Phonon chirality as an additive control of CISS: a symmetry-protected law
Shi-Qi Zhang, Vipul Upadhyay, Jiayue Han +2
Chirality-induced spin selectivity (CISS) is usually associated with molecular handedness. The possible contribution of chiral phonons is less established. We study a helical tight…
Weak Electron-Phonon Coupling Is Insufficient to Generate Significant CISS in Two-Terminal Transport
Vipul Upadhyay, Amikam Levy
A central open question in chiral-induced spin selectivity (CISS) is whether weak electron-phonon coupling in a helical molecular junction can generate a sizable spin polarization…
Modified Quantum Wheatstone Bridge based on current circulation
Vipul Upadhyay, Rahul Marathe
We investigate a simple fermionic system designed to detect an unknown hopping rate between two sites by analyzing current circulation. The system exploits geometric asymmetry and…
Quantum thermometry for ultralow temperatures using probe and ancilla qubit chains
Asghar Ullah, Vipul Upadhyay, Özgür E. Müstecaplıoğlu
We propose a scheme to enhance the range and precision of ultralow temperature measurements by employing a probe qubit coupled to a chain of ancilla qubits. Specifically, we analyz…
Current circulation near additional energy degeneracy points in quadratic Fermionic networks
Vipul Upadhyay, Rahul Marathe
We study heat and particle current circulation (CC) in quadratic Fermionic systems analysed using a general dissipative Lindbladian master equation. It was observed in an earlier s…
Signature of topology via heat transfer analysis in the Su-Schrieffer-Heeger (SSH) model
Vipul Upadhyay, M. Tahir Naseem, Özgür E. Müstecaplıoğlu +1
In this work, we explore the potential of thermodynamics as a tool for identifying the topological phase transition. Specifically, we focus on a one-dimensional Su-Schrieffer-Heege…
