Real critical exponents from the -expansion in an interacting model with non-Hermitian anisotropy

Eduard Naichuk, Jeroen van den Brink, Flavio S. Nogueira

In quantum optics and condensed matter physics non-Hermitian phenomena are often studied under the assumption of an open physical system. However, there are examples of intrinsical…

Multi-block exceptional points in open quantum systems

Aysel Shiralieva, Grigory A. Starkov, Björn Trauzettel

Open quantum systems can be approximately described by non-Hermitian Hamiltonians (NHHs) and Liouvillian superoperators. The two approaches differ by quantum jump terms correspondi…

Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis

Atanu Patra, Paul Konrad, Andreas Sperlich +6

Negatively charged boron vacancies () in hexagonal boron nitride (hBN) are emerging as promising solid-state spin qubits due to their optical accessibility, structu…

Local Information Flow in Quantum Quench Dynamics

Nicolas P. Bauer, Björn Trauzettel, Thomas Klein Kvorning +2

We investigate the out-of-equilibrium dynamics of quantum information in one-dimensional systems undergoing a quantum quench using a local perspective based on the information latt…

Asymptotic Exceptional Steady States in Dissipative Dynamics

Yu-Min Hu, Jan Carl Budich

Spectral degeneracies in Liouvillian generators of dissipative dynamics generically occur as exceptional points, where the corresponding non-Hermitian operator becomes non-diagonal…

Intermediate Excited State Relaxation Dynamics of Boron Vacancy Spin Defects in Hexagonal Boron Nitride

Paul Konrad, Mehran Kianinia, Lesley Spencer +5

Optically addressable spin defects in hexagonal boron nitride offer promising potential for 2D quantum sensing, though excited-state dynamics remain poorly understood. In particula…
