Weyl's Relations, Integrable Matrix Models and Quantum Computation
B. Sriram Shastry, Emil A. Yuzbashyan, Aniket Patra
Starting from a generalization of Weyl's relations in finite dimension , we show that the Heisenberg commutation relations can be satisfied in a specific dimensional subsp…
Trotter transition in BCS pairing dynamics
Aniket Patra, Emil A. Yuzbashyan, Boris L. Altshuler +1
We study universal aspects of thermalization induced by Trotterization, a procedure routinely used in gate-based quantum computation. We use the reduced-BCS model -- quantum integr…
Instability of metals with respect to strong electron-phonon interaction
Emil A. Yuzbashyan, Boris L. Altshuler, Aniket Patra
We show that thermal equilibrium between conduction electrons and phonons becomes kinetically unstable when the renormalized electron-phonon coupling exceeds a certain threshold. W…
Dynamical chaos in the integrable Toda chain induced by time discretization
Carlo Danieli, Emil A. Yuzbashyan, Boris L. Altshuler +2
We use the Toda chain model to demonstrate that numerical simulation of integrable Hamiltonian dynamics using time discretization destroys integrability and induces dynamical chaos…
Continuum limit of lattice quasielectron wavefunctions
Aniket Patra, Birgit Hillebrecht, Anne E. B. Nielsen
Trial states describing anyonic quasiholes in the Laughlin state were found early on, and it is therefore natural to expect that one should also be able to create anyonic quasielec…
Driven-Dissipative Dynamics of Atomic Ensembles in a Resonant Cavity II: Quasiperiodic Route to Chaos and Chaotic Synchronization
Aniket Patra, Boris L. Altshuler, Emil A. Yuzbashyan
We analyze the origin and properties of the chaotic dynamics of two atomic ensembles in a driven-dissipative experimental setup, where they are collectively damped by a bad cavity…
Single-shot determination of quantum phases via continuous measurements
Aniket Patra, Lukas F. Buchmann, Felix Motzoi +3
We propose that weak continuous probing may be exploited to determine and define quantum phases of complex many-body systems based on the measurement record alone. We test the resu…
Chaotic Synchronization between Atomic Clocks
Aniket Patra, Boris L. Altshuler, Emil A. Yuzbashyan
We predict synchronization of the chaotic dynamics of two atomic ensembles coupled to a heavily damped optical cavity mode. The atoms are dissipated collectively through this mode…
Driven-Dissipative Dynamics of Atomic Ensembles in a Resonant Cavity I: Nonequilibrium Phase Diagram and Periodically Modulated Superradiance
Aniket Patra, Boris L. Altshuler, Emil A. Yuzbashyan
We study the dynamics of two ensembles of atoms (or equivalently, atomic clocks) coupled to a bad cavity and pumped incoherently by a Raman laser. Our main result is the nonequilib…
Integrable time-dependent quantum Hamiltonians
Nikolai A. Sinitsyn, Emil A. Yuzbashyan, Vladimir Y. Chernyak +2
We formulate a set of conditions under which dynamics of a time-dependent quantum Hamiltonian are integrable. The main requirement is the existence of a nonabelian gauge field with…
Quantum integrability in the multistate Landau-Zener problem
Aniket Patra, Emil A. Yuzbashyan
We analyze Hamiltonians linear in the time variable for which the multistate Landau-Zener problem is known to have an exact solution. We show that they either belong to families of…
