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…
Higher spin Richardson-Gaudin model with time-dependent coupling: Exact dynamics
Suvendu Barik, Lieuwe Bakker, Vladimir Gritsev +2
We determine the exact asymptotic many-body wavefunction of a spin- Richardson-Gaudin model with a coupling inversely proportional to time, for time evolution starting from the…
Knizhnik-Zamolodchikov equations and integrable hyperbolic Landau-Zener models
Suvendu Barik, Lieuwe Bakker, Vladimir Gritsev +1
We study the relationship between integrable Landau-Zener (LZ) models and Knizhnik-Zamolodchikov (KZ) equations. The latter are originally equations for the correlation functions o…
Novel approach of exploring ASEP-like models through the Yang Baxter Equation
Suvendu Barik, Alexander. S. Garkun, Vladimir Gritsev
We explore the algebraic structure of a particular ansatz of Yang Baxter Equation which is inspired from the Bethe Ansatz treatment of the ASEP spin-model. Various classes of Hamil…
New spectral-parameter dependent solutions of the Yang-Baxter equation
Alexander. S. Garkun, Suvendu K. Barik, Aleksey K. Fedorov +1
The Yang-Baxter Equation (YBE) plays a crucial role for studying integrable many-body quantum systems. Many known YBE solutions provide various examples ranging from quantum spin c…
Decaying dark matter in dwarf spheroidal galaxies: Prospects for X-ray and gamma-ray telescopes
Shin'ichiro Ando, Suvendu K. Barik, Zhuoran Feng +12
Dwarf spheroidal galaxies are dark matter dominated systems, and as such, ideal for indirect dark matter searches. If dark matter decays into high-energy photons in the dwarf galax…
Remarks on the preservation of no-signaling principle in parity-time-symmetric quantum mechanics
Bijan Bagchi, Suvendu Barik
Working within the framework of parity-time-symmetric quantum mechanics we look into the possibility of entanglement generation and demonstrate that the feature of non-violation of…
