Vor einem Tag · When a system is driven across a continuous phase transition, the density of topological defects demonstrates a power-law scaling behavior versus the quenching rate, as predicted by the Kibble-Zurek mechanism. In this study, we generalize this idea and address the scaling of quantum state transport in a one-dimensional topological system subject to a linear drive through its topological ...
Vor 4 Tagen · The lecture will give an introduction to the field from the perspective of condensed-matter physics. It will cover concrete model systems for quantum phase transitions, universal aspects of classical and quantum critical phenomena, theoretical methods such as quantum field theories and the renormalization group, as well as advanced ...
Vor 2 Tagen · Our research is within the field of quantum theory of condensed matter systems and quantum information science in the broadest sense (see publications). This includes the study of topological quantum matter, hybrid super-semiconducting systems with exotic quantum states (Majoranas, parafermions, etc.), Luttinger liquids and coupled ...
Vor einem Tag · Introduction.—Quantum spin liquids (QSLs) are ex-otic phases of matter that avoid long-range ordering at zero temperature [1–5]. Rather, these phases are charac-terized by topological order associated with fractionaliza-tion, emergent gauge fields, and Abelian or non-Abelian anyonic quasiparticles. The interest in QSLs was initially
Vor 4 Tagen · Quantum field theory in curved space has gained interest among researchers in theoretical physics. Several investigations explore the effects of the gravitational field produced by curved space on the motions of both relativistic and non-relativistic quantum particles. When solving the wave equations in these curved space backgrounds, the energy eigenvalue expression undergoes modifications ...
Vor 5 Tagen · Non-Hermitian (NH) physics predicts open quantum system dynamics with unique topological features such as exceptional points and the NH skin effect. We show that this new paradigm of topological ...
Vor 3 Tagen · The team demonstrated through theoretical calculations that it is possible to construct QAVs to realize robust Majorana zero modes (MZMs)—exotic topological quantum states within in a mysterious particle proposed by Italian physicist Ettore Majorana in 1937.
