Heat-to-motion conversion for quantum active matter
Alexander-Georg Penner, Ludmila Viotti, Rosario Fazio +2
We introduce a model of an active quantum particle and discuss its properties. The particle has a set of internal states that mediate exchanges of heat with external reservoirs. He…
Subharmonic spin correlations and spectral pairing in Floquet time crystals
Alexander-Georg Penner, Harald Schmid, Leonid I. Glazman +1
Floquet time crystals are characterized by subharmonic behavior of temporal correlation functions. Studying the paradigmatic time crystal based on the disordered Floquet quantum Is…
Self-similar phase diagram of the Fibonacci-driven quantum Ising model
Harald Schmid, Yang Peng, Gil Refael +1
We study a stroboscopic quantum Ising model with Fibonacci dynamics. Focusing on boundary spin correlation functions in long but finite chains, our simulations as well as analytica…
Dirac-point spectroscopy of flat-band systems with the quantum twisting microscope
Nemin Wei, Felix von Oppen, Leonid I. Glazman
Motivated by the recent development of the quantum twisting microscope, we formulate a theory of elastic momentum-resolved tunneling across a planar tunnel junction between a monol…
Hofstadter spectrum of Chern bands in twisted transition metal dichalcogenides
KryÅ¡tof KoláÅ, Kang Yang, Felix von Oppen +1
We study the topological bands in twisted bilayer transition metal dichalcogenides in an external magnetic field. We first focus on a paradigmatic model of WSe, which can be de…
Theory of phonon spectroscopy with the quantum twisting microscope
Jiewen Xiao, Erez Berg, Leonid I. Glazman +3
We develop a theory of probing phonon modes of van-der-Waals materials using the quantum twisting microscope. While elastic tunneling dominates the tunneling current at small twist…
