A cavity quantum electrodynamics implementation of the Sachdev--Ye--Kitaev model
Philipp Uhrich, Soumik Bandyopadhyay, Nick Sauerwein +3
The search for a quantum theory of gravity has led to the discovery of quantum many-body systems that are dual to gravitational models with quantum properties. The perhaps most fam…
Absence of operator growth for average equal-time observables in charge-conserved sectors of the Sachdev-Ye-Kitaev model
Alessio Paviglianiti, Soumik Bandyopadhyay, Philipp Uhrich +1
Quantum scrambling plays an important role in understanding thermalization in closed quantum systems. By this effect, quantum information spreads throughout the system and becomes…
Engineering random spin models with atoms in a high-finesse cavity
Nick Sauerwein, Francesca Orsi, Philipp Uhrich +6
All-to-all interacting, disordered quantum many-body models have a wide range of applications across disciplines, from spin glasses in condensed-matter physics, over holographic du…
Detecting quantum phase transitions in the quasi-stationary regime of Ising chains
Ceren B. Dağ, Philipp Uhrich, Yidan Wang +2
Recently, single-site observables have been shown to be useful for the detection of dynamical criticality due to an emergence of a universal critically-prethermal temporal regime i…
Universal equilibration dynamics of the Sachdev-Ye-Kitaev model
Soumik Bandyopadhyay, Philipp Uhrich, Alessio Paviglianiti +1
Equilibrium quantum many-body systems in the vicinity of phase transitions generically manifest universality. In contrast, limited knowledge has been gained on possible universal c…
Probing dynamical criticality near quantum phase transitions
Ceren B. Dağ, Yidan Wang, Philipp Uhrich +2
We reveal a prethermal temporal regime upon suddenly quenching to the vicinity of a quantum phase transition in the time evolution of 1D spin chains. The prethermal regime is analy…
Cryogenic electro-optic interconnect for superconducting devices
Amir Youssefi, Itay Shomroni, Yash J. Joshi +5
Encoding information onto optical fields is the backbone of modern telecommunication networks. Optical fibers offer low loss transport and vast bandwidth compared to electrical cab…
Out-of-equilibrium phase diagram of long-range superconductors
Philipp Uhrich, Nicolò Defenu, Rouhollah Jafari +1
Within the ultimate goal of classifying universality in quantum many-body dynamics, understanding the relation between out-of-equilibrium and equilibrium criticality is a crucial o…
Probing unitary two-time correlations in a neutral atom quantum simulator
Philipp Uhrich, Christian Gross, Michael Kastner
Measuring unitarily-evolved quantum mechanical two-time correlations is challenging in general. In a recent paper [P.~Uhrich {\em et al.}, Phys.\ Rev.~A {\bf 96}, 022127 (2017)], a…
Reducing backaction when measuring temporal correlations in quantum systems
Michael Kastner, Philipp Uhrich
Dynamic correlations of quantum observables are challenging to measure due to measurement backaction incurred at early times. Recent work [P. Uhrich et al., Phys. Rev. A, 96:022127…
Noninvasive Measurement of Dynamic Correlation Functions
Philipp Uhrich, Salvatore Castrignano, Hermann Uys +1
The measurement of dynamic correlation functions of quantum systems is complicated by measurement backaction. To facilitate such measurements we introduce a protocol, based on weak…
