Exact many-body wavefunction of the Kondo model with time-dependent interaction strength
Parameshwar R. Pasnoori, Emil. A. Yuzbashyan
Quantum integrabilty has been applied to a large variety of low dimesional Hamiltonians in Quantum Field Theory, Condensed Matter Physics, and Statistical Mechanics to obtain exact…
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…
The measurement-induced phase transition in strongly disordered spin chains
Yicheng Tang, Pradip Kattel, Arijeet Pal +2
We investigate the dynamics of strongly disordered spin chains in the presence of random local measurements. By studying the transverse-field Ising model with a site-dependent rand…
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…
Turning Down the Noise: Power-Law Decay and Temporal Phase Transitions
Lieuwe Bakker, Suvendu Barik, Vladimir Gritsev +1
We determine the late-time dynamics of a generic spin ensemble with inhomogeneous broadening - equivalently, qubits with arbitrary Zeeman splittings - coupled to a dissipative envi…
Fundamental limits on the electron-phonon coupling and superconducting
Dmitrii V. Semenok, Boris L. Altshuler, Emil A. Yuzbashyan
Fundamental upper bounds on the electron-phonon interaction strength and superconducting transition temperature in metals are established based on the intrinsic instability o…
