چکیده
We provide a detailed calculation, and description of the quench and probe protocol described in the letter. The protocol described in letter consists of the following steps: (1) prepare the state in the ground state of some Hamiltonian |ψ0〉; (2) at t = 0 quench a parameter in that Hamiltonian; (3) pulse the evolved wave function at t = t1 (called |ψ1〉) by letting k → k − eA; and (4) measure Hall current after the wave function has evolved to t = t2 (called |ψ2〉).

Remnant Geometric Hall Response in a Quantum Quench.
Out-of-equilibrium systems can host phenomena that transcend the usual restrictions of equilibrium systems. Here, we unveil how out-of-equilibrium states, prepared via a quantum quench in a two-band system, can exhibit a nonzero Hall-type current-a remnant Hall response-even when the instantaneous Hamiltonian is time reversal symmetric (in contrast to equilibrium Hall currents). Interestingly, ...
متن کاملPersistent Hall response in a quantum quench
Out-of-equilibrium systems can host phenomena that transcend the usual restrictions of equilibrium systems. Here we unveil how out-of-equilibrium states, prepared via a quantum quench, can exhibit a non-zero Hall-type response that persists at long times, and even when the instantaneous Hamiltonian is time reversal symmetric; both these features starkly contrast with equilibrium Hall currents. ...
متن کاملInvestigating and Analyzing the Geometric proportions of the Works of Qavam al-Din Shirazi Case Study: "Goharshad Mosque in Mashhad and Goharshad Mosque in Herat"
Qavam al-Din Shirazi is one of the prominent architects of the Timurid era who has memorized many works such as the Goharshad Mosque in Mashhad and the Herat Goharshad Mosque. What is considered as an architectural work in the study of a building is the material and physical aspects of the architectural space. Due to the destruction of Heratchr('39')s Goharshad Mosque, one of the ways to unders...
متن کاملبررسی اثر صحیح کوانتومی هال در سیستمهای دارای ناخالصی به روش تبدیل پیمانه‌ای در حضور نقطه‌های کوانتومی
In this paper we study the integer quantum Hall effect (IQHE) on the systems with different types of impurities in delta and gaussian forms. The Landau energy levels in the presence of impurity split in two different levels,the extended and localized levels, emerging then the Hall step. Finally, we add a specified form of a quantum dot potential to a system with impurity, and observed that incr...
متن کاملHaldane quantum Hall effect for light in a dynamically modulated array of resonators: supplementary material
The spectrum εn has a Brillouin-zone like structure with Ω the width of the first zone, i.e. for any solution |un(t)〉 of quasienergy εn, and any integer m, exp(imΩt)|un(t)〉 is also a solution, with eigenvalue εn + mΩ. The states |un(t)〉 form a Hilbert space of T-periodic functions. The inner product in this space can be defined starting from the standard bra-ket inner product 〈•|•〉 for time-ind...
