Emergent XY* transition driven by symmetry fractionalization and anyon condensation
Michael Schuler, Louis-Paul Henry, Yuan-Ming Lu +1
Anyons in a topologically ordered phase can carry fractional quantum numbers with respect to the symmetry group of the considered system, one example being the fractional charge of…
Comment on "The role of electron-electron interactions in two-dimensional Dirac fermions''
Stephan Hesselmann, Thomas C. Lang, Michael Schuler +2
Tang et al. [Science 361, 570 (2018)] report on the properties of Dirac fermions with both on-site and Coulomb interactions. The substantial decrease up to ~40% of the Fermi veloci…
Torus Spectroscopy of the Gross-Neveu-Yukawa Quantum Field Theory: Free Dirac versus Chiral Ising Fixed Point
Michael Schuler, Stephan Hesselmann, Seth Whitsitt +3
We establish the universal torus low-energy spectra at the free Dirac fixed point and at the strongly coupled chiral Ising fixed point and their subtle crossover behaviour in the G…
Adiabatic Preparation of a Correlated Symmetry-Broken Initial State with the Generalized Kadanoff--Baym Ansatz
Riku Tuovinen, Denis Golež, Michael Schüler +3
A fast time propagation method for nonequilibrium Green's functions based on the generalized Kadanoff--Baym Ansatz (GKBA) is applied to a lattice system with a symmetry-broken equi…
Truncating the memory time in nonequilibrium DMFT calculations
Michael Schüler, Martin Eckstein, Philipp Werner
The nonequilibrium Green's functions (NEGF) approach is a versatile theoretical tool, which allows to describe the electronic structure, spectroscopy and dynamics of strongly corre…
Studying Continuous Symmetry Breaking using Energy Level Spectroscopy
Alexander Wietek, Michael Schuler, Andreas M. Läuchli
Tower of States analysis is a powerful tool for investigating phase transitions in condensed matter systems. Spontaneous symmetry breaking implies a specific structure of the energ…
Spectrum of the Wilson-Fisher conformal field theory on the torus
Seth Whitsitt, Michael Schuler, Louis-Paul Henry +2
We study the finite-size spectrum of the O() symmetric Wilson-Fisher conformal field theory (CFT) on the spatial-dimension torus using the expansion in . This is do…
Universal Signatures of Quantum Critical Points from Finite-Size Torus Spectra: A Window into the Operator Content of Higher-Dimensional Conformal Field Theories
Michael Schuler, Seth Whitsitt, Louis-Paul Henry +2
The low-energy spectra of many body systems on a torus, of finite size , are well understood in magnetically ordered and gapped topological phases. However, the spectra at quant…
Single and double electron emission: combination of projection operator and nonequilibrium Green's function approaches
Y. Pavlyukh, M. Schüler, J. Berakdar
This work provides a unified theoretical treatment of the single and correlated double-electron emission from a general electronic system. Using Feshbach projection method, the sta…
