Conditional-path Monte Carlo for rare stochastic dynamics on networks: Details and derivations
Thomas Barthel, Jiazheng Sun, Jhao-Hong Peng
The simulation of rare macroscopic events in stochastic network dynamics, such as widespread epidemic outbreaks, cascading failures in communication networks, or the escape from me…
Rare-event sampling for stochastic dynamics in network systems using cluster updates
Jiazheng Sun, James Moody, Thomas Barthel
Understanding the stochastic evolution in complex networks is a central challenge across physics, biology, engineering, social science, and finance. The most consequential macrosco…
Cost scaling of MPS and TTNS simulations for 2D and 3D systems with area-law entanglement
Thomas Barthel
Tensor network states are an indispensable tool for the simulation of strongly correlated quantum many-body systems. In recent years, tree tensor network states (TTNS) have been su…
Tree tensor network states represent low-energy states faithfully
Thomas Barthel
Extending corresponding results for matrix product states [Verstraete and Cirac, PRB 73, 094423 (2006); Schuch et al. PRL 100, 030504 (2008)], it is shown how the approximation err…
Non-Gaussian Phase Transition and Cascade of Instabilities in the Dissipative Quantum Rabi Model
Mingyu Kang, Yikang Zhang, Kenneth R. Brown +1
The open quantum Rabi model describes a two-level system coupled to a harmonic oscillator. A Gaussian phase transition for the nonequilibrium steady states has been predicted when…
Conditions for Unitarity in Timeless Quantum Theory
Simone Rijavec
Quantum timeless approaches solve the problem of time by recovering the usual unitary evolution of quantum theory relative to a clock in a stationary quantum Universe. For some Ham…
