Ph.D. in Theoretical Physics – Quantum Many-Body Systems, Coherence & Transport

Department of Physics, School of Natural Sciences, Shiv Nadar Institution of Eminence (SNIoE), Delhi–NCR

Are you fascinated by how quantum systems maintain order in a noisy world? 🌌

We are building a group that explores how quantum coherence, dissipation, and driving combine to create stable quantum behaviour in real systems — even far from equilibrium.

We use analytical theory and advanced computational methods to study quantum coherence, transport, spin selectivity, and ultrafast optical dynamics across platforms ranging from quantum materials to molecular and photonic systems. A growing part of our research investigates nonlinear and time-varying optical properties, revealing how intense light fields can transiently reshape matter and control its quantum states. ⚡

1️⃣ Quantum Coherence under Dissipation – Driven–dissipative many-body systems using Lindblad master equations and tensor-network (MPS/TDVP) simulations to uncover emergent order and time-crystalline behaviour.

2️⃣ Microscopic Theory of CISS – Understanding how molecular chirality, spin–orbit coupling, and quantum coherence give rise to spin-selective transport.

3️⃣ Quantum Transport & Non-Markovian Dynamics – Exploring energy and spin currents in open fermionic systems and spin chains, and how memory effects influence steady states.

4️⃣ Quantum & Optical Dynamics of Time-Varying Materials – Modelling nonlinear and ultrafast optical responses in low-electron-density Drude (LEDD) materials driven by few-cycle laser pulses.

Our research bridges quantum theory, computation, and materials physics, offering opportunities at the interface of quantum technology, spintronics, and nonlinear optics.

Students will have access to high-performance computing clusters and dedicated high-memory workstations at SNIoE. Collaborative projects may involve international groups depending on project fit and available support.

Candidates with strong backgrounds in quantum mechanics, statistical physics, or condensed matter theory are encouraged to apply. Experience with numerical computation (Python, Julia, or MATLAB) is desirable but not mandatory.

All full-time PhD students receive a monthly fellowship (₹45,000 → ₹50,000 over five years) plus tuition and hostel fee waivers, and up to ₹1.5 lakh in travel support for conferences. ✈️

Apply through the Shiv Nadar University PhD portal (Spring 2026) by November 9, 2025.
