries from X-Ray Diffraction Patterns
Pascal Marc Vecsei, Kenny Choo, Johan Chang +1
Machine learning algorithms based on artificial neural networks have proven very useful for a variety of classification problems. Here we apply them to a well-known problem in crys…
