Simulating Lattice Gauge Theories with Virtual Rishons
David Rogerson, João Barata, Robert M. Konik +2
Classical tensor network and hybrid quantum-classical algorithms are promising candidates for the investigation of real-time properties of lattice gauge theories. We develop here a…
Breakdown of Quantum Chaos in the Staggered-Field XXZ Chain: Confinement and Meson Formation
Julia Wildeboer, Marton Lajer, Robert M. Konik
Confinement produces mesonic bound states, but their existence alone does not determine the statistical organization of the many-body spectrum. We investigate this connection in th…
Signatures of Topological Symmetries on a Noisy Quantum Simulator
Christopher Lamb, Robert M. Konik, Hubert Saleur +1
Topological symmetries, invertible and otherwise, play a fundamental role in the investigation of quantum field theories. Despite their ubiquitous importance across a multitude of…
Universal Euler-Cartan Circuits for Quantum Field Theories
Ananda Roy, Robert M. Konik, David Rogerson
Quantum computers can efficiently solve problems which are widely believed to lie beyond the reach of classical computers. In the near-term, hybrid quantum-classical algorithms, wh…
Scattering Processes from Quantum Simulation Algorithms for Scalar Field Theories
Andrew Hardy, Priyanka Mukhopadhyay, M. Sohaib Alam +8
We provide practical simulation methods for scalar field theories on a quantum computer that yield improved asymptotics as well as concrete gate estimates for the simulation and ph…
High-temperature quantum coherence of spinons in a rare-earth spin chain
Lazar L. Kish, Andreas Weichselbaum, Daniel M. Pajerowski +6
Conventional wisdom dictates that quantum effects become unimportant at high temperatures. In magnets, when the thermal energy exceeds interactions between atomic magnetic moments,…
Witnessing Quantum Entanglement Using Resonant Inelastic X-ray Scattering
Tianhao Ren, Yao Shen, Marton Lajer +9
Although entanglement is both a central ingredient in our understanding of quantum many-body systems and an essential resource for quantum technologies, we only have a limited abil…

Rajesh K. Malla, Hiroki Sukeno, Hongye Yu +3
In recent quantum algorithmic developments, a feedback-based approach has shown promise for preparing quantum many-body system ground states and solving combinatorial optimization…
Efficient Quantum Circuits based on the Quantum Natural Gradient
Ananda Roy, Sameer Erramilli, Robert M. Konik
Efficient preparation of arbitrary entangled quantum states is crucial for quantum computation. This is particularly important for noisy intermediate scale quantum simulators relyi…
Prethermalization in coupled one-dimensional quantum gases
Maciej Łebek, Miłosz Panfil, Robert M. Konik
We consider the problem of the development of steady states in one-dimensional Bose gas tubes that are weakly coupled to one another through a density-density interaction. We analy…
Duality and Form Factors in the Thermally Deformed Two-Dimensional Tricritical Ising Model
A. Cortés Cubero, R. M. Konik, M. Lencsés +2
The thermal deformation of the critical point action of the 2D tricritical Ising model gives rise to an exact scattering theory with seven massive excitations based on the exceptio…
Hydrodynamics of the interacting Bose gas in the Quantum Newton Cradle setup
Jean-Sébastien Caux, Benjamin Doyon, Jérôme Dubail +2
Describing and understanding the motion of quantum gases out of equilibrium is one of the most important modern challenges for theorists. In the groundbreaking Quantum Newton Cradl…
High-temperature charge density wave correlations in LaBaCuO without spin-charge locking
H. Miao, J. Lorenzana, G. Seibold +11
Although all superconducting cuprates display charge-ordering tendencies, their low-temperature properties are distinct, impeding efforts to understand the phenomena within a singl…
