Nonlinear quantum Kibble-Zurek ramps in open systems at finite temperature
Johannes N. Kriel, Emma C. King, Michael Kastner
We analyze quantum systems under a broad class of protocols in which the temperature and a Hamiltonian control parameter are ramped simultaneously and, in general, in a nonlinear f…
Long-range systems, (non)extensivity, and the rescaling of energies
Michael Kastner
Systems with long-range interactions have seen a surge of interest in the past decades. In the wake of this surge, the use of a system size-dependent rescaling, sometimes termed "K…
Ancilla-free measurement of out-of-time-ordered correlation functions: General measurement protocol and Rydberg atom implementation
Michael Kastner, Philip Osterholz, Christian Gross
We introduce a protocol that gives access to out-of-time-ordered correlation functions in many-body quantum systems. Unlike other such protocols, our proposal, which can be applied…
Comment on ``A Comparison Between Broad Histogram and Multicanonical Methods''
M. Kastner, M. Promberger
A recent paper by A. R. Lima, P. M. C. de Oliveira, and T. J. P. Penna [cond-mat/0002176; J. Stat. Phys. 99:691 (2000)], seems to contain at least two mistakes which deserve commen…
Consistency of Microcanonical and Canonical Finite-Size Scaling
M. Kastner, M. Promberger
Typically, in order to obtain finite-size scaling laws for quantities in the microcanonical ensemble, an assumption is taken as a starting point. In this paper, consistency of such…
